heating up a neuron

when analyzing LFP & spikes, only few units exhibit spike-field coupling. but there are lots of rhythms in the brain, how do they arise? this toy model here shows that only a small fraction of oscillatory units need to be active in synchrony to result in a discernible rhythm. pic.twitter.com/edrkUNiG1h

spike-field coupling: when spikes occur at a preferred phase of an ongoing oscillation. in below example, a homogeneous Poisson spike train (spiking is distributed uniformly across time) is morphed into an inhomogeneous one, with more frequent spikes at the trough of the LFP. pic.twitter.com/xJWGMRheXz
