Hippocampus

Hippocampus (/hɪˈpɒkəmpəs/; from the Greek hippos meaning "horse" and kampos meaning "sea monster") is a major component of the brain in humans and other vertebrates. It belongs to the limbic system and plays important roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation.

Etymology

The term "hippocampus" is derived from the Greek words hippos (ἵππος), meaning "horse," and kampos (κάμπος), meaning "sea monster," as the structure's shape in cross-section resembles that of a sea-horse.

Anatomy

The hippocampus is located in the medial temporal lobe of the brain, underneath the cortical surface. It contains two main interlocking parts: the hippocampus proper (also called Ammon's horn) and the dentate gyrus.

Function

The hippocampus is involved in memory forming, organizing, and storing. It's a part of the limbic system, and is involved in many brain functions related to behavior, memory, and emotions.
