| | '''Serotonin''' is a [[neurotransmitter]] found in the human brain. Serotonin is thought to play an important role in a number of physiological and psychological systems, including [[mood]], body temperature, sleep, and sexuality. For example, individuals with below-average levels of serotonin are vulnerable to disorders such as [[depression]], [[Obsessive-Compulsive Disorder]], [[anxiety|anxiety disorders]], [[bipolar disorder]], [[irritable bowel syndrome]], ear infections, and [[migraine]]s. Consequently, medications that increase serotonergic activity in the brain are often used to treat these disorders. | | '''Serotonin''' is a [[neurotransmitter]] found in the human brain.
