Schematic diagram of the depth and subdural electrode placement. This view from the inferior aspect of the brain shows the approximate location of depth electrodes, oriented along the anterior–posterior plane in the hippocampi (RTD—right temporal depth, LTD—left temporal depth), and subdural electrodes located beneath the orbitofrontal and subtemporal cortical surfaces (ROF—right orbitofrontal, LOF—left orbitofrontal, RST—right subtemporal, LST—left subtemporal).
