主題：Dragon-king-like extreme events in coupled bursting neuron
內(nèi)容簡(jiǎn)介：We evidence occasional large amplitude events in an otherwise quiet chaotic oscillation when two Hindmarsh-Rose (HR) bursting neurons mutually interact via a combination of chemical synaptic and repulsive diffusive coupling. We characterize them as extreme events by a threshold measure. A dragon-king-like probability distribution of the extreme events is seen where small to medium size events obey a power law and the larger events that cross an extreme limit are outliers. We tried to understand the origin of extreme events in the coupled systems. The extreme events originate due to instability in anti-phase synchronization (APS) of the coupled systems via two different routes, quasiperiodicity and intermittency routes for purely excitatory and inhibitory synaptic coupling, respectively. For purely repulsive diffusive coupling, the quasiperiodic route is only seen. A simple electronic experiment using two repulsively coupled analog circuits of the HR neuron model confirms occurrence of the dragon-king-like extreme events.
