What is Serotonin?

  Serotonin (5-hydroxytryptamine, or 5-HT) is a monoamine neurotransmitter synthesized in serotonergic neurons in the Central Nervous System (CNS) and enterochromaffin cells (Kulchitsky) in the gastrointestinal tract of animals and humans.

Serotonin is also found in various fungi and plants including fruit and vegetales.1

In the central nervous system, it is believed that serotonin plays an important role as a neurotransmitter in the inhibition of: anger, aggression, body temperature, mood, sleep, vomiting and appetite.

These inhibitions are directly related symptoms depression. Particularly, antidepressants deal alter serotonin levels in the individual.

Besides, serotonin is also a peripheral signal mediator. For example, serotonin is found extensively in the gastrointestinal tract (about 90%), and the main store 2 are platelets in blood circulation.

What is serotonin


Like all neurotransmitters, the effects of 5-HT in human mood and mental state, and its role in consciousness, are very difficult to determine.

Among the main serotonin functions is to regulate appetite by satiety, controlling body temperature, and motor activity and cognitive functions perceptual.

Serotonin is involved in other known neurotransmitters such as dopamine and noradrenalin, which they are related anguish, anxiety, fear, aggression and eating problems.

Serotonin is also necessary for produce melatonin (sleep-inducing), a non-protein hormone that is produced in the brain in Pineal gland, and it is responsible for the sleep regulation.

main functions of serotonin in our body

serotonin sunset increases as from it melatonin is synthesized in the pineal gland at night. Melatonin decreases at dawn, when synthesis is inhibited, thereby increasing serotonin (which is not transformed melatonin).

Another important function of this neurotransmitter, is acting as the internal clock of our body, which in turn determines our cycles of sleep and wakefulness.

The internal clock It is responsible for coordinating vAryan biological functions such as body temperature, stress hormone, cortisol, and sleep cycles.

Proper coordination of these four elements makes us sleep soundly and wake up rested. Men produce up to 50% more serotonin than women, Thus, these are more sensitive to changes in serotonin levels.

Serotonergic function is primarily inhibitory. Influences on sleep and is also related to the moods, emotions and depressive states.

It affects vascular function and the heart beat frequency.
Regulates the secretion of hormones, such as growth. Changes in the level of this substance are associated with mental imbalances such as schizophrenia or infantile autism.

It also plays an important role in Obsessive Compulsive Disorder, an anxiety disorder. Some hallucinogenic mushrooms, LSD and MDMA serotonínicos act strongly in recipients.

Among the physiological functions of serotonin stresses inhibition of gastric secretion, stimulation of smooth muscle and hormone secretion by the pituitary.

Low levels of serotonin in people with fibromyalgia partly explain why pain and sleep problems.

These low levels are also associated with aggressive states, depression and anxiety and even migraines, because when serotonin levels fall, the blood vessels to dilate.
