Abstract

There is persistent impairment of recent memory whenever bilateral temporal lobe resection is carried far enough posteriorly to damage portions of the anterior hippicampus and hippocampal gyrus. Severity of the loss increases with the extent of hippocampal removal. Bilateral removal of the uncus and amygdala causes no memory loss. The anterior hippocampus and hippocampal gyrus are interpreted to be critically concerned in the retention of current experience.
