detrended fluctuation analysis on neural oscillations

Published: July 08, 2019

Are neuronal oscillations different than just filtered 1/f-noise? Yes, for instance in their signal characteristics: they display intricate long-range temporal correlations in their band amplitudes; measured by a detrended fluctuation exponent (DFA) close to 1. pic.twitter.com/pohWRDWf2V

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).
