Serotonin exhibits a wide range of functions in both the brain and elsewhere in the body, especially the central nervous system and the gastrointestinal tract. The first known function of serotonin was controlling blood vessel constriction. The brain can’t produce large quantities of serotonin at once, therefore it doesn’t release large quantities of serotonin at once either. In fact, serotonergic neurons have multiple ways of up- and downregulating their serotonin response in order to maintain balance and protect themselves from overstimulation. The pharmaceutical company Eli Lilly set about finding compounds that could selectively target the brain’s serotonin system. And, in 1974, Lilly scientists reported on fluoxetine, a compound that blocks the removal of serotonin — and only serotonin — from synapses. 2020-07-16 · Dopamine and serotonin are both neurotransmitters.

Serotonin system in the brain

Serotonin is a monoamine neurotransmitter also called 5-hydroxytyptamine – or 5-HT. It is derived from the essential amino acid L-tryptophan – ‘essential’ meaning the body can’t create it itself, therefore we need to obtain our 5-HT from the foods we eat. The brain's serotonin system differs between men and women. The scientists who conducted the study think that they have found one of the reasons why depression and chronic anxiety are more common After only four years of problem drinking, a significant decrease in the function of the serotonin system in women’s brains can be seen. This is the system that regulates such functions as impulse control and mood. It takes 12 years before a corresponding decrease is seen in men. Serotonergic fibers project from the raphe nuclei to almost every region of the brain, including the cortex, hippocampus, cerebellum, and midbrain, as well as to the spinal cord.

Its level at the synapse is tightly controlled by the serotonin transporter, which pumps serotonin back into neurons and recycles it for later use. This transporter may be altered in people with autism 6.
