Scientists pinpoint pathway that impacts features of autism

A team of scientists at Florida Atlantic University has uncovered a brain-signaling pathway that can be pharmacologically manipulated in genetically engineered mice to reverse an autism-related pathway. Using an investigational ...

Countering the negative effects of a common antidepressant

Selective serotonin reuptake inhibitors, or SSRI's, are popular drugs that treat depression by increasing the amount of a neurotransmitter called serotonin in the brain. But when a common SSRI known as sertraline is taken ...

Antidepressant harms baby neurons in lab-grown 'mini-brains'

Researchers at Johns Hopkins Bloomberg School of Public Health have demonstrated the use of stem-cell-derived "mini-brains" to detect harmful side effects of a common drug on the developing brain. Mini-brains are miniature ...

Scientists aim to learn how serotonin modulates behavior

In popular experience the story of how serotonin modulates the brain might seem simple: pop an antidepressant, serotonin levels go up, mood improves. But neuroscientists acknowledge how little they know about how the neurotransmitter ...

Serotonin

"Serotonin" redirects here. For the professional wrestling stable, see Serotonin.

Serotonin (pronounced /ˌsɛrəˈtoʊnən/) is a monoamine neurotransmitter. It is found extensively in the gastrointestinal tract of animals, and about 80 to 90 percent of the human body's total serotonin is located in the enterochromaffin cells in the gut, where it is used to regulate intestinal movements. The remainder is synthesized in serotonergic neurons in the central nervous system (CNS) where it has various functions, including control of appetite, mood and anger.

Serotonin is found not only in animals, but also in fungi and plants, including fruits and vegetables.
