On the formation of persistent states in neuronal network models of feature selectivity

J Integr Neurosci. 2003 Jun;2(1):103-23. doi: 10.1142/s0219635203000202.

Abstract

We study the existence and stability of localized activity states in neuronal network models of feature selectivity with either a ring or spherical topology. We find that the neural field has mono-stable, bi-stable, and tri-stable regimes depending on the parameters of the weighting function. In the case of homogeneous inputs, these localized activity states are marginally stable with respect to rotations. The response of a stable equilibrium to an inhomogeneous input is also determined.
