Epileptogenic zone in patients with ictal derealization‐like phenomena. Lesion overlap analysis highlighted the right posterior mesial temporal lobe (MTL) [centered on Montreal Neurological Institute (MNI) x = 28, y = −21, z = −14], which was found to be involved in four out of seven patients with DR. The number of overlapping lesions is illustrated by color, from violet (n = 2) to red (maximal lesion overlap, n = 4).
