摘要：

It is known that stimulus-evoked oscillatory synchronization among neurones occurs in widely separated cortical regions. In this paper we provide a possible mechanism to explain the phenomenon. When a common, random input is presented, we find that a group of neurones-of Stein's (integrate-and-fire) model type with or without reversal potentials-are capable of quickly synchronizing their firing. Interestingly the optimal average synchronization time occurs when the common input has a high coefficient of variation of interspike intervals (greater than 0.5) for this model with or without reversal potentials. The model with reversal potentials more quickly synchronizes than that without reversal potentials.
