Serotonin is often referred to as the "happiness molecule." It plays a critical role in affecting mood levels and is also a neurotransmitter that sends signals within the brain and the body.

Serotonin in depression is highly relevant in diagnosis, treatment, and drug development. To better study this area, a team has now developed a fluorescent probe for imaging processes that is highly ...

This feel-good hormone plays a key role in everything from sleep and digestion to happiness and contentment—here's how to keep it flowin'. Serotonin is a “feel-good” hormone, or neurotransmitter, that ...

Since the 1960s, researchers have postulated that major depression stems from disruptions in the serotonin neurotransmitter system, but the evidence for that idea, though plentiful, was indirect. In ...

These imaging studies suggest that the serotonin level in the model for depression is not the primary factor. The ability of neurons to release serotonin seems far more critical. This ability ...

Serotonergic neurons release serotonin when they sense high levels of glucose. This triggers the activation of the kisspeptin neurons, the primary stimulator for releasing reproductive hormones.

Scientists have uncovered a powerful strategy that the brain uses to coordinate chemical signaling. In a new study, researchers found that in the striatum, a brain region central to learning and ...

Depression is a common mental health condition that continues to challenge researchers and clinicians in the quest for effective treatments. Serotonin, a neurotransmitter often associated with mood ...

Serotonin (5-hydroxytryptamine, 5-HT) is a key modulator of gut function, orchestrating motility, secretion and visceral sensitivity. More than 90 % of the body’s serotonin is synthesised by ...
