Dominant, left anteromedial temporal lobe resection (AMTLR) for seizure control carries risks to verbal episodic memory and visual object naming. Consistent with traditional thinking, decline is considered a consequence of hippocampal removal naming has been attributed lateral resection. Interestingly, recent findings suggest potential relation between integrity, which consistent studies that link the hippocampus higher level processing. Historically, evaluated using tasks; however, can also be assessed auditory descriptions. Recent cortical stimulation have shown neuroanatomic distinction description We speculated unlike naming, not involved in hypothesized AMTLR would result decline, despite decline.
