Wilson-Cowan Model

The Wilson-Cowan model describes the evolution of excitatory and inhibitory activity in a synaptically coupled neuronal network. As opposed to being a detailed biophysical model, the system is a coarse-grained description of the overall activity of a large-scale neuronal network, employing just two differential equations. Key parameters in the model are the strength of connectivity between each...

At present, as we enter the nanD and giga·scaled integrated-circuit era, there are many systna design challenges which must be overcome to resolve problems ill current systems. The incredibly increased Ilollrecllrring engineering (NRE) cost, abruptly shortelled Time­ to-Market (ITA) period and ever widening design productive gaps are good examples illllstrating the problems ill clfrrelil system...

Wilson–Cowan Equations for Neocortical Dynamics

In 1972-1973 Wilson and Cowan introduced a mathematical model of the population dynamics of synaptically coupled excitatory and inhibitory neurons in the neocortex. The model dealt only with the mean numbers of activated and quiescent excitatory and inhibitory neurons, and said nothing about fluctuations and correlations of such activity. However, in 1997 Ohira and Cowan, and then in 2007-2009 ...
