  English, Scientific journal, ABSTRACT
  
  Non‐spiking neurons use graded potentials for processing neural information, unlike spiking neurons. These non‐spiking neurons struggle to transmit signals distally due to membrane potential decay. Consequently, they possibly perform unique computations different from spiking neurons by using local processing with graded potential. Invertebrates, such as insects, possess both non‐spiking and spiking neurons in their central nervous system. However, how the subcellular local regions in non‐spiking neurons process sensory information remains unclear. We examined intracellular Ca ²⁺ dynamics in the wind‐sensitive non‐spiking neurons of crickets. Directional information about airflow is processed by a local circuit within the terminal abdominal ganglion, where several identified non‐spiking interneurons are involved. In this study, we measured the membrane potential and Ca ²⁺ responses to airflow from different angles in three local non‐spiking interneurons. These neurons exhibited spatial heterogeneities in their Ca ²⁺ responses. In two non‐spiking interneurons, the similarity in the time course of Ca ²⁺ responses between subcellular regions decreased with increasing intracellular distance. However, the similarity in directional selectivity was not always linked to the intracellular distance. In addition, the Ca ²⁺ signals induced by current injection did not necessarily couple with the membrane potential changes. The temporal dynamics of Ca ²⁺ signals were possibly influenced by partially uneven electrical propagation, and their directional selectivity, primarily determined by the spatial presynaptic arrangement, might depend less on intracellular distance. Therefore, local non‐spiking interneurons likely perform local processing affected by both presynaptic and postsynaptic factors, enabling a single neuron to substitute for functions otherwise distributed across multiple spiking neurons., 42296296;34279242

  English, Scientific journal, Animals, including insects, change their innate escape behavior triggered by a specific threat stimulus depending on the environmental context to survive adaptively the predators’ attack. This indicates that additional inputs from sensory organs of different modalities indicating surrounding conditions could affect the neuronal circuit responsible for the escape behavior. Field crickets, Gryllus bimaculatus, exhibit an oriented running or jumping escape in response to short air puff detected by the abdominal mechanosensory organ called cerci. Crickets also receive a high-frequency acoustic stimulus by their tympanal organs on their frontal legs, which suggests approaching bats as a predator. We have reported that the crickets modulate their wind-elicited escape running in the moving direction when they are exposed to an acoustic stimulus preceded by the air puff. However, it remains unclear how long the effects of auditory inputs indicating surrounding contexts last after the sound is terminated. In this study, we applied a short pulse (200 ms) of 15-kHz pure tone to the crickets in various intervals before the air-puff stimulus. The sound given 200 or 1000 ms before the air puff biased the wind-elicited escape running backward, like the previous studies using the longer and overlapped sound. But the sounds that started 2000 ms before and simultaneously with the air puff had little effect. In addition, the jumping probability was higher only when the delay of air puff to the sound was 1000 ms. These results suggest that the cricket could retain the auditory memory for at least one second and alter the motion choice and direction of the wind-elicited escape behavior., 42296296;34279242;12825301

  English, Scientific journal, The structures of neurons, such as dendrites and axonal projections, are closely related to their response properties and their specific functions in neural circuits. Identified neurons, having genetically determined morphological features and pre- and postsynaptic partners, play significant roles in specific behaviors. Giant interneurons (GIs) are identified in the terminal abdominal ganglion of the cricket as mechanosensory projection neurons and are sensitive to airflow stimulation of the cerci. GIs are classified into ventral GIs (vGIs) or dorsal GIs (dGIs) depending on the location of their axons running within the connective nerve cord. Based on their response properties to airflow, vGIs are presumed to be involved in triggering the wind-elicited escape response, whereas dGIs are thought to be airflow direction-encoding neurons. The previous findings regarding airflow sensitivity point to possible differences in the morphology of the central projections that may correspond to their neural functions. However, the detailed morphologies of the GIs in the cephalic and thoracic ganglia of adult crickets remain unclear. In this study, we stained six GIs, namely, GI 8-1 (medial giant interneuron, MGI), 9-1 (lateral giant interneuron, LGI), 9-2, 9-3, 10-2, and 10-3, using intracellular iontophoretic or pressure injection of dyes. Staining revealed remarkable differences in the axonal branching patterns between vGIs and dGIs. The dGIs were further divided into subgroups based on the profiles of their axon collaterals and projection sites in the brain. The anatomical differences between the GIs' central projections seemed to be related to their information encodement and behavioral functions., 34279242;12825301

  English, Scientific journal, To survive a predator's attack, prey animals must exhibit escape responses that are appropriately regulated in terms of their moving speed, distance, and direction. Insect locomotion is considered to be controlled by an interaction between the brain, which is involved in behavioral decision-making, and the thoracic ganglia (TG), which are primary motor centers. However, it remains unknown which descending and ascending signals between these neural centers are involved in the regulation of the escape behavior. We addressed the distinct roles of the brain and TG in the wind-elicited escape behavior of crickets by assessing the effects of partial ablation of the intersegmental communications on escape responses. We unilaterally cut the ventral nerve cord (VNC) at different locations, between the brain and TG, or between the TG and terminal abdominal ganglion (TAG), a primary sensory center of the cercal system. The partial ablation of ascending signals to the brain greatly reduced the jumping response rather than running, indicating that sensory information processing in the brain is essential for the choice of escape responses. The ablation of descending signals from the brain to the TG impaired locomotor performance and directional control of the escape responses, suggesting that locomotion in the escape behavior largely depends on the descending signals from the brain. Finally, the extracellular recording from the cervical VNC indicated a difference in the descending activities preceding the escape responses between running and jumping. Our results demonstrated that the brain sends the descending signals encoding the behavioral choice and locomotor regulation to the TG, while the TG seem to have other specific roles, such as in the preparation of escape movement., 12825301

  English, Scientific journal, Animals perceive their surroundings by using various modalities of sensory inputs to guide their locomotion. Nocturnal insects such as crickets use mechanosensory inputs mediated by their antennae to orient in darkness. Spatial information is acquired via voluntary antennal contacts with surrounding objects, but it remains unclear whether the insects modulate behaviors mediated by other sensory organs based on that information. Crickets exhibit escape behavior in response to a short air-puff, which is detected by the abdominal mechanosensory organs called cerci and is perceived as a “predator approach” signal. We placed objects of different shapes at different locations with which the cricket actively made contact using its antenna. We then examined the effects on wind-elicited escape behavior. The crickets changed their movement trajectory in response to nearby objects like walls so that they could avoid collision with these obstacles even during the cercal-mediated behavior. For instance, when a wall was placed in front of the crickets so that it was detected by one antenna, the escape trajectory in response to a stimulus from behind was significantly biased toward the side opposite the wall. Even when the antenna on the free side without the wall was ablated, this collision avoidance was also observed, suggesting that the mechanosensory inputs from one antenna detecting an object edge would be sufficient to perceive the location of obstacle in front. This study demonstrated that crickets were able to use the spatial information acquired with their antennal system to modify their behavior mediated by other sensory organs., 12825301;34279491

  English, Scientific journal, Insects have a sophisticated ability to navigate real environments. Virtual reality (VR) is a powerful tool for analyzing animal navigation in laboratory studies and is the most successful when used in the study of visually guided behaviors. However, the use of VR with non-visual sensory information, such as sound, on which nocturnal insects rely, for analyzing animal navigation has not been fully studied. We developed an auditory VR for the study of auditory navigation in crickets, Gryllus bimaculatus. The system consisted of a spherical treadmill on which a tethered female cricket walked. Sixteen speakers were placed around the cricket for auditory stimuli. The two optical mice attached to the treadmill measured the cricket’s locomotion, and the sound pressure and direction of the auditory stimuli were controlled at 100 Hz based on the position and heading of the cricket relative to a sound source in a virtual arena. We demonstrated that tethered female crickets selectively responded to the conspecific male calling song and localized the sound source in a virtual arena, which was similar to the behavior of freely walking crickets. Further combinations of our system with neurophysiological techniques will help understand the neural mechanisms for insect auditory navigation., 12825301

  English, Scientific journal, A comparative analysis of animal behavior (e.g., male vs. female groups) has been widely used to elucidate behavior specific to one group since pre-Darwinian times. However, big data generated by new sensing technologies, e.g., GPS, makes it difficult for them to contrast group differences manually. This study introduces DeepHL, a deep learning-assisted platform for the comparative analysis of animal movement data, i.e., trajectories. This software uses a deep neural network based on an attention mechanism to automatically detect segments in trajectories that are characteristic of one group. It then highlights these segments in visualized trajectories, enabling biologists to focus on these segments, and helps them reveal the underlying meaning of the highlighted segments to facilitate formulating new hypotheses. We tested the platform on a variety of trajectories of worms, insects, mice, bears, and seabirds across a scale from millimeters to hundreds of kilometers, revealing new movement features of these animals., 12825301
• Internal state transition to switch behavioral strategies in cricket phonotaxis behavior

  English, Scientific journal, Animals employ multiple behavioral strategies for exploring food and mating partners based on both their internal state and external environment. Here, we examined how cricket phonotaxis, which was considered an innate reactive behavior of females to approach the calling song of conspecific males, depended on these internal and external conditions. Our observation revealed that the phonotaxis process consisted of two distinctive phases: wandering and approaching. In the latter phase, crickets moved directly towards the sound source. The transition into this phase, referred to as the ‘approach phase’, was based on changes in the animal's internal state. Moreover, retention of the approach phase required recognition of the calling song, while song loss downregulated cricket mobility and induced frequent stopping. This is a typical movement in local search behaviors. Our results indicate that phonotaxis is not only a reactive response but a complicated process including multiple behavioral strategies., 12825301
• Trade-off between motor performance and behavioural flexibility in the action selection of cricket escape behaviour.

  English, Scientific journal, To survive a predator's attack successfully, animals choose appropriate actions from multiple escape responses. The motor performance of escape response governs successful survival, which implies that the action selection in escape behaviour is based on the trade-off between competing behavioural benefits. Thus, quantitative assessment of motor performance will shed light on the biological basis of decision-making. To explore the trade-off underlying the action selection, we focused on two distinct wind-elicited escape responses of crickets, running and jumping. We first hypothesized a trade-off between speed and directional accuracy. This hypothesis was rejected because crickets could control the escape direction in jumping as precisely as in running; further, jumping had advantages with regard to escape speed. Next, we assumed behavioural flexibility, including responsiveness to additional predator's attacks, as a benefit of running. The double stimulus experiment revealed that crickets running in the first response could respond more frequently to a second stimulus and control the movement direction more precisely compared to when they chose jumping for the first response. These data suggest that not only the motor performance but also the future adaptability of subsequent behaviours are considered as behavioural benefits, which may be used for choosing appropriate escape reactions., 12825301

• Multisensory enhancement of burst activity in an insect auditory neuron

  Journal of Neurophysiology, 120, 1, 139, 148, American Physiological Society, 01 Jul. 2018, [Peer-reviewed], [Last author, Corresponding author]
  English, Scientific journal, Detecting predators is crucial for survival. In insects, a few sensory interneurons receiving sensory input from a distinct receptive organ extract specific features informing the animal about approaching predators and mediate avoidance behaviors. Although integration of multiple sensory cues relevant to the predator enhances sensitivity and precision, it has not been established whether the sensory interneurons that act as predator detectors integrate multiple modalities of sensory inputs elicited by predators. Using intracellular recording techniques, we found that the cricket auditory neuron AN2, which is sensitive to the ultrasound-like echolocation calls of bats, responds to airflow stimuli transduced by the cercal organ, a mechanoreceptor in the abdomen. AN2 enhanced spike outputs in response to cross-modal stimuli combining sound with airflow, and the linearity of the summation of multisensory integration depended on the magnitude of the evoked response. The enhanced AN2 activity contained bursts, triggering avoidance behavior. Moreover, cross-modal stimuli elicited larger and longer lasting excitatory postsynaptic potentials (EPSP) than unimodal stimuli, which would result from a sublinear summation of EPSPs evoked respectively by sound or airflow. The persistence of EPSPs was correlated with the occurrence and structure of burst activity. Our findings indicate that AN2 integrates bimodal signals and that multisensory integration rather than unimodal stimulation alone more reliably generates bursting activity.
  
  NEW & NOTEWORTHY Crickets detect ultrasound with their tympanum and airflow with their cercal organ and process them as alert signals of predators. These sensory signals are integrated by auditory neuron AN2 in the early stages of sensory processing. Multisensory inputs from different sensory channels enhanced excitatory postsynaptic potentials to facilitate burst firing, which could trigger avoidance steering in flying crickets. Our results highlight the cellular basis of multisensory integration in AN2 and possible effects on escape behavior., 12825302

  English, Scientific journal, To determine the nature of intracellular Mg2+ stores and Mg2+ release mechanisms in differentiated PC12 cells, Mg2+ and Ca2+ mobilizations were measured simultaneously in living cells with KMG-104, a fluorescent Mg2+ indicator, and fura-2, respectively. Treatment with the mitochondrial uncoupler, carbonyl cyanide p-(trifluoromethoxy) phenylhydrazone (FCCP), increased both the intracellular Mg2+ concentration ([Mg2+]i) and the [Ca2+]i in these cells. Possible candidates as intracellular Mg2+ stores under these conditions include intracellular divalent cation binding sites, endoplasmic reticulum (ER), Mg-ATP and mitochondria. Given that no change in [Mg2+]i was induced by caffeine application, intracellular IP3 or Ca2+ liberated by photolysis, it appears that no Mg2+ release mechanism thus exists that is mediated via the action of Ca2+ on membrane-bound receptors in the ER or via the offloading of Mg2+ from binding sites as a result of the increased [Ca2+]i. FCCP treatment for 2 min did not alter the intracellular ATP content, indicating that Mg2+ was not released from Mg-ATP, at least in the first 2 min following exposure to FCCP. FCCP-induced [Mg2+]i increase was observed at mitochondria localized area, and vice versa. These results suggest that the mitochondria serve as the intracellular Mg2+ store in PC12 cell. Simultaneous measurements of [Ca2+]i and mitochondrial membrane potential, and also of [Ca2+]i and [Mg2+]i, revealed that the initial rise in [Mg2+]i followed that of mitochondrial depolarization for several seconds. These findings show that the source of Mg2+ in the FCCP-induced [Mg2+]i increase in PC12 cells is mitochondria, and that mitochondrial depolarization triggers the Mg2+ release.

• Active Properties of Dendrites in Identified Sensory Interneurons
  OGAWA Hiroto; OKA Kotaro, Biophysics, 45, 4, 198, 202, 25 Jul. 2005
  We examined dendritic activity in identified mechanosensory interneurons in the cricket cercal sensory system using Ca^<2+> imaging and intracellular recording techniques. Different dendritic branches of the interneurons displayed distinct directional sensitivity profiles to air-current stimuli. The amplitude of evoked spikes was larger at the dendritic branches in which the Ca^<2+> elevation was larger. Dual-site recordings of the dendritic spikes indicate that the spike-initiation site shifts depending on the location of the site of synaptic activation. We propose that a difference in spike-propagation direction could change the spike waveform at the distal dendrite and could produce synaptic activity-dependent Ca^<2+> dynamics., 日本生物物理学会, Japanese

  本年度は、次の2つの課題について研究を行った。
  1）コオロギ脳内ニューロンの気流応答性の解析：脳内のニューロンから細胞内電位記録を行い、気流刺激に対する反応特性を調べた。さらに記録した細胞の形態に基づいて、上行性ニューロン（AsNs）、局所介在ニューロン（LINs）、下行性ニューロン（DsNs）に分類し、さらにその神経突起の両側性／半側性を加味して細胞を分類した。まず気流刺激に対する反応潜時に注目したところ、半側性のLINの反応潜時は両側性のLINより短い傾向がみられた。したがって、最終腹部神経節から巨大介在ニューロン（Giant Interneurons, GIs）によって搬送される気流情報はまず半側性LINに入力されると考えられる。また、気流刺激に対する方向選択性について解析したところ、GIsを含むほとんどのAsNsは軸索側からの刺激に高い選好性を示す傾向が見られた。一方、LINsは方向選択性が弱く、後方からの刺激に選好性示すものが多かった。また、DsNsの選好方向や方向選択性の鋭さは細胞によって様々だった。LINの後方への選好性は，後方からの刺激に対する逃避行動閾値の低さに関連しているのかもしれない。また，DsNsの反応の多様さは，その下行性信号によって様々な運動を制御していることを反映している可能性がある。
  2）巨大介在ニューロンの上位中枢投射パターンの解析：６種のGIsの脳，食道下神経節，および前胸・中胸・後胸神経節における軸索投射形態を詳細に解析し，従来グループ分けされていた背側GIs（dGIs）と腹側GIs（vGIs）では中枢投射パターンが異なり，さらにvGIsは9-2,9-3と10-2,10-3のサブグループに分かれることがわかった。 この形態学的な違いはGIsが搬送する気流情報が異なり，刺激依存的な気流逃避行動の制御機構の基盤になっている可能性を示唆した。

  The Systems Science of Biological Navigation (International Activity Support Group) promoted international research activities by holding international competitions on navigation analysis methods, inviting young researchers to travel abroad, and inviting distinguished researchers to Japan. Specifically, with animal and human trajectory datasets made public, we held competitions on algorithms to understand behaviors from the trajectories. The winners of these competitions were invited to international symposiums and conferences hosted by this project, providing opportunities for young researchers and students to interact with each other. This exchange led to the establishment of a new international collaborative research network. In addition, tutorials and workshops were held at several international conferences to discuss the research of this group with overseas researchers.

  限定的な感覚遮断による隔離飼育と集団飼育における性行動の発達を比べてみると、性行動の発達には幼虫期の社会的経験が不可欠であるように見える。しかし、隔離によって雌の存在が雄の性行動のリリーサとして機能しなくなっても、羽化直後の社会的経験によって回復することがわかった。性行動の発達には、幼虫期の社会的経験だけでなく羽化後の社会的経験も関わっていると考えられる。社会的経験の構成要因には、触れ合いにともなう機械刺激や体表化学物質による化学刺激の関与が考えられるが、幼虫期の機械刺激のみで闘争行動が発達したのに対し、幼虫期の機械刺激や化学刺激はそれぞれ単独では性行動の発達要因とはなり得なかった。性行動の発達には、視覚をも含む感覚情報の整合性を満たすことが必要と考えられる。
  octopamineやserotoninなどの生体アミンは、昆虫の中枢や体液中に存在し行動の発現を調節する神経ホルモンとしてはたらいている。生体アミンによる行動発達調節の分子機構を明らかにするために、molecular targeting法(分子標的法)の開発を行った。その結果、細胞表面にoctopamine結合タンパク質を含む細胞を標的とする毒の作成に成功した。この神経毒をコオロギの腹腔中に注入した場合の行動発現への影響を調べたところ、注入後の時間経過と共に性行動の発現や攻撃性の低下が見られた。コオロギの行動の発達に関わる生体アミンの空間的、時間的調節のしくみを理解する上でmolecular targeting法が強力なツールになることが明らかになった。

  本研究は,昆虫の行動を制御する脳・神経機能の解明に向けて,行動下にある昆虫の脳神経節の神経活動を光学的に測定することを目的とする。本年度はフタホシコオロギ脳神経節のキノコ体傘部の神経活動をカルシウムイメージングによって計測することを具体的な研究課題とした。年度前半は,これまで研究実績のある最終腹部神経節を用いて,カルシウム感受性色素の導入方法の検討を行った。その結果,多数のニューロンによる集団的な神経活動をモニタするためには,神経節のシース下にAM体色素をマイクロインジェクションする方法が最も適切であることが分かった。年度後半では以上の結果を踏まえ,脳神経節シース下にカルシウム感受性色素Oregon Green BAPTA-1 AMを注入し,その蛍光画像を観察した。キノコ体傘部は,腹部神経節に比べて神経細胞密度が高いためか,色素の浸透が十分ではなくやや蛍光が暗かった。浸透時間や注入液に加える面活性剤の濃度を調節することで改善が期待される。さらに,正立蛍光顕微鏡下にin vivoの状態でキノコ体傘部をイメージングできるプレパレーションを作成し,触角にバニラとペパーミントの匂い刺激をそれぞれ与えたときのキノコ体のカルシウムイメージングを試みた。しかし,どちらの刺激でもカルシウム応答は誘導されなかった。次に,同じプレパレーションにおいて,触覚への匂い刺激と組み合わせて,小顎に10%...

• Analysis of Extraction Mechanism of Airflow Information in the Cricket Cercal Sensory System
  Grants-in-Aid for Scientific Research
  2004 - 2005

  The aim of this project is to elucidate the neural process of extraction and integration of directional information of air current in the cricket cercal sensory system, using calcium imaging and electrophysiological techniques. In 2004, the calcium imaging of the mechanosensory afferent neurons demonstrated that air-current stimuli from different directions induced different spatial patterns of Ca^<2+> elevation in the terminal arbors of sensory afferents within the terminal abdominal ganglion. To characterize the spatial patterns of the air-current-evoked ensemble activity of afferents, the optically-recorded responses to the repeated air-current stimuli from different directions were averaged and filtered. Based on the averaged image, we derived activity-pattern maps representing the direction of air current within the afferent projection. In 2005, we simultaneously monitored the Ca^<2+> responses to air-current stimuli at the dendrites of the identified giant interneurons (Gls) and the mechanosensory afferent terminals having synaptic connections on that dendritic branch. And, we compared the directional tuning properties of the postsynaptic GIs 10-2 and 10-3, which have different dendritic arborization pattern. The results suggest that the individual dendrite of 10-3 extracts distinct directional sensitivities from presynaptic afferents in the local region occupied by that dendritic branch. On the other hand, the dendrites of 10-2 extracts the directional information represented by ensemble activity patterns within the afferent projection. Since the electrotonic distances from the spike-initiating zone (SIZ) to each dendrite in 10-3 vary from each other, the directional sensitivity extracted by the nearest dendrite from SIZ will dominate the tuning properties of the voltage responses. In 10-2, the electrotonic distances from SIZ to each dendrite were close to each other. Therefore, the directional sensitivity extracted by all dendrites will be reflected to the overall tuning properties under the same weight. It is possible that the differences in the distribution of synaptic weights due to the dendritic geometry may be related to algorithm for the extraction and integration of the sensory information in the postsynaptic interneurons.

• 昆虫単一神経細胞における入力部位マッピングと細胞内マルチサイトレコーディング

  昆虫単一細胞内の局所的演算機能を明らかにするために、コオロギ気流応答性巨大介在ニューロン(giant interneuron : GI)の樹状突起部での細胞内電位記録と高速Caイメージングの同時記録を行い、活動電位の波形とCa応答パターンの関係を調べた。GIの上向性軸索への逆行性刺激によるbackpropagating spikeと、GIに興奮性入力を持つ1次感覚ニューロンへのシナプス刺激によるsynaptic spikeは、ともに一過性の細胞内Ca濃度上昇を引き起こすが、樹状突起末端での濃度上昇はsynaptic spikeによるものの方が大きかった。このときGIの活動電位波形は記録箇所によって異なり、特にCa濃度上昇に差が見られた樹状突起部から誘導されたsynaptic spikeはbackpropagating spikeよりも振幅・幅ともに大きかった。さらに、左右の1次感覚ニューロン群を別々にシナプス刺激したとき、記録箇所と同側のシナプス刺激は活動電位の振幅を増大させ、その部位でのCa上昇は増強された。以上の結果は、樹状突起末端部での活動電位波形が変化することによって、活性化される電位依存性Caチャネルの数量が影響を受けることを示唆している。
  さらに活動電位の伝播動態を調べるため、GI内の異なる2カ所から活動電位の誘導(マルチサイト・レコーディング)を行ったところ、d...

• 高速イメージングによる昆虫単一神経細胞内情報処理の解析

  コオロギの巨大介在ニューロン(giant intemeuron : GI)を材料として、単一神経細胞内活動を高速イメ一ジング法によって可視化し、細胞内の局所的演算機能を明らかにすること試みた。その結果、カルシウム濃度感受性蛍光色素Oregon green BAPTA-1とフォトダイオード・アレイおよびIntensified CCDカメラシステムを用いて、単発の活動電位に伴う一過性の細胞内カルシウム濃度上昇(Ca transient)を捉えるのに成功した。このCa transientは活動電位数と頻度に依存し、また、受容体チャネルからの流入や代謝型受容体を介した細胞内ストアからの放出によるものではなく、電位依存性チャネルからの流入によるものであることが確認された。一方、左右の尾葉神経束をそれぞれ刺激したところ、刺激する神経束によってGI樹状突起内のCa transientのamplitudeが異なった。これらの結果から、GI内Ca濃度変化がシナプス入力に依存するメカニズムについて、次の2つの可能性が示唆された。
  1.GIの樹状突起内を逆伝搬する活動電位によるCa transientがシナプス入力によって増幅される。
  2.GI内における活動電位発生部位/伝搬様式自身がシナプス入力によって変化する。
  そこで、GI軸索への逆行性刺激とシナプス刺激で誘導されるCa transientを...
