paper: waveform shape of neural oscillations & spatial mixing

May 16, 2019

Our newly published study: https://t.co/LbQTNKmKXb We quantify waveform shape in a large EEG dataset and explore what happens when you mix non-sinusoidal signals with different delays. E.g.: Alpha and beta amplitudes will not necessarily be correlated!

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
