scanning for oscillations in intracranial EEG

Published: November 14, 2023

intracranial EEG data from the human brain features extremely rich dynamics. this is a scan through frequency space to find pronounced oscillations in different regions.

some of these rhythms are quite hard to see with non-invasive recording modalities! pic.twitter.com/n5QkJFR0kc

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).
