rhythm peak frequency in animal LFP

April 29, 2020

peak frequencies of rhythms vary across people, but how consistent are rhythms over species? currently looking at some LFP from mouse visual cortex: the most prominent rhythm there goes away with visual stimulation but has a broad frequency peak at 4.5 Hz. 🤔 nice sharp troughs! pic.twitter.com/1wMivrISwB

waveform shape of oscillations can reflect properties of underlying spiking dynamics. if neuronal units fire in synchrony, the local field potential can be more asymmetric (here: sharp troughs).

how many spikes does it take to produce a rhythm?

April 16, 2021

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
