The hippocampus is a part of the forebrain, located in the medial temporal lobe. It belongs to the limbic system and plays major roles in long term memory and spatial navigation.
The hippocampus is a small area of the brain that is located in the medial temporal lobe of the brain. It is comprised of two halves, one which resides on each hemisphere of the brain. It is generally agreed that the main functionality of the hippocampus encompasses the creation of new memories, the formation of long term memory, and spatial navigation. Inside the hippocampus resides the amygdala. The amygdala is a part of the brain which has previously been linked with depression. Studies in the past have suggested a direct relationship between a shrinkage in the hippocampus and depression, but the sample size of previous studies hasnât been large enough to yield definitive results.
