Sufficient conditions are obtained for the existence and global attractivity of periodic solutions of a class of higher-order Cohen-Grossberg type neural networks with delays. The proof is based on Gaines and Mawhin's continuation theorem of coincidence degree theory, the Lyapunov functional and a nonsingular M-matrix. One example is exploited to illustrate the effectiveness of the proposed criteria. © 2007 Elsevier Ltd. All rights reserved.
