We consider the neural network model (Miyashita, 1988. Griniasty et al., 19
93) proposed to describe neurophysiological experiments in which structural
ly uncorrelated patterns are converted into spatially correlated attractors
. For such a network of N neurons and for values of the coupling constant a
between succeeding patterns, taken in the interval [0, 1/2), we prove the
existence of a threshold storage capacity alpha(c)(a) such that there exist
s a local minima (in the energy function) near each of the M(N) (<alpha(c)(
a)N) stimuli patterns. (C) 1999 Elsevier Science B.V. All rights reserved.
