We included 101 participants in this study: 32 patients with right mTLE, 32 with left mTLE and 37 healthy participants. All participants gave written consent to this study which was approved by the UHN Research Ethics Board. Each patient had a diagnosis of unilateral mTLE based upon localization of seizure focus to the MTL during extended EEG and video monitoring. Presence of mesial temporal lobe sclerosis (MTS) was determined by a neuroradiologist at our epilepsy clinic (see Table 1 for demographic and clinical information).
