A Computational Model Of A Microzone Of The Cerebellum

Sule Yildirim, Associate Professor of Computer Science, Hogskolen i Hedmark, Norway

The model of a microzone of the cerebellum and its dynamical analysis in this poster is a part of the distributed modular processing research program aimed at exploring the dynamics of the mind (Houk, 2005) and (Houk, 2006). The microzone model is an essential part of a module in the cerebellum comprised of circuitry for regulating the direction and duration of an arm movement. The goal is to simulate a realistic model of how pauses and bursts in Purkinje cell discharge regulate cerebellar nuclear and motor cortical cells to control voluntary limb movements. The dynamical analysis consists of investigating the stability and movement of fixed points on a phase portrait by examining phase trajectories and bifurcations regulated by pauses and bursts of Purkinje cell discharge. This agent-based model explores both individual and aggregate behavior of microscopic modules.
