近赤外レーザーを用いた次世代人工内耳の開発と評価
小林 耕太; 古山 貴文; 飛龍 志津子; 宮坂 知宏; 玉井 湧太
本申請研究は近赤外光刺激を利用して次世代人工内耳を開発することを目的としている。感音性難聴者の治療に主としてもちいられる人工内耳は、蝸牛内に外科的に挿入した電極アレイにより電気的に聴神経(螺旋神経節細胞)を刺激することで聴力の回復をおこなう。この従来型人工内耳は聴覚末梢器官への外科手術を必要とするため、副作用などのコストが問題となっている。本計画では非接触で神経活動を引き起こさせる手法である、赤外光により熱的に細胞を刺激する手法を人工内耳に応用し、神経活動を非接触で誘発し、聴力を再建(または補助)する手法の開発を目指す。具体的には、動物実験により光刺激が再建可能な知覚内容を検討するとともに、装置を長期装用した場合の生体への影響(安全性)を評価する。また、主にヒトを対象として装着方法および言語知覚を再建するための刺激アルゴリズムを検討した。当該年度の研究により、動物実験では光刺激により、近赤外光の刺激部位および刺激強度を変えることで周波数と音圧の知覚を制御可能である可能性が示された。また実験(刺激)期間中に動物の行動応答の低下は見られなかったことから赤外光刺激が一過性な神経応答の低下をもたらすことは無いことが分かった。さらに、ヒトを対象にした実験では光刺激の産み出すと想定される音声の知覚は学習により優位に向上すること、学習の刺激としては視聴覚複合刺激が能力向上の効果が高いこと、また学習後には従来型の人工内耳と同程度の知覚を生み出し得ることが分かった。, 日本学術振興会, 科学研究費助成事業 基盤研究(B), 2021/04 -2025/03, 基盤研究(B), 同志社大学

音響GPSロガーを用いた,人為的景観環境下の野生コウモリの移動生態に関する研究
飛龍 志津子; HEIM OLGA
In September 2019, I joined a short field trip to the Fukui prefecture in order to capture and tag Japanese horseshoe bats and to collect fecal samples. After this trip, I viewed the available GPS-data from bats that were tracked from the year 2015 to 2018. This data set allowed an extensive analysis using generalized linear mixed effect models. This statistical analysis is almost finished and will be summarized and discussed in the manuscript draft that I have composed.
In parallel, I have extracted the DNA from the available fecal samples originating from various bat species (including the Japanese horseshoe bats). Also, specific DNA regions (from all samples) that are used to identify prey insects were amplified using a set of 3 different primers. Due to the coronavirus outbreak and the resulting limits on resource access (e.g. indexing primers, laboratory) the diet analysis is currently on hold until the situation becomes less serious.
Another major achievement was the resubmission of a manuscript on the topic of flight and echolocation call behavior of Japanese horseshoe bats. Due to my skills, especially in statistical analysis, I was able to join and contribute to the manuscript., 日本学術振興会, 科学研究費助成事業 特別研究員奨励費, 2019/10 -2022/03, 特別研究員奨励費, 同志社大学
Describing the undescribed bone X
KOYABU DAISUKE
In this study, we conducted a multifaceted research on a bone that has not been described in conventional anatomical systems: the auriculohyoid bone. We found that there are two patterns of the auriculohyoid in the lineage X (will be clarified after publication of the paper): lineage Xa, which has completely ossified bones, and lineage Xb, in which the trait remains cartilaginous in adults. Embryological observations on fetal samples ruled out the working hypothesis. We initially hypothesized that the lateral end of the Reichelt's cartilage, which is the protoligament of the hyoid bone, would separate and ossify to differentiate into the otolingual bone, but we found that the ossification of the ventral base of the auricular cartilage was the result of ossification. Gene expression analysis revealed that BMP, FGF, and Sox9 are largely involved in the dynamics., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2018/10 -2022/03, Fund for the Promotion of Joint International Research (Fostering Joint International Research (B))
Study on 3-D swarm intelligence sensing and its engineering application learned from collective flight of bats
Hiryu Shizuko
This study aims to elucidate the mechanism of jamming avoidance behavior in acoustic sensing by bats during group flight, and to direct toward knowlegds for engineering applications. Echolocating bats are classified into two types, FM bats and CF-FM bats, based on the difference of ultrasounds. We found that FM bats avoid acoustic interference by changing frequencies, and then also implemented this behavior mechanism in autonomous vehicles and evaluated it through obstacle avoidance driving under interference. As a result, we could confirm that the bat tactic is useful from an engineering standpoint. On the other hand, we also found that the Doppler shift compensation behavior of CF-FM bats reduces the interference of signals from other individuals., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2018/04 -2022/03, Grant-in-Aid for Scientific Research (A), Doshisha University
The ossicle X
Koyabu Daisuke
While there is consensus that powered flight evolved only once in the lineage, whether laryngeal echolocation has a single origin in bats or evolved multiple times independently remains disputed. Our comparative embryological investigations found that there is no developmental difference in the hearing apparatus between non-laryngeal echolocating bats (pteropodids) and terrestrial non-bat mammals. In contrast, the echolocation system is developed heterotopically and heterochronically in the two phylogenetically distant laryngeal echolocating bats (rhinolophoids and yangochiropterans), providing the first embryological evidence that the echolocation system evolved independently in these bats., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2018/06 -2021/03, Grant-in-Aid for Challenging Research (Exploratory)
Non-invasive hearing prosthesis using infrared laser
Kobaysi Kohta
This study focused on novel method for stimulating nerves with an infrared laser as a substitute for the highly invasive cochlear implants. We demonstrated that t sound perception is generated by stimulating auditory nerves without contacting tissues. In addition, for developing a non-invasive cochlear implant in the future, we conducted basic research on neurophysiological basis of it. The results show the feasibility of an infrared laser cochlear implant that does not require surgery, will lead to the solution of the deafness problem, which will become more serious due to the aging of society., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), 2017/04 -2021/03, Grant-in-Aid for Scientific Research (B), Doshisha University
Systems Science of Bio-Navigation
Hashimoto Koichi
In the "Systems Science of Bio-navigation", we aimed to establish a new academic field to measure, analyze, model and verify human and animal movement behavior. As a result of active interdisciplinary research, we have developed a series of state-of-the-art small multidimensional sensor devices called "Logbot" (logging robot). We have also developed a set of softwares for data-driven analysis of the measured multidimensional movement data. By using these methods, we have succeeded in elucidating novel behavior of wild animals and in mathematical modeling of navigation of various animal species., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2016/06 -2021/03, Grant-in-Aid for Scientific Research on Innovative Areas (Research in a proposed research area), Tohoku University
Navigation behavior by active sensing in bats
Hiryu Shizuko
In this study, we conducted advanced measurements of the navigation behavior of bats using various scales and measurement methods, with the aim of clarifying the unique navigation tactics of bats involving ultrasonic sensing. The main results are as follows: 1) We discovered that bats flying in groups change the frequency of their ultrasound pulses. In addition, we demonstrated that jamming avoidance behavior of bats during group navigation is useful from an engineering point of view. 2) Successful bio-logging using a custom-made acoustic GPS logger has provided valuable new insights into the movement ecology of echolocating bats in the wild. (3) Repeated flights in obstacle space showed a learning effect that reduced the cost of flight paths and ultrasonic sensing, indicating that navigation changes with the internal state of the individual., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2016/06 -2021/03, Grant-in-Aid for Scientific Research on Innovative Areas (Research in a proposed research area), Doshisha University

Investigation of real-time spatial search algorisms by active sensing of bats using ultrasound
HIRYU Shizuko
The purpose of this study is to investigate the sophisticated behavioral sensing strategies of echolocating bats through the laboratory and field measurements using bats. We found that 1) the bats (Rhinolophus ferrumequinum nippon) actively expand their beam width depending on the situation, especially at the final stage of capturing target prey, 2) the bat species with narrow beam width more frequently shift their acoustic gaze during flight to compensate their narrower view sight, 3) the bats direct their pulse emission toward important object during obstacle avoidance flight. Furthermore, the wild bats pay their attention (pulse direction) toward not only immediate prey but also the next prey, which was also suggested by the mathematical modeling describing the flight attention., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Young Scientists (A), 2012/04 -2015/03, Grant-in-Aid for Young Scientists (A), Doshisha University

Navigation strategy of acoustical sensing by bats.
HIRYU Shizuko
We investigated how CF-FM bats adjust pulse direction and beam width according to prey position using 31-ch microphone array system. When the bat started terminal phase at approximately 1 m from the moth, G. pryeri sometime showed distinctive evasive flight. At the same time, the bats broadened the beam width of some emissions in both horizontal and vertical planes. When the moth starts evasive flight, tracking accuracy of echolocation by the bat would decrease compared to that during the approach phase. However, in 97% of emissions during the terminal phase, the beam width of the pulse was wider than the misalignment(target direction-pulse direction) as well as during search and approach phase. These findings indicate the bats actively adjusted their beam width to retain moving target in spatial window of echolocation at final stage of capturing., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Young Scientists (B), 2009 -2011, Grant-in-Aid for Young Scientists (B), Doshisha University

The biosonar system employed by bats was examined based on acoustical, physiological and dynamic measurements for understanding their effective bio-navigation algorism. As a result, (1) collaboration control in flight and acoustical sensing behaviors by bats, (2) look-ahead control of pulse direction during flight, and time-sharing processing for multiple target, (3) avoidance for self-jamming (pulse-echo ambiguity) by shifting frequency range, (4) consistence of electrophysiological measures of best frequency and latency distributions in inferior colliculus of Pipistrellus abramus with behavioral measures during foraging in this species., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research on Innovative Areas (Research a proposed research project), 2008 -2010, Grant-in-Aid for Scientific Research on Innovative Areas (Research a proposed research project), Doshisha University

音響行動観測に基づいた生物ソナーシステムの解明とその工学的応用
飛龍 志津子
本研究では、水・陸の異なる環境下で実施されるイルカとコウモリのエコーロケーション行動の比較から、それぞれの生物圏へ最適化された音響計測システムの解明並びにその工学的応用を目的としている。本年度は、イルカの長期音響モニタリング実施に向け、情報収集や実験環境の確保、また試験的にイルカのエコーロケーション行動時の音響データの習得を目指した。
1.イルカの長期音響モニタリング実施に向け、水族館(伊豆三津シーパラダイス)にて実験内容や計画の実現性について打ち合わせを行った。12月には、同水族館において飼育下にあるバンドウイルカのエコーロケーション音声の計測を実施し、イルカとコウモリのソナー音声について基本的な音響信号情報の比較等を行った。
2.野生のコウモリが行う採餌中のエコーロケーション行動を調べるため、マイクロホンアレイ装置による3次元飛行軌跡の計測技術を確立した。また飛行経路とパルスの放射方向との関係を調べるため、実験室内に19chのマイクロホンアレイ装置を構築し、観測室内を飛行するコウモリの水平及び垂直方向のパルス放射パターンの計測を実施した。コウモリが選択する飛行経路と、それをナビゲートするエコーロケーション行動について検討した結果、コウモリが超音波パルスを変化する飛行方向に対し、一定時間先行させて放射していることを明らかにした。, 日本学術振興会, 科学研究費助成事業 特別研究員奨励費, 2007 -2007, 特別研究員奨励費, 東京大学
