起搏器影响下的耦合神经元之间的同步

SYNCHRONIZATION OF COUPLED NEURONS UNDER THE CONTROL OF PACEMAKER

讨论了起搏器对双向电耦合的Hindmarsh-Rose神经元之间同步行为的影响.结果表明,在适当的参数组合下,起搏器能够增强也能抑制两个全同神经元之间的完全同步,增强三个全同的神经元之间的完全同步;处于不同放电模式的三个非全同神经元,起搏器在足够大的控制强度下能够诱发相位同步、近似同步,当进一步考虑时滞后,起搏器神经元更容易诱发它们之间的这种同步行为.

The effects of pacemaker on synchronization in bidirectional coupling Hindmarsh - Rose neurons with gap junction were studied. Results show that, with proper parameters, pacemaker can enhance or inhibit the complete synchronization of two identical neurons, while it can always enhance the complete synchronization of three identical neurons. For three un - identical neurons with different firing patterns, pacemaker can induce phase synchronization and nearly complete synchronization if the controlling strength is big enough. When time delay was considered, the pacemaker was more likely to trigger such synchronization.
