How are memories retrieved? The part of the brain called the "hippocampus" is believed to be integral in this process. This region of the cerebrum has a broad S-shaped sweep; its elegant curvature reminded classical anatomists of a seahorse, so it was given the Greek name for that creature. One type of memory that the hippocampus mediates is "declarative memory," which we experience when we consciously reach back in our minds for previous experiences. The hippocampus also appears to contribute to the linking of objects and events around us with past experiences.
