What is the role of the hippocampus in memory?

The hippocampus plays a vital role in the formation of new memories and learning processes. It is a key structure in the brain's limbic system and is primarily involved in the consolidation of information from short-term memory to long-term memory. When you encounter new information or experiences, the hippocampus helps to encode and store these memories so that they can be retrieved later. This process is essential for various types of learning, including episodic memory (memories of personal experiences) and declarative memory (facts and information).

While the hippocampus is also associated with aspects of spatial awareness—helping to navigate and understand physical space—its primary and most critical function pertains to the formation of new memories. As a result, this link to memory and learning makes the correct answer not only valid but central to the understanding of how our memory system operates.
