| 摘 要： | 实验研究发现大脑皮层电活动和信号传播有类似螺旋波的特征.本文利用包含离子通道效应的Hodgkin-Huxley神经元构造规则网络来研究螺旋波的形成机理,利用缺陷阻挡行波的方法在神经元网络中诱导到不同周期的螺旋波,分析了螺旋波产生条件和耦合强度对螺旋波的影响.同时,对脑皮层中螺旋波形成的机理进行了讨论.

| Abstract: | The experimental results confirmin that spiral wave can be observed in the cortex of brain and the electric signals in neurons can proprgate with spiral wave. The mechanism for the formation of spiral wave is investiaged in the regular network of Hodgkin-Huxley, which can measure the effect of ion channels, and the sprial waves with different periods are developed to occupy the network by blocking the travelling wave with defects. The basic condition for inducing spiral wave and the effect of the couling intensity are analyzed. The potential mechanism for developing spiral wave is discussed. |
