Fast Contralateral Propagation of After-Discharges Induced by Stimulation of Medial Temporal Lobe

Abstract

In a patient with unilateral hippocampal sclerosis, stimulation of the contralateral anterior perirhinal cortex triggered after-discharges in the sclerotic hippocampus, followed in one case by a seizure. The spatial and temporal characteristics of these responses reveal fast interconnections between the two medial temporal lobes.
