Notably, prior presentation of innate-fear stimuli inhibited learned-freezing response, but not vice versa. Whole-brain mapping and pharmacological screening indicated that serotonin-2A receptor (Htr2a)-expressing cells in the central amygdala (CeA) control both innate and learned freezing, but in opposing directions.

This Serotonin and Serotonin Receptors in the Central Auditory System 1 January 1994 | Otolaryngology-Head and Neck Surgery, Vol. 110, No. 1 Roles of brain monoamine neurotransmitters in agonistic behaviour and stress reactions, with particular reference to fish The human brain atlas of the serotonin (5-HT) system does not conform with commonly used parcellations of neocortex, since the spatial distribution of homogeneous 5-HT receptors and transporter is not aligned with such brain regions. This discrepancy indicates that a neocortical parcellation specific to the 5-HT system is needed. Biochemically, the indoleamine molecule derives from the amino acid tryptophan, via the hydroxylation of the 5 position on the ring, and then decarboxylation to produce serotonin. Serotonin is primarily found in the enteric nervous system located in the gastrointestinal tract. However, it is also produced in the central nervous system, specifically in the Raphe nuclei located in the brainstem, Merkel cells located in the skin and taste receptor cells in the tongue. Additionally, serotonin is sto in social hierarchy that allows for priority access.

Serotonin (also known as 5-hydroxytryptamine or 5-HT) is a naturally occurring substance that functions as a neurotransmitter to carry signals between nerve cells (called neurons) throughout your body.

Serotonin is made from the essential amino acid tryptophan Serotonin released in synapse binds with receptor sites triggering an emotional experience until exterior stimulus has stopped. Normally, serotonin is released readily, though due to abnormalities in external or internal stimuli (gene expression, trauma, stress, life events) there may be deficiencies.

2020-07-04 · Serotonin is abundantly found in the brain, bowels, and blood platelets. Typically, serotonin is used to transmit signals between different nerve cells, primarily in the body’s muscles. Moreover, it contributes to the health and well-being and mood of the individual. Serotonin also helps to regulate the sleep-wake cycle of the body.
