Psychologists and neuroscientists generally agree that the hippocampus plays an important role in the formation and indexing of new memories about experienced events. We would not even be able to remember where our house is without the work of the hippocampus.

The hippocampus and amygdala work in concert to consolidate our emotions and long-term memories.
