Dopamine News and Research RSS Feed - Dopamine News and Research

Dopamine is a hormone and neurotransmitter occurring in a wide variety of animals, including both vertebrates and invertebrates. In the brain, this phenethylamine functions as a neurotransmitter, activating the five types of dopamine receptors — D1, D2, D3, D4 and D5, and their variants. Dopamine is produced in several areas of the brain, including the substantia nigra and the ventral tegmental area. Dopamine is also a neurohormone released by the hypothalamus. Its main function as a hormone is to inhibit the release of prolactin from the anterior lobe of the pituitary. Dopamine has many functions in the brain, including important roles in behavior and cognition, motor activity, motivation and reward, inhibition of prolactin production (involved in lactation), sleep, mood, attention, and learning. Dopaminergic neurons (i.e., neurons whose primary neurotransmitter is dopamine) are present chiefly in the ventral tegmental area (VTA) of the midbrain, substantia nigra pars compacta, and arcuate nucleus of the hypothalamus.

Scientists identify microrna that provides clues for quieting auditory hallucinations of schizophrenia

St. Jude Children's Research Hospital scientists have identified a small RNA (microRNA) that may be essential to restoring normal function in a brain circuit associated with the "voices" and other hallucinations of schizophrenia. [More]
Gene mutation appears to increase risk of Parkinson's disease in Caucasians

Gene mutation appears to increase risk of Parkinson's disease in Caucasians

A defect in a gene that produces dopamine in the brain appears to accelerate the onset of Parkinson's disease, according to new research from Iowa State University. The effect is particularly dramatic for people under age 50. [More]

Pharmacological therapy combined with a rehabilitation program that teaches how to compensate for memory and attention problems offers new hope for people who suffer the consequences of traumatic brain injury. [More]
TSRI scientists discover precise signaling mechanisms that regulate brain’s motor function

TSRI scientists discover precise signaling mechanisms that regulate brain’s motor function

In new findings that could have an impact the development of therapies for a number of currently untreatable brain disorders such as Parkinson’s and Huntington’s diseases, scientists from the Florida campus of The Scripps Research Institute (TSRI) have found, for the first time, that a specific signaling circuit in the brain is deeply involved in motor activity.

Researcher develops nature-inspired adhesive that stays sticky when wet

Even the strongest glues collapse when soaked. Just watch a band-aid slide ungracefully off a finger or toe while in the shower. However, with support from the Office of Naval Research, one researcher has developed a nature-inspired adhesive that stays sticky when wet. [More]
Study reveals way to actively reverse anesthetic-induced unconsciousness

Study reveals way to actively reverse anesthetic-induced unconsciousness

The latest study from a Massachusetts General Hospital/Massachusetts Institute of Technology team investigating the mechanisms underlying general anesthesia finds that stimulating a specific group of neurons in mice produces signs of arousal -- including getting on their feet and walking -- even as the animals continue to receive the anesthetic drug isoflurane.

Researchers find new way to rapidly awaken patients after general anesthesia

Researchers find new way to rapidly awaken patients after general anesthesia

The use of general anesthesia for surgery has not changed fundamentally since it was first introduced 170 years ago. Patients are still left to come around in their own time following withdrawal of the drug. [More]
