Validating intracranial source estimation of α oscillations, we observed “α blocking” by visual stimulation. Specifically, the contrast between S-RS versus M-RS (collapsed across groups) isolated α power reduction at M-RS across a large cluster (624 voxels) spanning bilateral visual cortices (peak voxel: −20, −100, 0; t = −4.50, d = 1.09).
