Self-motion estimation activity. Electroencephalography (EEG) scalp topoplots (Left) of alpha-band activity for time windows before, during and after motion for the self-motion contrast. This contrast was created by using body-fixed data, averaged over all target locations, and subtracting small motion from large motion. Rightward motion was flipped across the midline and averaged with the leftward motion. This isolates activity that increases with larger motion, while subtracting out effects of target coding and constant activity. (Right) Time-frequency plot for a parieto-occipital ROI (Pz, PO3/4, POz, and PPO1/2h). Motion occurs between t = 1 and 2 s.
