Collection description

In this research, we have examined the stochastic Wilson-Cowan neural network model to pinpoint the conditions that influence network behavior, focusing on criticality and bistability. Recent magnetoencephalography findings underscore the functional importance of bistable criticality in the dynamics of the brain in a healthy, awake, resting state, suggesting its potential role as a pathophysiological factor in epilepsy. By applying the Wilson-Cowan model, we sought to uncover the roots of bistability, attributed to neurons' superlinear activation function. Beyond its clinical implications for conditions like epilepsy, bistability, and multistability serve as crucial characteristics of networks with associative memory capabilities. Consequently, we explored a variant of the Wilson-Cowan model designed to facilitate associative memory, akin to the approach of the Hopfield model.
