Limbic system 11 November 2024 09:55 Limbic system Emotion: Controls feelings like fear, anger, happiness, and love. Memory: Important for forming and retrieving long-term memories (especially emotional memories). Motivation and Reward: Drives actions related to survival (like eating and reproduction). Learning: Helps link experiences with emotional significance, which strengthens memory.
