Transition from local to global phase synchrony in small world neural network and its possible implications for epilepsy.

摘要: Temporal correlations in the brain are thought to have very dichotomous roles. On one hand they ubiquitously present healthy and underlie feature binding during information processing. other hand, large-scale synchronization is an underlying mechanism of epileptic seizures. In this paper we show a potential for transition pathological coherence seizure generation.
