Fig. 1. Sagittal MRI within the Talairach atlas (45) demonstrating the long axis of the hippocampus (A). The alveus demarcates the superior boarder of the hippocampus rostrally with the amygdala above (B). The posterior limit of the hippocampal head is defined as the first oblique coronal slice in which both cerebral peduncles are present (C). The posterior limit of the hippocampal body is defined as the first oblique coronal slice in which all four colliculi are present (D). Outlines shown in gray dots.
