Reconstruction of depth electrodes and the epileptogenic zones (EZs) that were resected. (A) Reconstruction of depth electrodes in the bilateral hemispheres of Patient 1. (B) Reconstruction of depth electrodes in the bilateral hemispheres of Patient 2. (C) Reconstruction of depth electrodes in the left hemisphere of Patient 3. (D) The EZs of Patient 1 in the left anterior temporal lobe and base of the occipital cortex. (E) The EZs of Patient 2 in the left right upper post-central and paracentral lobule. (F) The EZs of Patient 3 in the left anterior insular and posterior part of the inferior frontal gyrus.

Site of electrical stimulation in different brain areas evoking LLE. (A) Site of electrode contact in the insula evoking loss of the right hand. (B) Site of electrode contact in the parietal operculum evoking loss of the right side of the body and right upper limb. (C) Site of electrode contact in the posterior dorsal cingulate evoking loss of the right hand. (D) Site of electrode contacts evoking LLE based on a composite brain model of all patients.
