       Cohen-Grossberg neural network with distributed delays

Abstract: 
 We study the existence and exponential attractivity of
 periodic  solutions to  Cohen-Grossberg neural network with
 distributed delays.  Our results are obtained by applying the
 continuation theorem of coincidence  degree theory and a general
 Halanay inequality.
