This was an excellent experience.
I am glad that I could represent #EEGLAB, one of the largest academic #OpenScience research platforms and communities.

This also sparked an effort for sustainable funding of open science projects via a tiny overhead of research grants. Read more at osc.earth

𝗦𝗼𝗹𝘂𝘁𝗶𝗼𝗻𝘀:⁣
• Spatial filters (Laplacian) - real-time friendly⁣
• ICA source separation - more accurate⁣
⁣
The assumption "electrode X = brain region Y" is wrong. Use source-level analysis.⁣

𝗞𝗲𝘆 𝗳𝗶𝗻𝗱𝗶𝗻𝗴: A 3x3cm brain patch projected strongest to DISTANT scalp areas, not overhead. Standard deviation & entropy showed inverse patterns with distance.⁣

𝗧𝗵𝗲 𝗽𝗿𝗼𝗯𝗹𝗲𝗺: Channel-level analysis misattributes brain signals due to volume conduction mixing.⁣

⁣
New research with 1,024 brain electrodes proves EEG channels DON'T reflect local brain activity underneath the electrode.⁣
