Outline of Final Research Achievements

We investigated information propagation mechanism in large size population that consists of small size populations in which the elemental members communicates with each other. Techniques for observing the evolutionary dynamics in the large size population were presented. A novel concept of evolutionary dynamics that can be defined in several different fitness landscapes was proposed. Neurophysiological experimental data (calcium imaging data) of in vitro and in vivo mice's respiration were obtained. We now pursue these investigations to develop mathematical models that explain the evolutionary dynamics and the neuroglial network.
