The hippocampus (pl.: hippocampi; via Latin from Greek ἱππόκαμπος, 'seahorse'), also hippocampus proper, is a major component of the brain of humans and many other vertebrates. In the human brain the hippocampus, the dentate gyrus, and the subiculum are components of the hippocampal formation located in the limbic system.
Hippocampus anatomy describes the physical aspects and properties of the hippocampus, a neural structure in the medial temporal lobe of each cerebral hemisphere of the brain. It has a distinctive, curved shape that has been likened to the sea-horse creature of Greek mythology , and the ram's horns of Amun in Egyptian mythology .
Regions described in the hippocampus are the head, body, and tail, and other hippocampal subfields include the dentate gyrus, the presubiculum, and the subiculum. The CA subfields use the initials of cornu ammonis, an earlier name of the hippocampus. [1]
The hippocampus, or hippocamp or hippokampos (plural: hippocampi or hippocamps; Ancient Greek: ἱππόκαμπος, from ἵππος, 'horse', and κάμπος, 'sea monster' [1]), sometimes called a "sea-horse" [2] in English, [citation needed] is a mythological creature mentioned in Etruscan, Greek, Phoenician, [3] Pictish and Roman ...
The hippocampus. The hippocampus is a structure in the brain that has been associated with various memory functions. It is part of the limbic system, and lies next to the medial temporal lobe. It is made up of two structures, the Ammon's Horn, and the Dentate gyrus, each containing different types of cells. [1]
The dentate gyrus (DG) is one of the subfields of the hippocampus, in the hippocampal formation.The hippocampal formation is located in the temporal lobe of the brain, and includes the hippocampus (including CA1 to CA4) subfields, and other subfields including the dentate gyrus, subiculum, and presubiculum.
Meta-positron emission tomography (PET) analysis has lent support toward a division of the hippocampus between caudal and rostral regions. [2]Scans have demonstrated a uniform variation in blood flow distribution within the hippocampus (and the medial temporal lobe broadly) during the separate processes of episodic encoding and retrieval.

The hippocampal formation is a compound structure in the medial temporal lobe of the brain. It forms a c-shaped bulge on the floor of the inferior horn of the lateral ventricle. [1] Typically, the hippocampal formation is said to included the dentate gyrus, the hippocampus, and the subiculum. [2]
