Sebastian Hellmann @sehellmann.bsky.social · 25/08/2026Pre-stimulus Beta activity mediated the effect of previous choices on drift rate only in a stable environment. In the volatile environment, previous choice was not credibly mediated by prior activation. Here, we see a cross-over of effects from cue, through Beta power, to drift rate. 010 1
