The brain is composed of many sections, the Hippocampus being one of those sections. The Hippocampus is responsible for memory. It has been scientifically proven that the Hippocampus continues to generate new neurons, even in adulthood. While other systems do not create new neurons, it is critical that the Hippocampus does. Since the Hippocampus is responsible for processing memories, it needs to generate new neurons so that new memories can be formed. If new neurons were not being produced, then the Hippocampus would not be able to process or store new memories. As humans age memory gets worse, because the hippocampal region of the brain actually shrinks. Older people begin to lose short-term memory first, then long term memory follows.
