Outline of Final Research Achievements |
To understand the mechanism of active information foraging by animals, we constructed a mathematical model of the detection of objects with active whisking. In this model, we assume that objects randomly appear and disappear in a one-dimensional space and that a whisker scans the space to obtain information on the position of the objects. We derived the whisking algorithm that maximizes the information gain. However, because the whisking pattern generated by the model was inconsistent with the rats' whisking, we failed to compare the model with physiological experiments. Additionally, we conducted a study on a system of coupled phase oscillators driven by noise.

Academic Significance and Societal Importance of the Research Achievements |
モデル主導で効率的な生理学実験を構成する手法を模索した.非常に単純な感覚運動系であるラットのヒゲを題材にして理論的な考察を行い,生物学的拘束条件の考察の重要性に光を当てた.これに加えて,ノイズ下で相互作用する位相振動子のダイナミクスで低次元記述が可能である場合を発見した.これは多体相互作用の系としては最も研究が進んでいる蔵本モデルの一つの拡張であり,同期現象の数理の理解に寄与するものである.
