Abstract
We investigate a mechanism of the generation of chaotic wandering observed in a four-neurons coupled chaotic neural network with coupling coefficients determined by two orthogonal stored patterns. Through the analysis of a th ree dimensional noninvertible map describing the essential dynamics of the network, we found that the chaotic wandering phenomenon occurs due to both a global bifurcation of periodic points and a collapse of chaos.
