Yamaguchi’s: Modeling of biological oscillation systems(1980-2001)

Simple biological system is all the time supervisor to Yamaguchi. Simple oscillation and simple wave propagation endow fascinating complexity and finally intelligence to biological systems.

It was collaborated with colleagues and students at Universiy of Tokyo, Tokyo Denki University and Tokyo Medican and Dental University.
