New research has uncovered a previously unknown mechanism by which dopamine, a key brain chemical vital for movement and ...

Researchers at Karolinska Institutet, Columbia University and the University of San Francisco, have uncovered a previously ...

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 ...

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 ...

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 ...

Serotonin is one of the primary chemicals that the brain uses to influence mood and behavior, and is a key target for psychiatric drugs. But to aid in the design of improved drugs scientists need to ...

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 ...

Because serotonin is one of the primary chemicals the brain uses to influence mood and behavior, it is also the most common target of psychiatric drugs. To improve those drugs and to invent better ...

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.
