Dr. Drew would never say it like that.

"The hippocampus is a brain structure which lies under the medial temporal lobe, one on each side of the brain. It is sometimes grouped with other nearby structures including the dentate gyrus and called the "hippocampal formation." The hippocampus is critical for the formation of new autobiographical and fact memories. It may function as a memory "gateway" through which new memories must pass before entering permanent storage in the brain. Hippocampal damage can result in anterograde amnesia: loss of ability to form new memories, although older memories may be safe. Thus, someone who sustains an injury to the hippocampus may have good memory of his childhood and the years before the injury, but relatively little memory for anything that happened since."
