Neurophysiological results. A vERP elicited by stimulus grating onset (P1) and motion onset (N2m) onset relative to respective pre-stimulus baseline. B Time–frequency (ERP) response to stimulus onset (theta, 4–7 Hz) and motion onset (delta, 1–4 Hz). C Head map of stimulus-onset theta activity by group. D Head map of motion-onset delta activity by group
