摘要
电突触前膜在高于阈值的刺激下,产生一个大小不变的动作电位,突触后细胞可直接被突触前轴突中伴随动作电位产生的电紧张所激活,突触膜相当于整流器,电流只能从突触前神经元流向突触后神经元。电流流过神经元之间结合部时,连结电导将随时间变化。
The forward transfer conductance of neuronal electrotonic synapse is described. The presynaptic membrane fires an action potential via superthreshold stimulation, and the postsynaptie membrane can directly be excited by electrotonus with the action potential. The synaptic membrane is a rectificr, and the coupling conductances will change with time.
