The Hippocampus is a part of the brain that is responsible for memory formation and navigation. It is named after the seahorse, which it resembles in shape. The term Hippocampus comes from the Greek words hippos, meaning horse, and kampos, meaning sea monster. The Hippocampus is located in the medial temporal lobe of the brain and is composed of two symmetrical structures. It is believed to be involved in the consolidation of short-term memories into long-term memories.
