Topic: microscopic neuron network model

Brain rhythms in the alpha frequency range [8Hz-12Hz] are present in idling conditions and sleep. For instance, a prominent occipital alpha wave emerges in mammals when the subjects closes eyes (alpha generation) and it is blocked when opening eyes (alpha blocking). This switch in alpha power is accompanied by an inverse switch in gamma activity [1]. Considering input as random input fluctuations, this switch may result from an alteration in exogenous fluctuations. In a first part, the work proposes a mathematical mesoscopic neural mass model for the cortico-thalamic feedback (CTF) loop derive
