Statistical-mechanical measure of stochastic spiking coherence in a population of inhibitory subthreshold neurons.

abstract：:Many animals produce pulse-like signals during acoustic communication. These signals exhibit structure on two time scales: they consist of trains of pulses that are often broadcast in packets-so called chirps. Temporal parameters of the pulse and of the chirp are decisive for female preference. Despite these signals b...
