• Electromagnetic field exposure affects the calling song, phonotaxis, and level of biogenic amines in crickets

  Joanna Wyszkowska, Jarosław Kobak, Hitoshi Aonuma

  Abstract The electromagnetic field (EMF) is ubiquitous in the environment, constituting a well-known but poorly understood stressor. Few studies have been conducted on insect responses to EMF, although they are an excellent experimental model and are of great ecological importance. In our work, we tested the effects of EMF (50 Hz, 7 mT) on the cricketGryllus bimaculatus: the male calling song pattern, female mate choice, and levels of biogenic amines in the brain. Exposure of males to EMF increased the number and shortened the period of chips in their calling song (by 2.7% and 5% relative to the control song, respectively), but not the sound frequency. Aged (3-week-old) females were attracted to both natural and EMF-modified male signals, whereas young (1-week-old, virgin) females responded only to the modified signal, suggesting its higher attractance. Stress response of males to EMF may be responsible for the change in the calling song, as suggested by the changes in the amine levels in their brains: an increase in dopamine (by 50% relative to the control value), tyramine (65%), and serotonin (25%) concentration and a decrease in octopamine level (by 25%). These findings indicate thatG. bimaculatusresponds to EMF, like stressful conditions, which may change the condition and fitness of exposed individuals, disrupt mate selection, and, in consequence, affect the species’ existence.

• Photoreceptor genes in a trechine beetle, Trechiama kuznetsovi, living in the upper hypogean zone

  Takuma Niida, Yuto Terashima, Hitoshi Aonuma, Shigeyuki Koshikawa

  Abstract To address how organisms adapt to a new environment, subterranean organisms whose ancestors colonized subterranean habitats from surface habitats have been studied. Photoreception abilities have been shown to have degenerated in organisms living in caves and calcrete aquifers. Meanwhile, the organisms living in a shallow subterranean environment, which are inferred to reflect an intermediate stage in an evolutionary pathway to colonization of a deeper subterranean environment, have not been studied well. In the present study, we examined the photoreception ability in a trechine beetle, Trechiama kuznetsovi, which inhabits the upper hypogean zone and has a vestigial compound eye. By de novo assembly of genome and transcript sequences, we were able to identify photoreceptor genes and phototransduction genes. Specifically, we focused on opsin genes, where one long wavelength opsin gene and one ultraviolet opsin gene were identified. The encoded amino acid sequences had neither a premature stop codon nor a frameshift mutation, and appeared to be subject to purifying selection. Subsequently, we examined the internal structure of the compound eye and nerve tissue in the adult head, and found potential photoreceptor cells in the compound eye and nerve bundle connected to the brain. The present findings suggest that T. kuznetsovi has retained the ability of photoreception. This species represents a transitional stage of vision, in which the compound eye regresses, but it may retain the ability of photoreception using the vestigial eye.

• A symbiotic aphid selfishly manipulates attending ants via dopamine in honeydew

  Tatsumi Kudo, Hitoshi Aonuma, Eisuke Hasegawa

  AbstractSymbiotic relationships are widespread in nature, but the mechanisms maintaining these relationships remain to be elucidated because symbiosis incurs a maintenance cost to each participant, which lowers its reproductive rate. In host-parasite relationships, parasites are known to manipulate the host's behavior selfishly, and there is an arms race between them. Selfish manipulations also occur in symbiosis, but the effects of selfish manipulations on symbiosis are not fully understood. Here, we show that an ant-associated aphid manipulates attending ants to receive stronger protection. Aphid honeydew regurgitated by ants contains dopamine (DA). The ants showed low aggressiveness before contact with the aphids, but it rose after contact. Administration of DA to the ants increased ant aggressiveness as the concentration increased, while an antagonist of DA inhibited this effect. The other 3 amines showed no effect on aggressiveness. A previous study showed that attending ants selfishly manipulate aphids by increasing the reproductive rate of green morph to obtain high-quality honeydew. These results suggest that mutual selfish manipulation benefits both participants and is likely to strengthen symbiosis. The selfishness of each participant may contribute to sustaining this symbiosis because their selfishness increases their long-term fitness.

• Fold analysis of crumpled sheets using microcomputed tomography

  Yumino Hayase, Hitoshi Aonuma, Satoshi Takahara, Takahiro Sakaue, Shun'ichi Kaneko, Hiizu Nakanishi

  Hand-crumpled paper balls involve intricate structure with a network of creases and vertices, yet show simple scaling properties, which suggests self-similarity of the structure. We investigate the internal structure of crumpled papers by the microcomputed tomography (micro-CT) without destroying or unfolding them. From the reconstructed three-dimensional (3D) data, we examine several power laws for the crumpled square sheets of paper of the sizes L=50-300 mm and obtain the mass fractal dimension D_{M}=2.7±0.1 by the relation between the mass and the radius of gyration of the balls and the fractal dimension 2.5≲d_{f}≲2.8 for the internal structure of each crumpled paper ball by the box counting method in the real space and the structure factors in the Fourier space. The data for the paper sheets are consistent with D_{M}=d_{f}, suggesting that the self-similarity in the structure of each crumpled ball gives rise to the similarity among the balls with different sizes. We also examine the cellophane sheets and the aluminium foils of the size L=200 mm and obtain 2.6≲d_{f}≲2.8 for both of them. The micro-CT also allows us to reconstruct 3D structure of a line drawn on the crumpled sheets of paper. The Hurst exponent for the root-mean-square displacement along the line is estimated as H≈0.9 for the length scale shorter than the scale of the radius of gyration, beyond which the line structure becomes more random with H∼0.5.

• Social Evolution With Decoupling of Multiple Roles of Biogenic Amines Into Different Phenotypes in Hymenoptera

  Ken Sasaki, Yasukazu Okada, Hiroyuki Shimoji, Hitoshi Aonuma, Toru Miura, Kazuki Tsuji

  Convergent evolution of eusociality with the division of reproduction and its plastic transition in Hymenoptera has long attracted the attention of researchers. To explain the evolutionary scenario of the reproductive division of labor, several hypotheses had been proposed. Among these, we focus on the most basic concepts, i.e., the ovarian ground plan hypothesis (OGPH) and the split-function hypothesis (SFH). The OGPH assumes the physiological decoupling of ovarian cycles and behavior into reproductive and non-reproductive individuals, whereas the SFH assumes that the ancestral reproductive function of juvenile hormone (JH) became split into a dual function. Here, we review recent progress in the understanding of the neurohormonal regulation of reproduction and social behavior in eusocial hymenopterans, with an emphasis on biogenic amines. Biogenic amines are key substances involved in the switching of reproductive physiology and modulation of social behaviors. Dopamine has a pivotal role in the formation of reproductive skew irrespective of the social system, whereas octopamine and serotonin contribute largely to non-reproductive social behaviors. These decoupling roles of biogenic amines are seen in the life cycle of a single female in a solitary species, supporting OGPH. JH promotes reproduction with dopamine function in primitively eusocial species, whereas it regulates non-reproductive social behaviors with octopamine function in advanced eusocial species. The signal transduction networks between JH and the biogenic amines have been rewired in advanced eusocial species, which could regulate reproduction in response to various social stimuli independently of JH action.

• Descending and Ascending Signals That Maintain Rhythmic Walking Pattern in Crickets

  Keisuke Naniwa, Hitoshi Aonuma

  The cricket is one of the model animals used to investigate the neuronal mechanisms underlying adaptive locomotion. An intact cricket walks mostly with a tripod gait, similar to other insects. The motor control center of the leg movements is located in the thoracic ganglia. In this study, we investigated the walking gait patterns of the crickets whose ventral nerve cords were surgically cut to gain an understanding of how the descending signals from the head ganglia and ascending signals from the abdominal nervous system into the thoracic ganglia mediate the initiation and coordination of the walking gait pattern. Crickets whose paired connectives between the brain and subesophageal ganglion (SEG) (circumesophageal connectives) were cut exhibited a tripod gait pattern. However, when one side of the circumesophageal connectives was cut, the crickets continued to turn in the opposite direction to the connective cut. Crickets whose paired connectives between the SEG and prothoracic ganglion were cut did not walk, whereas the crickets exhibited an ordinal tripod gait pattern when one side of the connectives was intact. Crickets whose paired connectives between the metathoracic ganglion and abdominal ganglia were cut initiated walking, although the gait was not a coordinated tripod pattern, whereas the crickets exhibited a tripod gait when one side of the connectives was intact. These results suggest that the brain plays an inhibitory role in initiating leg movements and that both the descending signals from the head ganglia and the ascending signals from the abdominal nervous system are important in initiating and coordinating insect walking gait patterns.

• Leg amputation modifies coordinated activation of the middle leg muscles in the cricket Gryllus bimaculatus

  Dai Owaki, Hitoshi Aonuma, Yasuhiro Sugimoto, Akio Ishiguro

  Insects alter their walking pattern in order to respond to demands of an ever-changing environment, such as varying ground surface textures. They also exhibit resilient and flexible ability to retain the capacity to walk even after substantial changes in their body properties, e.g. leg amputation. While the motor control paradigm governing the inter-leg coordination in such adaptive walking has been extensively described in past studies, the mechanism remains unknown. Here, we examined this question by using the cricket (Gryllus bimaculatus), which shows a tetrapod/tripod gait on a flat surfaces, like many other insects. We performed leg amputation experiments to investigate modifications of leg movements and coordination of muscle activities. We simultaneously recorded (1) the leg movements, locomotion velocity, and body rotation and (2) the leg movements and leg muscles activities before and after leg amputation. Crickets displayed adaptive coordination of leg movement patterns in response to amputations. The activation timings of levator muscles in both middle legs tended to synchronize in phase when both legs were amputated at the coxatrochanteral joint. This supports the hypothesis that an intrinsic contralateral connection within the mesothoracic ganglion exists, and that mechanosensory feedback from the legs override this connection, resulting in the anti-phase movement of a normal gait.

• Novel Method for Analyzing Flexible Locomotion Patterns of Animals by Using Polar Histogram

  Hitoshi Aonuma

  In general, legged robots are designed to walk with a fixed rhythmic pattern. However, most animals can adapt their limb movements while walking. It is necessary to understand the mechanism of adaptability during locomotion when designing bio-inspired legged robots. In this paper, we propose an approach to analyze the flexible locomotion pattern of animals using a polar histogram. Field crickets were used to investigate variations in leg movement of insects depending on the environment. Crickets have a tripod gait; however, their leg movement changes depending on the texture of the ground. There was a significant difference between the leg movement when walking and when swimming. Our approach can explain how animals move their legs during locomotion. This study is useful for evaluating the movements of legged robots.

• Serotonergic control in initiating defensive responses to unexpected tactile stimuli in the trap-jaw ant Odontomachus kuroiwae

  Hitoshi Aonuma

  The decision to express either a defensive response or an escape response to a potential threat is crucial for insects to survive. This study investigated an aminergic mechanism underlying defensive responses to unexpected touch in an ant that has powerful mandibles, the so-called trap-jaw. The mandibles close extremely quickly and are used as a weapon during hunting. Tactile stimulation to the abdomen elicited quick forward movements in a dart escape in 90% of the ants in a colony. Less than 10% of the ants responded with a quick defensive turn towards the source of stimulation. To reveal the neuronal mechanisms underlying this defensive behavior, the effect of brain biogenic amines on the responses to tactile stimuli were investigated. The levels of octopamine (OA), dopamine (DA) and serotonin (5HT) in the brain were significantly elevated in ants that responded with a defensive turn to the unexpected stimulus compared to ants that responded with a dart escape. Oral administration of DA and 5HT demonstrated that both amines contributed to the initiation of a defensive responses. Oral administration of L-DOPA weakly affected the initiation of the defensive turn, while 5-hydroxy-L-tryptophan (5HTP) strongly affected the initiation of defensive behavior. Oral administration of ketanserin, a 5HT antagonist, inhibited the initiation of the defensive turn in aggressive workers, abolishing the effects of both 5HT and 5HTP on the initiation of turn responses. These results indicate that 5HTergic control in the nervous system is a key for the initiation of defensive behavior in the trap-jaw ant.

  SUGIMOTO Yasuhiro, NANIWA Keisuke, AONUMA Hitoshi, Osuka Koichi

  Research that attempts to elucidate adaptive gait realization mechanism is underway through walking experiment with zombified crickets, based on the interesting behavior of Ampulex compressa. In this research, it is important to prepare a large number of experimental individuals with the same quality (degree of zombification). In this study, we developed a new system to support and semi-automate the injection for cricket zombification. The developed system consists of two cameras, micromanipulator and syringe pump and these devices are operated from PC in order to inject the injection needle at the same position and depth and inject the same amount of liquid medicine. The validity and practicality of the developed system were confirmed by verification experiments.

Biology researches have to observe target behavior with recording video and have to spend much time for analyzing video data afterward. Here we focus on fighting behavior between male crickets. Fighting behavior is one of the common behaviors in animals. Animals usually fight for resources like foods, territory, mating partner and so on. During a fight, animals modify their aggressive motivation and behavior. In order to understand how they alter their motivation and behavior, we need to analyze the detail of the time sequence of the fighting. Therefore, we propose the video image processing method for automated observation, which enables us to observe and measure the behavioral characteristics of plural crickets simultaneously. Finally, through experiments we prove the effectiveness of our method.

• A Neuromodulation Model for Adaptive Behavior Selection by the Cricket – Nitric Oxide (NO)/Cyclic Guanosine MonoPhosphate (cGMP) Cascade Model –

  Kuniaki Kawabata, Tomohisa Fujiki, Yusuke Ikemoto, Hitoshi Aonuma, Hajime Asama

  Physiological research has shown the importance of neuromodulators such as nitric oxide (NO) in the pheromone behavior such as fighting behavior in insects. We focused on modeling function of neuromodulator in fighting behavior of crickets, and to emerge adaptive behavior selection by synthetic approach. In this paper, we propose a model for adaptive behavior selection by nitric oxide (NO)/cyclic guanosine monophosphate (cGMP) cascade based on the physiological knowledge, and discuss the result of computer simulation.

• Embodied Latch Mechanism of the Mandible to Power at an Ultrahigh Speed in the Trap-jaw AntsOdontomachus kuroiwae

  Hitoshi Aonuma, Keisuke Naniwa, Yasuhiro Sugimoto, Kyohsuke Ohkawara, Katsushi Kagaya

  Abstract Rapid movements of limbs and appendages, faster than those produced by simple muscle contraction alone, are generated through mechanical networks consisting of springs and latches. The latch plays a central role in these spring-loaded mechanisms, but the structural details of the latch are not always known. The mandibles of the trapjaw antOdontomachus kuroiwaecloses the mandible extremely quickly to capture prey or to perform mandible-powered defensive jumps to avoid potential threats. The jump is mediated by a mechanical spring and latch system embodied in the mandible. An ant can strike the tip of the mandible onto the surface of an obstacle (prey, predator, or ground) in order to bounce its body away from potential threats. The angular velocity of the closing mandible was 2.3×10⁴rad/s. Latching of the joint is a key mechanism to aid the storage of energy required to power the ballistic movements of the mandibles. We have identified the fine structure of two latch systems on the mandible forming a ‘balljoint’ using an X-ray micro-computational tomography system (X-ray micro-CT) and X-ray live imaging with a synchrotron. Here we describe the surface of the inner section of the socket and a projection on the lip of the ball. The X-ray live imaging and movements of the 3D model show that the ball with a detent ridge slipped into a socket and over the socket ridge before snapping back at the groove edge. Our results give insight into the complex spring-latch systems that underpin ultra-fast movements in biological systems.

• Descending and ascending signals that maintain rhythmic walking pattern in the cricket

  Keisuke Naniwa, Hitoshi Aonuma

  The cricket is one of the model animals used to investigate the neuronal mechanisms underlying adaptive locomotion. An intact cricket walks with a tripod gait, similar to other insects. The motor control center of the leg movements is located in the thoracic ganglia. In this study, we investigated the walking gait patterns of crickets whose ventral nerve cords were surgically cut to gain an understanding of how the descending signals from the head ganglia and ascending signals from the abdominal nervous system into the thoracic ganglia mediate the initiation and coordination of the walking gait pattern. Crickets whose paired connectives between the brain and subesophageal ganglion (SEG) were cut exhibited a tripod gait pattern. However, when one side of the connectives between the brain and SEG was cut, the crickets continued to turn in the opposite direction to the connective cut. Crickets whose paired connectives between the SEG and prothoracic ganglion were cut did not walk, whereas the crickets exhibited an ordinal tripod gait pattern when one side of the connectives was intact. Crickets whose paired connectives between the metathoracic ganglion and abdominal ganglia were cut initiated walking, although the gait was not a coordinated tripod pattern, whereas the crickets exhibited a tripod gait when one side of the connectives was intact. These results suggest that the brain plays an inhibitory role in initiating leg movements, and that both the descending signals from the head ganglia and the ascending signals from the abdominal nervous system are both important in initiating and coordinating insect walking gait patterns.

• 脳による中央制御系を排除したコオロギのふるまい

  浪花啓右, 青沼仁志, 青沼仁志, 杉本靖博, 大須賀公一

  Behavior of insect is not only dominated by central nervous systems (brain). The peripheral nerves and embodiment are also related. However, in real animals, the specific roles of the head ganglia (brain), thoracic ganglion and embodiment are still unknown. In this study, we aim to find the control law embedded in embodiment and thoracic ganglion by confirming the behavior of the head removal cricket. Experimental results show that gait pattern in the head removal cricket is different from that of intact crickets. It also shows that the gait of head removal cricket is unstable, that is, the cooperativeness of each leg is quite low.

• アギトアリ顎部の高速運動を生む関節構造の立体模型を用いた解析

  The trap-jaw ant genus Odontomachus closes her mandible to catch prey quite quickly. The purpose of this study is to examine the mechanism how such a fast movement is realized. Since the velocity of closing exceeds the contraction velocity of a muscle, it is considered that there will be a mechanism to store energy and release it at once for realization of high-speed motion in the exoskeleton. We prepare a scale model of Odontomachus with micro CT scanning their exoskeleton data and 3D printer. Using model, we find three regions of contact points of the temporomandibular joint and the exoskeletal part meshes with each other at one of the regions. This structure is considered to be related to a lock mechanism for fast movement of Odontomachus.

• Development aquatic frog robot with knee extension mechanism driven by dissected muscle

  SAKAI Ryo, SHIMIZU Masahiro, AONUMA Hitoshi, HOSODA Koh

  <p>This study aims to understand relationships between musculoskeletal structure of frogs and swimming performance without control of the nerves systems. Frogs generate great swimming performance by extension of the hind limbs. Extension of knee cannot only generate thrust but also give a load to the Plantaris longus (PL) muscle, which is ankle extensor muscle. We developed an aquatic frog robot, Xenopus-noid, which can extend the knee and is driven by the dissected PL muscle from <i>Xenopus laevis</i>. Xenopus-noid has the knee extension mechanism composed of electrical magnet, a torsion spring positioned in hip joint. An energy of a torsion spring is released by turning off of an electrical magnet. In this study, we confirmed that the knee extension of Xenopus-noid is similar to that of <i>X.laevis</i>. Xenopus-noid is expected to be a useful tool to understand the relationship between knee extension of frogs and swimming performance.</p>

• Decentralized Control Mechanism Underlying Scaffold-based Locomotion of Ophiuroids

  ONO Tatsuya, KANO Takeshi, AONUMA Hitoshi, MATSUZAKA Yoshiya, ISHIGURO Akio

  <p>Robots are now required to adapt to changes in the environments and physical damages so that they can work under harsh environments. To meet the requirement, we focused on ophiuroid' s highly adaptive and resilient locomotion. In our previous work, we proposed a decentralized control scheme for the well-balanced coupling between inter- and intra-limb coordination, using local force feedback. However, this scheme could not reproduce an avoidance behavior observed when arms detect reaction forces that impede propulsion. To tackle this problem, in this study, we redesigned a decentralized control scheme based on " TEGOTAE ", a Japanese concept describing how well a perceived reaction matches an expectation.</p>

• 2A2-S02 Decentralized Control Mechanism of Ophiuroid Locomotion by Exploiting "TEGOTAE" from Environment

  ONO Tatsuya, KANO Takeshi, AONUMA Hitoshi, MATSUZAKA Yoshiya, ISHIGURO Akio

  Although numerous robots have been developed inspired by animal locomotion, they could not reproduce adaptive and resilient behavior of real animals. To tackle this problem, we adopted ophiuroids as our model. In our previous work, we focused on the locomotion of an ophiuroid whose arms were shortened or removed to investigate the inter-arm coordination mechanism, and proposed a decentralized control scheme on the basis of "TEGOTAE", a Japanese word that means reaction after the generation of some action. In this study, we proposed a decentralized control scheme that enables well-balanced coupling between inter- and intra-limb coordination by extending our previous control scheme. The validity of the proposed control scheme was confirmed via simulation.

• Response of the Bioelectric Potential within Antenna of Mamestra Brassicae against Sex Pheromone

  KOBAYASHI Mitsuru, KATAOKA Takashi, AONUMA Hitoshi, SHIBATA Youichi

  <p>When a male moth perceives sex pheromone of a female moth, the bioelectric potential is generated in its antennas. This paper discusses putative novel methods controlling moths by using antennal ability that senses sex pheromone of <i>Mamestra brassicae </i>for the insect control. Measuring bioelectric potential, the antenna was cut off from the head and connected to the measurement instrument by electro-encephalogram paste. The maximum lifetime of after cutting off was approximate 200 minutes. The period of interstimulus interval to avoid sensory habituation was determined and it was more than 5 seconds. The Results showed that the bioelectric potential increased according to concentration of (<i>Z</i>)-11-hexadecenylacetate which is a principal ingredient of the sex pheromone. The relationship between the concentration of (<i>Z</i>)-11-hexadecenylacetate and the response of bioelectric potential was formulated by the approximate curve. It was concluded that the emergence of the female moth would be estimated by the response of bioelectric potential in the antenna against the sex pheromone.</p>

  Generation of adaptive swimming locomotion of Xenopus laevis is greatly affected by hydrodynamic interaction between its musculoskeletal system and water environments. To understand the mechanism of frog locomotion, it is a proper approach to build a hybrid musculoskeletal robot that has similar structure as a Xenopus laevis, and excite living muscles to drive the body like in vivo. We developed a swimming robot that had a similar musculoskeletal structure as a frog driven by living muscles. At first, we built musculoskeletal structure of the hind leg by a 3D printer copying the anatomy of Xenopus laevis. Then, we developed the swimming robot by driven the gastrocnemius muscles, realized kick motion that generated propulsion for swimming locomotion. And also, we checked that the robot's motion is similar to Xenopus laevis's one. Thus, to achieve to understand the swimming locomotion, the robot is expected to be a useful tool.

  Most robots are vulnerable to changes in their own morphology such as failures. To tackle this problem, we have focused on ophiuroids, which have simple body with pentaradial symmetry, as our model. Although they are composed of primitive decentralized nervous system, they can coordinate their arm movements adequately even when the arms are arbitrarily cut off. In this study, we aimed to clarify the fundamental mechanism underlying this resilient ophiuroid locomotion. For this purpose, we performed behavioral experiment using ohiuroids with different number of shortened arms, and proposed a simple autonomous decentralized control scheme on this basis. The validity of the propose control scheme was confirmed via simulation.

  Most robots are vulnerable to the change in their own morphology such as failures. To tackle this problem, we focus on ophiuroids, which have simple body with pentaradial symmetry. Although they are composed of primitive decentralized nervous system, they can move by self-organizing their arm movements adequately even when the arms are arbitrarily cut off. As a first step, we concentrate on an ophiuroid with one arm and aim to clarify its locomotion mechanism. We propose a simple autonomous decentralized control scheme on the basis of behavioral experiments, and confirm its validity via simulations.

  This paper describes our trials of active interactions to the crickets by a micro mobile robot for attracting pheromone behaviors. Cricket Gyllus bimaculatus modifies its own behavior based on the experiences based on the pheromone interactions between the individuals. For active interaction experiments, the micro mobile robot is maneuvered by an operator via the computer and the partial body of the cricket is attached to the robot. In this report, we describe interaction experimental results between the cricket and micro mobile robot with the pheromone. The cricket shows different response to the male or female pheromone, respectively. The result shows this approach could contribute to the biology as a novel one from the viewpoint of setting up the experimental conditions of the interactions actively.

• 1C1-6 Social adaptive modulation of temporal discount factor in Multi-agent reinforcement learning : Self organizing social hierarchy and neuromodulator

  YANO Shiro, AONUMA Hitoshi, ASAMA Hajime

  In the field of reinforcement learning, researchers have focused a role and dynamics of animal's neuromodulatory system, which is thought to correspond to meta-parameter of the learning system. Recently, the hypothesis is suggested and beginning to be verified that neuromodulator serotonin regulates the temporal discount factor. It is known that dominance hierarchy affects the amount of serotonin in animal society. It is also known that social hierarchy is generated from competitive behavior in a self-organizing manner. In this study, we propose self-organizing multi-agent reinforcement system which grows various temporal discount factors robust and fault-tolerant system. We show that this system has the capability adapting to environmental variability and robustness for vacancy or increasing of agents.

  An insect generates an environmental adaptive behavior by a small brain. The authors think that such ability for environmental adaptation brings useful knowledge for behavior control of a multi-robot system. Therefore, ability for environmental adaptation of a cricket was modeled as a behavior selection model. Such ability for environmental adaptation of insects is not yet elucidated enough. Therefore, in this study, the authors discuss about an engineering application of proposed cricket's behavior selection model. In particular about this paper, proposed model was discussed and compared with other behavior selection model efficiency as an example in sweeping task.

  FUNATO Tetsuro, Nara Masahito, Kurabayashi Daisuke, Aonuma Hitoshi, Ashikaga Masatoshi

  Crickets have a fixed habit to avoid the fighting for a certain minutes after their defeat. If the fighting opportunity is too frequent, some crickets cannot recover the militancy, which limits the number of fighting crickets depending on their group density. This phenomenon shows the property of crickets as an autonomous system that adapts to the density variation, i.e., environmental change, only by a local interaction. In this research, the mechanism of such a biological adaptability is discussed from the viewpoint of brain function. The behaviour selector is modelled using oscillator ne...

  In this paper, we propose a model of foraging behavior in multiple mobile robots. In this model, robots select behavior using their activities, which adjusted by interaction between other robots. And this model is using a mechanism of fighting behavior in male crickets. We simulate this model, and which shows that this model is better than a model of multiple robots without their activities about the working efficiency at dynamical working space.

  Recent physiological research has revealed the importance of neuromodulator (e.g. NO) in the pheromone behavior such as fighting behavior in insects. This research aims to model the function of neuromodulator in fighting behavior of crickets, and to emerge adaptive action selection by constructive approach. In this report, we assume a model for adaptive behavior selection by NO/cGMP cascade according to the physiological knowledge, and run some computer simulations.

• Intercellular synchronization of intracellular Ca^<2+> oscillation in cultured cardiac myocytes.

  NAKAYAMA Yukako, KAWAHARA Koichi, AONUMA Hitoshi, YAMAUCHI Yoshiko, NAKAJIMA Takayuki, HACHIRO Takeru

  Cultured cardiac myocytes from neonatal rats show spontaneous and cyclic contractions. The intracellular concentration of free Ca^<2+> also changes cyclically associated with the rhythmic contraction of myocytes (Ca^<2+> oscillation). This study aims at elucidating the mechanisms responsible for the intercellular synchronization of intracellular Ca^<2+> oscillation in cultured cardiac myocytes. In cultures at 4 days in vitro (4 DIV), Ca^<2+> oscillation was synchronized among myocytes in an aggregate. The oscillation was also synchronized between the myocytes in an aggregate and a remote my...

  Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (S), Grant-in-Aid for Scientific Research (S), Osaka University, 31 May 2017 - 31 Mar. 2022

  In this study, we proposed a methodology for obtaining zombie crickets that specifically and pharmacologically inhibit the function of crickets in the cranial nerve system. This zombie cricket has minimal cranial nerve function embedded in it for gait. Therefore, we sought a mathematical model of the control structure that causes the zombie cricket to walk in various places by external stimuli and produces the gait changes that may exist in the interaction of the brain, body, and environment at that time. , Tested that hypothesis with an incompetent robot.

  In this study, we aimed to elucidate how antenna fencing, a characteristic and interesting behavior observed in fighting behavior between male crickets, contributes to fighting behavior. In particular, we inserted electrodes into the muscles that move the antennas and electrically stimulated the antennas to perform fighting behaviors with external intervention. The results of the experiments suggested that the external intervention enhanced the fighting behavior of the crickets in the antenna fencing.

  Current artificial systems have difficulty in adapting to their physical damages and changes in the environment. To address this issue, we focused on brittle stars which can occasionally lose some of their arms and promptly coordinate the remaining arms to escape from predators, and aimed to elucidate the control mechanism underlying their resilient locomotion through behavioral experiments, mathematical modeling, and robot experiments. Specifically, we observed the way of inter- and intra-arm coordination during the locomotion of brittle stars whose arms were partially removed, and proposed a mathematical model on this basis. The proposed model was validated by real-world experiments with a brittle star-like robot developed. We also performed behavioral experiments in which circumoral nerve ring was partially transected, and clarified the mechanism for the determination of moving direction.


• Decoding Flexibility of Motor Control by Studying Amphibious Locomoion

  Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (A), Grant-in-Aid for Scientific Research (A), Tohoku University, 01 Apr. 2016 - 31 Mar. 2020

  Amphibious animals traverse different environmental media by flexibly changing the coordination of body movements. However, the neural mechanisms underlying flexible motor control in amphibious locomotion remain elusive. Here, we focused on a centipede (Scolopendra subspinipes mutilans) and explore the interplay between central and peripheral control mechanisms during transition between walking on land and swimming in water. Based on the findings obtained through behavioral experiments, we hypothesized that walking or swimming signals generated in the brain are sent posteriorly via distributed neural networks belonging to the central nervous systems and located along the body; these brain signals, can be overridden by sensory signals felt by the peripheral nervous system of the legs when they touch the ground during waling. We described this mechanism mathematically, and well reproduced the behavior of centipedes in different situations through computer simulations.

  This study aims to elucidate the interlimb coordination mechanism in adaptive insect locomotion with the intervention method into walking by using prosthetic legs. To this end, at the first fiscal year, we developed a simultaneous recording system of leg motions and leg muscle electromyography (EMG) by using high-speed camera and EMG amplifier. Then, using the developed system, we simultaneously measured leg motions and muscle activities in cricket walking before and after leg amputation. By analyzing the obtained data in 5 female crickets, we found that muscle activation timings of the both middle legs tend to be in-phase synchronization pattern from anti-phase synchronization pattern according to the “amount” of remaining leg parts. In the final fiscal year, we conducted a preliminary prosthetic experiments, suggesting that gait patterns were “reproduced” with the prosthetic legs even after leg amputation.


• Predicting spatio-/temporal-variation of parasite-mediated energy flow by revealing neural mechanisms of host manipulation by nematomorph parasites

  Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Challenging Exploratory Research, Grant-in-Aid for Challenging Exploratory Research, Kobe University, 01 Apr. 2015 - 31 Mar. 2017

  Nematomorph parasites indirectly strengthen energy flow through ecosystems via behavioral manipulation of their terrestrial hosts. However, neural mechanisms underlying this behavioral manipulation by the nematomorphs have not yet been clarified, which is making us difficult to predict the temporal-/spatial- variations of the parasite-mediated energy flow. To bridge the gaps between ecological and neuro-ethological knowledge about host manipulations, we examined behavior and brain biogenic monoamine levels in two Mantodea species parasitized by the nematomorphs to elucidate the neural mechanisms of the nematomorphs’ host manipulation. Overall, the locomotion activities of mantis harboring mature nematomorphs tended to be high irrespective of time of the day. In the parasitized mantis, dopamine and octopamine levels in the brain tended to be higher than those in the un-parasitized one, which might be one of the neural mechanisms of the behavioral manipulation by the nematomorphs.

  The subject of this research is the investigations for understating the mating behavior of the crickets by integrated approach with the robotics and neurophysiology. In this research, we developed an interaction system in the same scale with the cricket by utilizing a mobile robot that can realize the pheromone and the song presentation. By the pheromone interaction experiments with developed robot's behavior algorithm, the understanding to the mating behavior of the cricket was deepened. Sound source localization behavior was also observed by the experiments with the devices that can play recorded calling song arbitrary. The changes of the biogenic amine in the cricket's brain by pheromone stimuli and its homeostatic characteristics were investigated. W also investigated how the biogenic amines in the crickets' s brain respond to the calling song of the crickets.


• Toward realization of resilient behavior inspired by ophiuroid locomotion

  Most robots are vulnerable to changes in environment and their own morphology such as failures. To overcome this problem, we drew inspiration from an ophiuroid, which is a primitive living organism. An ophiuroid, which consists of a central disc and five functionally interchangeable arms that diverge radially from the central disc, can move away from predators or harmful stimuli by autotomizing its arms. Very interestingly, an ophiuroid can maintain locomotion after losing its arms arbitrarily. In this study, we modeled the control principle underlying this resilient behavior. We showed that a simple decentralized control scheme could well reproduce that behavior by performing numerical simulations as well as experiments with real physical ophiuroid-like robots.

  The aim of this project is understanding the neuronal mechanisms underlying adaptive behavior, and we focused on mating behavior that is one of the common behaviors of animals. In crickets, males sound calling song and courtship song to attract a female. The female can decide to mate or not to mate with the male sounding. In order to understand the neuronal mechanism of mating selection, we have investigated the roles of biogenic amines, in particular dopamine (DA). Behavioral and pharmacological experiments demonstrated that metabolism of DA in the brain increased when female respond to the calling song. We then asked which neurons release or receive DA in the brain? In order to identify these neurons, we challenged to develop novel method to create transgenic crickets (in vivo RMCE). As a first step, we succeeded in creating transgenic crickets carring attP sequence. Using them, we have challenged to create transgenic crickets using phiC31 integrase.

  We focused on the aggressive behavior between male crickets to understand how animals alter their behaviors on the demand of changing circumstances. Biogenic amines modulate motivation of many kinds of behaviors. In our behavior and pharmacological studies demonstrate that octopamine in the brain initiates aggressive motivation in the cricket. In order to get better understand, we have been developing transgenic technique to manipulate octopaminergic system in the brain. We identified biogenic amine related genes including octopamine, serotonin, dopamine and tyramine. We also developed some tools for genetic approaches. We also developed micro robot system to manipulate cricket aggressive behavior. This system makes us perform electrophysiological experiment using free moving animal with predicting the result of fight between male crickets.

  For active interaction with the cricket, we constructed a system with real-time recording of the behavior and on-line control of micro-mobile robot. We also implemented control algorithm inspired by the interaction behavior of the cricket and confirmed that adaptive behavior switching was emerged by the interactions utilizing the robot. In order to elucidate how crickets change motivation for mating and aggression, we investigated change in the level of brain amines and found that change in dopamine level links with mating behavior and that change in octopamine level links with aggression.

  In the pond snail Lymnaea stagnalis, the neural circuitry underlying feeding is well described. I here studied the insulin-regulated mechanism affecting feeding behavior in the central nervous system (CNS) of Lymnaea. First, I examined the gene expression of molluscan insulin-related peptide II(MIPII) in the CNS. As a result, several days of hunger or satiation did not have effects on gene expression of MIPII. More, the feeding response to sucrose did not correlate to MIPII gene expression. Next, I examined to identify the neurons that respond to insulin or sucrose application to animals. The neurons that respond to those stimuli were in the buccal ganglia that contain the neural circuitry for feeding.

  We have investigated the design principle of neuronal mechanisms for social adaptation in animals, by focusing on how animals determine their behavior depending on previous social experiments. We focused on cricket agonistic behavior that is released by cuticle pheromones. We are to reveal behavioral and physiological aspects of socially adaptive behaviors. Nitric oxide system and octopamine system in the central nervous system could mediate aggressive behavior of the crickets. Based on our experimental results, we establish dynamic behavior models and neurophysiological models. We found one of important structure that maintains social adaptive behaviors, that is multiple feedback structure which is composed of feedback loop in nervous systems and through social interactions.

  受精卵は卵割を繰り返して単細胞から多細胞へと移行する。受精卵の卵割を、単細胞生物から多細胞へと移行した進化過程のモデルとして扱い、多細胞化が、単細胞に比べて、熱雑音に埋もれた微弱な観測信号の信頼性(情報量)を加算平均化によって改善していることを実証する。これまでに、コオロギの気流感覚細胞は分子1個の平均運動エネルギー【approximately equal】k_BT(常温で約4×10〜<-21>Joule)に応答できることを実測し、この熱雑音感受性が神経系の基本構造である並列伝送回路の起源であることを示した。ここで重要なのは、単一分子の熱揺動エネルギーを検出する程の高感度は進化の結果ではなく拘束である、という結論にある。その根拠は、もし細胞がかって低かった感度を上げてk_BT領域に近づいたのなら、自ら熱雑音の中に埋もれて行ったことになり、観測装置としての自殺行為に他ならないからである。時間的空間的に偏った資源環境は、情報伝送速度を上げる向きの淘汰圧として働く。生命誕生前の原始のスープで利用可能なエネルギーは熱揺らぎ幅k_BTの程度であり、このk_BTの程度のエネルギー差を観測して情報(負のエントロピー)に変換する非平衡系が生命である。生命の起源にとって、k_BTの程度のエネルギー感度は必然である。細胞表面に複数のレセプター分子を並べることも加算平均化になる。観測装置としての細胞が複数結合した加算平均化が生存価を増す。多細胞生物への進化は、単細胞生物に比べて、熱雑音に埋もれた微弱な観測信号の信頼性(情報量)を加算平均化によって改善した例である、ことの情報理論的検証を目的とした。当初計画は、割球数の増加にともなう膜電位雑音の振幅減少の実測によって、加算平均原理を実証するものであった。しかし膜電位雑音の計測は不安定で卵割前後の比較が困難であった。また代替法として試みた膜電位固定下での電流雑音の計測も不調に終わった。このため、多細胞化の熱雑音仮説の実証は達成できなかったが、その情報論的考察の拡張に寄与した。

  動物が状況に応じて適切に行動を選択し発現する神経生理機構の解明を目指してきた.一酸化窒素(NO)は神経伝達の修飾機構に関与するばかりではく,学習や記憶の基盤となる神経の可塑性に重要な役割を担う生理活性物質である.行動の切り換えや発現の神経生理機構においてNO/cGMPシグナルの中枢神経系での役割について昆虫をモデル動物として行動学実験,薬理学実験,生化学実験を行った. コオロギの喧嘩行動の切り換えと発現機構にはNO/cGMPカスケードが関与することが薬理行動学実験から明らかになってきた.そこで,NOの脳内発現機構を調べる第一段階として,コオロギのNO合成酵素mRNAの塩基配列を部分配列を決定し結果をGenBankに登録した(AB245472).この結果を基にin situ hybridization法によりNOS細胞の局在を調査中である. また,行動学的な実験では,行動履歴が行動発現にいかに関与するのかを雌雄の行動パタンを比較しながら検討してきた.これまで,オスのコオロギの喧嘩行動については多くの研究者が研究を行ってきたが,メス同士の喧嘩行動についてはよく知られていなかった.今回,メスのコオロギ同士も,オス同様に喧嘩をすることが行動学実験から証明することができた.オスのコオロギは相手の体表物質によって喧嘩行動を解発するが,メスでは別の信号が鍵刺激になることが示唆された.さらに,喧嘩行動のパタンはオスと類似することから,喧嘩を発現する脳内回路はオスとメスでは共有していると考えられ,今後は,その神経回路がいかに選択されて行動が発現するかを調べる必要が生じた.

  Why nerves are bundles of a large number of fibers? Is this a simple consequence of multi-cellular organization of metazoan life? This naive question will reaches, in the end, what type of selection pressure the nervous system was adaptive to or gaining a survival value in the evolution? and also what kind of constraints has been tied on the adaptation?Acquisition of information (i.e. measurement) inevitably requires dissipation of energy (entropy in accurate). Energy cost of information in cricket wind receptor cell was measured as very close to the limit of thermodynamic theory (0.7 kBT Joule/bit). Results revealed by this research are followings.1) Optical measurement of the Brownian motion of the cricket wind receptor hair revealed the validity of fluctuation-dissipation theorem in living tissue.2) Cricket sensory cell is sensitive to thermal noise and therefore operates as a very poor informational element because of low signal to noise ratio.3) The present study confirmed that the principle of summation average, i.e. reliability of mean value depends on inverse square root of sample size, is effective principle in the nervous system where cells are largely stochastic because of thermal noise.The extremely high sensitivity of living cell to thermal noise is not achieved by evolution, but this is rather constraint retroactively to the beginning of life. Spatio-temporally uneven distribution of resource and harm in living environment act as selection pressure for increase in transmission rate of information. Biological solution by living cells which are tied on the constraint of poor signal to noise ratio is the summation average by parallel transmission.

• Analysis of the roles of NO-cGMP signaling cascade for long-term memory formation in an insect.

  Cyclic AMP pathway plays an essential role in formation of long-term memory (LTM). In some species, the nitric oxide (NO)-cyclic GMP pathway has been found to act in parallel and complementary to the cAMP pathway for LTM formation. The aim of this study was to clarify the roles of the NO-cGMP pathway for the LTM formation. We have studied the signaling cascade underlying LTM formation by systematically co-injecting various 'LTM-inducing' and 'LTM-blocking' drugs in crickets. Multiple-trial olfactory conditioning led to LTM that lasted for several days, while memory induced by single-trial conditioning decayed away within several hours. Injection of inhibitors of the enzyme forming NO, cGMP or cAMP into the hemolymph prior to multiple-trial conditioning blocked LTM, whereas injection of an NO donor, cGMP analogue or cAMP analogue prior to single-trial conditioning induced LTM. Induction of LTM by injection of an NO donor or cGMP analogue paired with single-trial conditioning was blocked by inhibitors of the cAMP pathway, but induction of LTM by a cAMP analogue was unaffected by inhibitors of the NO-cGMP pathway. Inhibitors of cyclic nucleotide gated channel (CNG channel) or calmodulin blocked induction of LTM by cGMP analogue paired with single-trial conditioning, but they did not affect induction of LTM by cAMP analogue. This study suggests, for the first time, that the cAMP pathway is a downstream target of the NO-cGMP pathway for the formation of LTM and that the CNG channel and calcium-calmodulin intervene between the NO-cGMP pathway and the cAMP pathway.

  動物は、環境への適応機構のひとつとして神経系を進化の過程で獲得した。刻々と変化する状況に即して動物は様々な行動を発現し、外部環境の変化に適応している。では、動物は状況に応じてどの様な神経生理機構で適切な行動を発現し、切替えているのか?本研究では、いかに状況に応じた行動が発現されるのかその神経機構を理解しようとしている。神経の可塑的な性質は行動を切り換える際に必要な生理機構である。この様な神経の可塑的な変化には一酸化窒素(NO)が重要な役割を担っていると考え、節足動物、特にザリガニやコオロギを実験材料として、同定可能な神経回路網においてNOがどの様な修飾効果をもつのか細胞レベルでの詳細な解析を進めるとともに、行動レベルでの効果、役割を解析してきた。その成果として、1.組織化学染色法でNO産生細胞と標的細胞の局在をこれまでに確かめ、さらに、昆虫の脳では常にNOが100-200nM程度放出されていること、刺激により更に放出量が増加することを電極法で計測し示した。2.NOの光学的な計測を行い、中枢神経系の中でどの程度の一酸化窒素が産生されているのか突き止めるため、既存の共焦点レーザー走査顕微鏡を改造するため備品としてレーザー光源ユニットを購入し、NO感受性色素を使って光学的に解析を続けている。3.電気生理学的にNO産生細胞と標的細胞の両方の細胞から活動を計測し、一酸化窒素やcGMPの合成を促進或いは抑制する薬物を灌流投与し、一酸化窒素の修飾効果を解析し、神経系におけるNOの修飾効果を示した。これまでの成果は国際シンポジウム及び国内学会で発表し、また、その一部は既に国際学会誌等に論文として発表し、残りの成果については現在発表の準備に取りかかっている。

  神経細胞は熱雑音感受性をもっており、そのことが神経系に共通する基本構造である並列伝送回路の起源であることを、1.神経細胞は情報受容に当たってエネルギーを散逸する抵抗体として動作し、揺動散逸定理に従ったブラウン運動を観察できること、2.異なる細胞のブラウン運動は互いに無相関であること、3.感覚細胞がブラウン運動を用いて確率サンプリングした信号は介在神経でシナプス加算によって再構成されること、を実証するため研究を進めてきた。コオロギ気流感覚毛の機械特性の計測から感覚閾値で感覚細胞が受け取るエネルギーが常温における分子1個の熱揺動エネルギーk_BTに近いこと、閾値付近の刺激に対する応答発火揺らぎの解析から感覚細胞は内部の熱雑音源をパルス符号化に用いるStochastic Samplingで中枢へ信号を送っていること、感覚細胞の情報伝送容量の測定から、信号対雑音比は0.1程度と非常に低いこと、このため情報伝送素子としての細胞1個の性能は400ビット/秒程度に制限されている。これまでの研究で、気流感覚毛先端のブラウン運動が10nm程度であることを予想して、光学顕微鏡を改造し感覚毛のレーザー照明強拡大像(900倍)を4分割受光素子上に結ばせたブラウン運動計測装置(分解能3nmでの計測が可能)を実用化(平成12年度基盤研究(B)で製作)し、コオロギ気流感覚毛のブラウン運動を光学的に測定した。現在引き続き、2本の気流感覚毛のブラウン運動を同時計測し、近傍のものでも感覚細胞は互いに無相関な熱雑音に曝されていることを実証すべく解析を続けている。

  Mechanoreception is a fundamental element of animal-environment interaction and it is essential for the understanding of animal evolution. Mechanoreception has mainly been considered by a rather simple and macroscopic scheme of ionic channels deformed by membrane tension. Enormous high-sensitivities of mechanoreceptors have been reported in the eardrums of human and lacewing as 0.1 Angstrom i.e. one-tenth of a hydrogen atom diameter. It is obviously erroneous, however, to express the sensitivity of mechanical detector by displacement. Sensory cell is a measurement tool that converts external energy to informational entropy. The sensitivity must be discussed in terms of energy. All sensory cells receive a certain amount of energy, because any measurement without energy cost results in the thermodynamic inconsistency of Maxwell's demon. Energy threshold of the wind sensory cells in cricket is measured as very small values about 4×10^<-21> [Joule]. These mechanoreceptors would give rise a response shaken by Brownian motion of a single molecule.Pathway of conversion from mechanical energy to cellular response, particularly of its initial process is still beyond our comprehension. In order to reveal its cellular mechanisms, a direct measurement of membrane current in response to the extremely weak mechanical stimuli near Brownian motion is attempted.The receptor current was measured through a voltage clamp electrode, which also gives displacement to hair shaft. Shaft of a 1000 m long hair is clipped at 100 m to have electrical conduction through the hollow of hair shaft. Amount of energy estimated for the electrical current in response to 10-100 nm displacement at 100 m clipped shaft showed an energy amplification of about 10^6 times when compared to the mechanical energy given as the stimulus. The result suggests that the open-close of ionic channels is not a direct initial process of energy transduction in the mechanoreceptor cell.

  昆虫の機械受容器は、常温の熱揺動エネルギーk_BT(約4×10^<-21>J、可視光フォトンのエネルギーの1/100)をも検出できる最高度に進化した刺激受容系である。コオロギ気流感覚細胞が熱雑音(ブラウン運動)に揺すられて発火するほど高感度なこと、中枢の介在神経は熱雑音の無相関性を利用して閾値以下の微弱な信号を抽出することを明らかにする目的で本プロジェクトを遂行した。フォトンのような量子を持たない機械受容器、化学受容器、イオンチャンネル、シナプス受容体などは必然的に熱雑音に出会うから、雑音揺らぎやシナプス加重機構が神経系一般に広くみられることなど、情報機械としての神経系が究極の乱数発生器としての熱雑音を利用する設計原理の解明につながる。コオロギを実験材料に、気流感覚器の機械的構造と感覚細胞のエネルギー変換応答とを分離し、分子熱雑音限界までエネルギー感度を進化させた機械感覚細胞の刺激受容機構解明の手がかりを得、情報機械としての感覚細胞の性質を解明するため感覚細胞が運ぶ情報、感覚細胞が介在神経に伝える情報量の定量化を試みた。中枢の介在神経から記録をとり、閾値付近の気流刺激への応答から、感覚細胞から介在神経への情報伝送量を測定した。コオロギの気流感覚細胞が運ぶ情報量はスパイク1つ当たり2〜4bit。入力感覚繊維1本あたりの情報量はおよそ300bits/secであることを示した。また、中枢の気流感覚介在神経の樹状突起部から細胞内記録をとり、閾値付近の人口白色雑音波形を繰り返し与え、後シナプス集合電位の変動分から、気流から介在神経までの情報伝送量(bits/sec)を測定した結果、50〜200bits/sec程度とばらつきはあるが1個の感覚細胞が伝える情報量より遥かに小さいことがわかった。昆虫の機械受容器は究極感度まで進化し熱雑音に直面している、逆説的に熱雑音のエネルギーと無相関性を利用してさらに微弱な信号を検出する中枢機構が進化したことが示唆された。
