Hippocampus:
Throughout our life we experience events that are worthy of remembering, we have many things that happen in which we wish to never forget. But how do we store these memories, where do they go, what makes us remember? Throughout this paper you will learn about the Hippocampus a part of the brain that forms, and stores memories from our life.

Hippocampus is a part of the brain that’s involved in memory forming, organizing, and storing. It is a limbic system structure that is particularly important in forming new memories and connecting emotions and senses, such as smell and sound, to memories (Buzsaki, Gyorgy). The hippocampus is a horseshoe shaped paired structure that is located within the temporal lobes, and adjacent to the amygdale, there is one on each side of the brain; research has shown that the hippocampus contains cognitive maps in humans. There are place cells in this section of the brain. The patterns of activation of these cells overlap to form mental maps within the hippocampus. The hippocampus' right side is more oriented toward responding to spatial aspects, whereas the left side is associated with other context information. The hippocampus acts as a memory index by sending memories out to the appropriate part of the cerebral hemisphere for long-term storage and retrieving them when necessary. The hippocampus is involved in many different functions of the body such as, Consolidation of New Memories, Emotional Responses, Navigation, and Spatial Orientation (Bailey, Regina).

It is sometimes grouped with the other nearby structures including the denate gyrus and called the “hippocampal formation.” The hippocampus is critical for the formation of new autobiographical and fact memories. It can also function as a memory “gateway” where new memories pass before entering permanent storage in the brain. Hippocampal damage can result in anterograde amnesia which is loss of the ability to form new memories, although the...
