We wondered if the task (video) engagement modulates the cortical EEG's relationship with anatomy. Turns out yes; we found differences during video and rest, with part of the sensorimotor cortex exhibiting strengthened coupling to anatomy.

We found that the wideband EEG in the sensorimotor cortex is strongly constrained by the anatomy, with higher-order systems exhibiting flexibility, a trend consistent across multiple videos and resting-state.

The end of 3 yrs of "ah this looks reassuring, but,"

We investigated the link b/w source-localized continuous EEG (Movie &Rest) and individual anatomical scaffold using Eigenmodes / Graph Signal Processing(GSP) #neuroskyence
