Abstract

The hippocampus is a critical organ for memory storage and processing. The blood supply of the hippocampus is derived from the branches of the anterior choroidal artery and posterior cerebral arteries. Parts of the hippocampus are identified as a head, body, and tail; hippocampal arteries are named as anterior short, anterior long, posterior short, and posterior long hippocampal arteries. Based on the origin of the hippocampal arteries, five types of hippocampal blood supply have been identified. The hippocampal head has six microanatomical layers; those include the condensed pyramidal cell layer also. Hippocampal microvascular supply and perfusion depend on the lumen and structure of the arterioles. Hippocampal microvascular density is comparatively lower than the neocortical cerebral areas.
