In rats, postnatal 3 to 5 weeks are critical for their development (namely, critical period), during which the excitatory and inhibitory synapses mature to form functional circuits in visual cortex.

By using the theory of topological degree and Liapunov functional methods,this paper discusses the existence and global asymptotic stability of the equilibrium for Hopfield neural networks with dynamic synapses and time delay.
