Which neurotransmitter is commonly associated with mood regulation?

Serotonin is often highlighted as a key neurotransmitter involved in mood regulation. It plays a significant role in maintaining feelings of well-being and happiness. Low levels of serotonin are frequently linked to mood disorders, such as depression and anxiety. This connection has led to the development of various antidepressant medications that aim to increase serotonin levels in the brain, demonstrating its crucial role in emotional health.

While other neurotransmitters, such as dopamine and norepinephrine, also contribute to mood and emotional states, serotonin’s specific functions in regulating mood make it particularly prominent in discussions surrounding mental health and emotional well-being. Glutamate, primarily known for its role as the main excitatory neurotransmitter in the brain, does not primarily focus on mood regulation.

Overall, serotonin's involvement in various aspects of mood and emotion solidifies its reputation as the neurotransmitter most commonly associated with mood regulation.
