摘要
采用描述抑制连接的WLC模型分析外界刺激对七鳃鳗左右运动神经元的影响,并利用WLC模型模拟七鳃鳗神经系统的动作电位,结果表明,在直流刺激和交流刺激2种方式下,左右运动神经元的电位发放出现相互交替的变化.在交流刺激情况下,当刺激频率改变时,运动神经元的ISI序列出现加周期现象.这些数值结果解释了外界刺激情况下七鳃鳗的实验现象.
The WLC model is used to simulate the action potential of Lamprey neural system. The result shows that left or right motoneuron appears alternately fire in circumstances of direct-current and ahematecurrent stimulation. In circumstances of alternate-current stimulation, when we vary the stimulation frequency, the ISI sequence of motoneuron appears increasing periodic phenomena. These numerical results explain the experiment phenomena when lamprey is influenced by external stimulation.
