Lecture on Theories of Life

Associate Prof. Masatoshi Murase

Graduate School of Science

Course Structure:

1.5 hours / session

Maatoshi Murase “The Dynamics of Cellular Motility” Wiley (1992), p30, 31, 302 ( left) and p121 (right).

Course Description

The processes that underlie cellular motility - the contraction of muscle and the beating of cilia and flagella - not only share a common mechanism, based on sliding filaments, but can also share oscillatory dynamics.
The present lecture uses nonlinear dynamics as a framework to approach complex behaviours in motile systems and presents mechano-chemical oscillatory systems as a prototype of nonlinear science. The key idea from nonlinear dynamics is that very simple nonlinear models can have complicated behaviours and that although biological systems do have intricate and complicated structures and behaviours, simple nonlinear models can quantitatively describe these behaviours and a mathematical analysis of such simple models can help in the understanding of biological processes.
