After having been exposed to strong visual motion in one direction, a subsequently
presented stationary visual scene seems to move in the opposite direction. This motion
aftereffect (MAE) is usually ascribed to short-term functional changes in cortical areas
involved in visual motion analysis akin to adaptation. Using magnetoencephalography
(MEG), we show increased global field activity due to the MAE which could mostly be
explained by a dipole located near the putative location of human area MT+. We further …
