Spatiotemporal chaos collapses to either a rest state or a propagating pulse in a ring network of diffusively coupled, excitable Morris-Lecar neurons. Adding global varying synaptic coupling to the ring network reveals complex transient behavior. Spatiotemporal chaos collapses into a transient pulse that reinitiates spatiotemporal chaos to allow sequential pattern switching until a collapse to the rest state. A domain of irregular neuron activity coexists with a domain of inactive neurons forming a transient chimeralike state. Transient spatial localization of the chimeralike state is observed for stronger synapses.
在扩散耦合的兴奋 Morris-Lecar 神经元环形网络中，时空混沌要么崩溃到静止状态，要么崩溃到传播脉冲。向环形网络添加全局变化的突触耦合会揭示复杂的瞬态行为。时空混沌崩溃为一个瞬态脉冲，该脉冲重新引发时空混沌，从而允许顺序模式切换，直到崩溃到静止状态。不规则神经元活动的域与不活跃神经元的域共存，形成瞬态类混沌状态。对于较强的突触，观察到类混沌状态的瞬态空间定位。
