| Outline of Final Research Achievements |
In this study, I addressed the acquisition of situational dependent behavior selection indicators of an insect, using the female localization behavior of a silkmoth as the target. I developed a novel behavior measurement device, an omnidirectional moving treadmill for the insect, and carried out experiments in which I intervened in the sensory stimuli given to the moth and its output behavior. I found that when setting a delay time to the movement, the behavior was compensated by sensory feedback, and when setting a delay time to sensory input, active searching behavior occurred in order to compensate for the discrepancy in sensory input.

本研究の成果によって，人工システムが不得意とするむだ時間に対して，小規模な神経系で構成される昆虫がどのように対処しているのかを全方位移動型トレッドミルと呼ぶ新奇な実験系を通して知ることに成功した．介入系を用いてさらに実験・解析を進めることで，小規模な神経系でありながら適応的な振る舞いを支える内部コントローラを解き明かすことが可能となる．
