Hippocampus

The hippocampus is a part of the brain found in mammals. It plays a vital role in memory, learning and navigation. It is found in the medial temporal lobe of the brain and consists of two main parts: the dentate gyrus and the Ammon's horn. It is thought to play an important role in the formation of new memories, retrieval of stored memories and navigation. Damage to the hippocampus can lead to memory deficits, including anterograde amnesia, which is the inability to form new memories. It also plays a role in mood regulation, as well as emotion-related functions such as fear and stress responses. Research into the hippocampus is ongoing and it is a very important part of the brain, requiring further research to better understand its varied roles.
