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.

Engineered cells reveal changes associated with learning, memory and reward

Scientists have created cells with fluorescent dyes that change color in response to specific neurochemicals. By implanting these cells into living mammalian brains, they have shown how neurochemical signaling changes as a food reward drives learning, they report in Nature Methods online October 26. [More]
Early brain imaging studies may help prevent vascular diseases

Early brain imaging studies may help prevent vascular diseases

Future prevention and treatment strategies for vascular diseases may lie in the evaluation of early brain imaging tests long before heart attacks or strokes occur, according to a systematic review conducted by a team of cardiologists, neuroscientists, and psychiatrists from Icahn School of Medicine at Mount Sinai and published in the October issue of JACC Cardiovascular Imaging.

New research shows link between birth season and mood disorders

New research shows link between birth season and mood disorders

New research shows that the season you are born has a significant impact on your risk of developing mood disorders. People born at certain times of year may have a greater chance of developing certain types of affective temperaments, which in turn can lead to mood disorders (affective disorders). [More]
Eating high-protein breakfast reduces food cravings, overeating later on

Eating high-protein breakfast reduces food cravings, overeating later on

According to the Centers for Disease Control and Prevention, many teens skip breakfast, which increases their likelihood of overeating and eventual weight gain. Statistics show that the number of adolescents struggling with obesity, which elevates the risk for chronic health problems, has quadrupled in the past three decades. [More]
Researchers define the process of Parkinson's disease using genetic mouse model

Researchers define the process of Parkinson's disease using genetic mouse model

Parkinson's Disease is the second most common neurodegenerative disorder. In Germany alone, almost half a million people are affected. The focus of the disease is the progressive degeneration of dopamine-producing nerve cells in a certain region of the midbrain, the substantia nigra. Misfolded proteins are the cause. Until recently, it was unclear why damage is confined to specific nerve cells. [More]

AT2101 drug, evaluated for Gaucher disease, slows progression of Parkinson's disease in mice

A new study from UCLA found that a drug being evaluated to treat an entirely different disorder helped slow the progression of Parkinson's disease in mice. [More]
Acacia Pharma reports positive results from APD421 Phase 3 studies for management of PONV

Acacia Pharma reports positive results from APD421 Phase 3 studies for management of PONV

Acacia Pharma announces positive Phase 3 results with APD421 for the management of post-operative nausea & vomiting (PONV). The data generated demonstrated a statistically significant reduction in the incidence of PONV with APD421 compared to placebo in adult surgical patients at moderate to high risk of suffering PONV (PONV is defined as any episode of emesis or use of antiemetic rescue medication in the first 24 hours after surgery).

U-M scientists launch $11.5 million effort to better understand cause of Parkinson's disease

Deep in the brains of the million Americans with Parkinson's disease, changes to their brain cells put them at high risk of dangerous falls -- a problem that resists even the most modern treatments. [More]

People who experience migraine in middle age may develop movement disorders later in life

A new study suggests that people who experience migraine in middle age may be more likely to develop Parkinson's disease, or other movement disorders later in life. Those who have migraine with aura may be at double the risk of developing Parkinson's, according to the study published in the September 17, 2014, online issue of Neurology, the medical journal of the American Academy of Neurology.
