Introduction: In the hippocampus, visual presentation of words elicits a positive deflection (P600), followed by a long lasting late negative component (LNC). These ERP components are enhanced by word repetition, presumably reflecting hippocampal memory processes. Previous studies on patients with unilateral Ammon's horn sclerosis (AHS) have indicated that the LNC response to repetitions of words, as well as the P300 in oddball paradigms, are strongly reduced in the sclerotic hippocampus (Grunwald et al., 1995). The present study extends previous findings. Methods: The study sample consisted of 19 patients with…
