CONNECTION ENSEMBLE MODEL OF LOCAL NEURAL CIRCUITS

A connection ensemble model (CEM) of local neural circuits in central nervous system (CNS) is proposed in this work. Neuronal interactions a re investigated at two levels, i. e. the synaptic connection between s ingle neurons and the macro-connections between different neuronal gro ups. The efficacy of macro-connection is quantitatively determined by the efficacies of constituent synapses, and is asymptotically stable. This model provides a reasonable description for the functional invari ance of local neural circuits with structural diversities, which is a widely observed fact in neurobiology. It is expected that the works in CEM model would enrich the current research in neural dynamics.
