Monoamines are a group of neurotransmitters that play a crucial role in transmitting signals in the brain. They include important chemicals such as serotonin, dopamine, and norepinephrine. These neurotransmitters are derived from amino acids and are involved in regulating mood, emotions, and various bodily functions. The balance of monoamines is essential for mental health. For instance, low levels of serotonin are often linked to depression, while dopamine is associated with pleasure and reward. Medications that target monoamine levels, such as antidepressants, aim to restore this balance and improve mental well-being.
