What part of your brain affects moods?

The limbic system, particularly the amygdala and hippocampus, plays a crucial role in regulating moods. The amygdala is involved in processing emotions such as fear and pleasure, while the hippocampus is important for forming memories and emotional responses. Additionally, neurotransmitters like serotonin and dopamine, which are produced in various brain areas, significantly influence mood regulation. Dysfunction in these regions or imbalances in neurotransmitters can lead to mood disorders.
