UVA researchers identify connection between dopamine neurons and brain’s circadian center

Neurons in the brain that produce the pleasure-signaling neurotransmitter dopamine also directly control the brain's circadian center, or "body clock" - the area that regulates eating cycles, metabolism and waking/resting cycles - a key link that possibly affects the body's ability to adapt to jet lag and rotating shift work, a new University of Virginia study has demonstrated.
