spatial mixing simulation

Published: November 24, 2020

EEG analysis in sensor space may yield distorted measures. 2 rhythms (at red & blue locations) with slightly different peak frequency mix across space. the power spectrum of the signal recorded at the green electrode now has 2 peaks in the alpha band. 🤔 pic.twitter.com/jc3HMjMWNs

topographical distribution of auditory sources in MEG vs. EEG

Published: March 14, 2024

in auditory paradigms using MEG, peak activation is over temporal sensors. with EEG, curiously often peak activation is on vertex channels. 🤔

it feels counterintuitive, given the distance from source, right? but it is expected, as this simulation with 2 active dipoles shows. pic.twitter.com/P91W2bEmg8

paper: waveform shape in bats

Published: March 07, 2024

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).
