Dynamic Feature Linking in Stochastic Networks with Short Range Interactions

It is well established that cortical neurons displa.y synchronous firing for some stimuli and not for others. The resulting synchronous subpopulation of neurons is thought to form the basis of object p ercep­ tion. In this paper this 'dynamic linking' phenomenon is demonstrated in networks of binary neurons with stochastic dynamics. Feed-forward con­ nections implement feature detectors and lateral connections implement memory traces or cell assemblies.
