detrended fluctuation analysis on neural oscillations

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

beta as bursts / beta as a rhythm

June 06, 2024

"beta-activity as bursts", I am def 💯 OK with that.

but imho the pendulum has swung too far in the direction that all beta activity equals close to 1-2 cycle bursts. so just to illustrate diversity, here is some more sustained beta-activity, resting-state EEG.

impact of crosstalk in MEG/EEG

May 16, 2024

MEG/EEG: "we use source reconstruction" – all problems solved?

plotted here: crosstalk – possible contribution from other locations to reconstructed activity @ red dot. no strong activity at these locations: 👍 otherwise: 🫠
➡️crosstalk can be from distant locations pic.twitter.com/FetHqq5LoZ
