Abstract.In this paper, we investigate a class of impulsive Cohen-Grossberg neural networks with time varying delays and distributed delays on time scales. By applying $M$-matrix theory and the nonlinear measure approach and constructing some suitable Lyapunov functions, sufficient conditions are obtained for the existence and global exponential stability of equilibrium point for a class of impulsive Cohen-Grossberg neural networks with discrete and distributed delays on time scales.
