Hilbert transform for broadband signals

Published: October 11, 2020

example: a simple compound signal (red) made out of two frequency components. if you extract instantaneous amplitude and phase from the analytic signal of the compound, its phase and amplitude correspond to the circular mean of the analytic signal from individual components. pic.twitter.com/945XCXGthj

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).
