Although heteromeric dopamine receptors composed of both D1 and D2 subunits have been proposed to play a role in depression and schizophrenia, recent studies suggest these heteromers do not exist.

The transgenic mouse, into which was inserted a rare human genetic variation in the dopamine transporter, could lead to improvements in the diagnosis and treatment of these all-too-common brain disorders.

Eating fava beans increases dopamine in blood and urine, but does not stimulate urinary sodium excretion.

Several Vanderbilt researchers have collaborated with this year's Nobel Chemistry winners.

A rare genetic change adds support to the idea that altered dopamine signaling is a key risk factor for ADHD.

Patients with certain autonomic nervous system disorders have impaired odor identification, which could aid in diagnosis.
