What is the hippocampus responsible for?

• A. Language
• B. Memory
• C. Balance
• D. Sleep

Answer: (B)

The hippocampus is primarily involved in memory formation and consolidation. It helps encode and store new declarative memories—facts and events—and supports spatial memory so you can remember places and navigate environments. When you experience something new, the hippocampus briefly holds and organizes that information and works to transfer it into longer-term storage in the surrounding cortex, a process that often unfolds during rest and sleep. Damage to this area can make it hard to form new memories while older memories and other cognitive functions may remain intact. While memory is its main role, other brain regions handle language, balance, and sleep, though sleep does support memory consolidation via hippocampal activity.
