The hippocampus is located in the brain. It plays a crucial role in the formation of memories and is associated with learning and emotions. This structure is part of the limbic system and is primarily involved in consolidating information from short-term memory to long-term memory. The hippocampus is also essential for spatial navigation, helping individuals remember locations and navigate through environments. Damage or dysfunction in this area can lead to significant memory-related issues, such as amnesia, highlighting its importance in cognitive functions and overall mental health.
