Functional magnetic resonance imaging and electrode placement. (A) Pre-surgical fMRI obtained while participant P1 pressed different buttons on a handheld device while watching videos showing desired movements. (B) Exemplary placement of SEEG electrodes (participant 3). (C) Photograph of HD ECoG electrode placement for recordings in participant P1_03. (D) Experimental setup where participants received visual cues of hand movements on a laptop computer with cues lasting 3 or 4s followed by a 3 or 4s period of rest; the clinical recording system (Natus Medical, Inc.) is not shown and was always connected for continuous data acquisition.
