Both had their visas denied, so now those positions remain unfilled.

New preprint from the lab, led by post-doc @cheolsoh.bsky.social and former post-doc Mario Hervault (now Asst Prof at UGrenoble).
The boys used synchronous intracranial recordings from the human subthalamic nucleus & EEG to study β bursts during global & selective response inhibition.

Interpreting EEG requires understanding how the skull smears electrical fields as they propagate from the cortex. I made a browser-based simulator for my EEG class to visualize how dipole depth/orientation change the topomap.

Our group has been looking at beta bursts for the last 5 years, but we do it a little differently than most - we group into types them based on their waveforms. In this open access article we lay out why and what we think this might mean

Sometimes I learn a new concept online - like "AI-generated participants in Psych experiments" - and I wonder whether the purpose of the whole internet is just is finding ever more bespoke pieces of information that make me specifically as angry as humanly possible.
AI-generated ‘participants’ can lead social science experiments astray, study finds
