Synchronization and temporal order characterized by the rate of firing are studied in a spatially extended map neuron network with coupling time delay. It is shown that there exist an intermediate noise level, where synchronization and temporal order are maximum irrespectively of the coupling time delay. Furthermore, it is found that temporal order is weakened when the coupling time delay appears. However, the coupling time delay has two-fold effects on synchronization, one associated with its increasing, the other with its decreasing. This clearly manifests that random perturbations and time delay play a complementary role in synchronization and temporal order.
