研究了一个具有全局缓慢衰减抑制耦合的多个异质可兴奋神经元模型。当神经元内在兴奋性参数随机分布时，系统表现出四种行为模式。除了同步的周期性和异步制度，我们得到两个非周期性制度，与爆发率神经元兴奋性的阶梯状函数。在一种状态下，系统是部分同步的，而在第二种状态下，系统是部分反同步的。这两个政权之间的过渡是不连续的无序增加。
A model of many heterogeneous excitable neurons with a global slowly decaying inhibitory coupling is studied. When neuronal intrinsic excitability parameters are randomly distributed, the system exhibits four regimes of behavior. In addition to synchronized periodic and asynchronous regimes, we obtain two aperiodic regimes, with bursting rate a staircaselike function of neuron excitability. In one regime, the system is partially synchronized and, in the second, partially antisynchronized. The transition between these two regimes is discontinuous as the disorder increases.
