英文摘要：

Asymptotic behavior and exponential stability of solutions of neural networks with McCulloch-Pitts nonlinearity are investigated. We discuss asymptotic behaviors and global exponential stability in the different thresholds cases. In particular, some new necessary and sufficient conditions are extablished in the critical case. This resuhs generalize the previous results given in the literature.
