This hormone impacts your entire body. It enables brain cells and other nervous system cells to communicate with each other. Serotonin also helps with sleeping, eating, and digestion. However, if the brain has too little serotonin, it may lead to Serotonin is a chemical your body produces that's needed for your nerve cells and brain to function.

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. Serotonin is a neurotransmitter that’s partly responsible for feelings of happiness and for mood regulation in humans. This makes it a common target for antidepressants, which block serotonin from being reabsorbed by neurons after it has dispatched its signal, so more of it stays floating around the brain.

Serotonin system in the brain

The brain-gut axis is a bidirectional communication system between the central nervous system and the gastrointestinal tract.

Serotonin's influence on mood makes it one of several brain chemicals that are integral to your overall sense of well-being. These are the dopamine transporter (DAT), serotonin transporter (SERT), and the norepinephrine transporter (NET) in the outer cell membrane and the vesicular monoamine transporter (VMAT1 and VMAT2) in the membrane of intracellular vesicles. Girls seem to be particularly hard hit by these serotonin fluctuations, perhaps because rising levels of sex hormones, especially estrogen, are linked to the regulation of serotonergic pathways in the brain (Bethea, Lu, Gundlah, & Streicher, 2002). Figure 1.5 illustrates the dopamine and serotonin pathways in the brain.

LSD appears to act through a particular receptor called 5-HT 2A R. To gain insights into LSD’s effects, a research team led by Dr. Bryan Roth at the University of North Carolina crystallized a related receptor, 5-HT 2B R, attached to LSD. Serotonin, or 5-hydroxytryptamine (5-HT), is a well-known neurotransmitter that plays vital roles in neural activities and social behaviors.

Within the cell bodies of serotonergic neurons, serotonin is produced from the essential amino acid l -tryptophan in a two-step process. To reiterate, serotonin prefers binding the receptor 1A in the limbic system. The brain is on a passive coping mode by default. Low brain serotonin then means less activity of receptor 2A in the That is to say, low levels of serotonin are correlated with high levels of aggression.
