The relations between electrical synapse and the mechanism of epilepsy in genetical epilepsy prone rat

在电突触耦合的情况下，研究结果指出：在中等强度的噪声时，耦合的神经元群处理信号的能力随着耦合强度的增加而增加，达到一个最优的值，然后降低。

In the presence of electrical synapse , the ability of the neuron ensemble transmitting the aperiodic signal precisely can be enhanced at certain optimal coupling strength for the case of moderate noise . However , it is decreased with increasing coupling strength in the case of small noise intensity .

确证AP涉及知觉机制，其电突触具有部位分辨与整合功能。
