Abstract: 
 In this paper, we consider a class of shunting inhibitory cellular
 neural networks with continuously distributed delays (SICNNs).
 The delays are unbounded and the activation function is not assumed
 to be bounded.
 Using the continuation theorems of coincidence degree theory,
 Lyapunov functional method, we obtain new sufficient conditions for
 the existence and local exponential stability of periodic solutions
 of (SICNNs). Numerical examples illustrated our results are given.
