我们用数值方法刻画了神经元Fitzhugh-Nagumo耦合模型的预期同步机制。我们考虑两个单向耦合的神经元(在主从结构中)，受到相同的随机外力，并在从神经元中具有经常性的抑制性延迟连接。我们证明了该方案导致了预期的同步，在这种情况下，从神经元发射与主神经元相同的脉冲串，但时间更早。我们在参数空间(耦合强度、预期时间)上刻画了同步，并引入了几个度量同步程度的量。(C)2003 Elsevier Science B.V.保留所有权利。
We characterize numerically the regime of anticipated synchronization in the coupled FitzHugh-Nagumo model for neurons. We consider two neurons, coupled unidirectionally (in a master-slave configuration), subject to the same random external forcing and with a recurrent inhibitory delayed connection in the slave neuron. We show that the scheme leads to anticipated synchronization, a regime in which the slave neuron fires the same train of pulses as the master neuron, but earlier in time. We characterize the synchronization in the parameter space (coupling strength, anticipation time) and introduce several quantities to measure the degree of synchronization.
