bandpass-filtering a waveform

Published: December 03, 2019

Why does phase-amplitude coupling arise for non-sinusoidal signals? Amplitude of the band-pass filtered harmonic will be impacted in a systematic way by the base oscillation. Here: increased beta at the trough and decreased beta at the peak of the base alpha-oscillation. pic.twitter.com/f1ZFaeiRcb

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).
