Sufficient conditions are derived for the delay independent stability
of the equilibria in Hopfield's graded response networks of the type d
x(i)(t)/dt = -b(i)x(i)(t) + SIGMA(j=1)n a(ij)f(j)(mu(j)x(j)(t - tau(ij
)) + F(i)(t) (i = 1,2,...,n) when the external inputs F(i) are held te
mporally uniform. A generalization to continuously distributed delays
is briefly indicated. Several illustrative examples are numerically si
mulated and the results of simulations are graphically displayed.
