Serotonin, which causes the serotonin receptor to activate, is a neurotransmitter that is most often associated with feeling well, but it also has many other important functions in animal and human life. In depression, the serotonin neuron is conceptualized as having a relative deficiency of the neurotransmitter serotonin. Also, the number of serotonin receptors is up-regulated, or increased, including presynaptic autoreceptors as well as postsynaptic receptors.

Little is understood about how depression makes people feel sad, but neuroscientists do know that the brain chemical serotonin is involved. Today’s antidepressant drugs — such as Prozac (fluoxetine) and Zoloft (sertraline) — are the so-called selective serotonin reuptake inhibitors (SSRIs), which work by increasing serotonin levels in the brain. While the majority of the 15 known receptors for serotonin have been implicated in depression or depressive-like behavior, the serotonin 1A (5-HT 1A) and 1B (5-HT 1B) receptors are among the most Depression is a polygenic and highly complex psychiatric disorder that remains a major burden on society. Antidepressants, such as selective serotonin reuptake inhibitors (SSRIs), are some of the most commonly prescribed drugs worldwide.
