Researchers at the University of Illinois at Chicago have shown for the first time that damage to a particular area of the brain and a consequent reduction in noradrenaline are associated with multiple sclerosis. The study is available online in the journal Brain. The pathological processes in MS are not well understood, but an important contributor to its progression is the infiltration of white blood cells involved in immune defense through the blood-brain barrier. Douglas Feinstein,...

Investigators Build a Case Linking Chemical DOPAL to Illness In new research from Saint Louis University, investigators have found evidence that a toxin produced by the brain is responsible for the series of cellular events that lead to Parkinson's disease. The study, published in PLoS One, found that the brain toxin DOPAL plays a key role in killing the dopamine neurons which trigger the illness. In earlier research, Saint Louis University investigators found that DOPAL seemed to be...

A Montreal study reports that dopamine is released in the brain by those who become euphoric over listening to music, along with food, money and psychoactive drugs. McGill University researchers in Montreal, Canada recruited eight volunteers aged 19-24 who responded to advertisements requesting people who experienced "chills" -- a marker of extreme pleasure, when listening to music. Listening to their favorite piece of spine-tingling music, the eight volunteers showed a rush of physical...

New findings on how rats make choices may provide insights into addiction and impulse-driven behavior Researchers have shed new light on dopamine's role in the brain's reward system, which could provide insight into impulse control problems associated with addiction and a number of psychiatric disorders. A joint study by the University of Michigan and University of Washington found that, contrary to the prevailing conception, differences in individuals' styles of response to environmental...

Neuroscientists at the Centre for Addiction and Mental Health (CAMH) have developed a protein peptide that may be a novel type of highly targeted treatment for depression with a low side-effect profile. Depression affects one in ten Canadians at some time in their lives and is a leading cause of disability worldwide. The study published in this month's Nature Medicine found that coupling between two dopamine receptors was significantly elevated in the brains of people who had been diagnosed...

Researchers at the University of Copenhagen have succeeded in creating a model of the way the brain releases dopamine, an important chemical involved in transmitting signals between nerve cells. The model, the product of an interdisciplinary collaboration, will be an important tool in helping scientists understand how we learn and how the brain perceives reward and punishment. It is hoped that the model can be used to understand drug addiction and in the treatment of schizophrenia. In the...

Concordia research looks at role of dopamine in the rhythms of daily behavior; may have impact on activity and sleep rhythms in Parkinson's disease Daily sleeping and eating patterns are critical to human well-being and health. Now, a new study from Concordia University has demonstrated how the brain chemical dopamine regulates these cycles by altering the activity of the "clock-protein" PER2. Published in the Journal of Neuroscience, these findings may have implications for individuals with...

Scientists at the Naval Research Laboratory (NRL) in conjunction with the Scripps Research Institute in La Jolla, Ca., recently reported a detailed study of the interactions of water soluble semi-conductor quantum dots (QDs) with the electro-active neuro-transmitter dopamine. These biocompatible QD-dopamine nano-assemblies may be used as the active component for sensors that are used to detect a wide variety of target analytes ranging from sugars to peroxides. According to NRL's Dr. Michael...

New animal research demonstrates diet-induced changes in brain chemical release Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, finds that prolonged exposure to a high fat diet is correlated with changes in the brain chemical dopamine within the striatum, a critical component of the brain's reward system.  The authors measured...

Brain study highlights role of dopamine in impulsive behavior It's a common scenario: you're on a diet, determined to give up eating cakes, but as you pass the cake counter, all resolve disappears"¦ Now, scientists at the Wellcome Trust Centre for Neuroimaging at UCL (University College London) have shed light on the brain processes that affect our will power and make us act impulsively. In a study published today in the Journal of Neuroscience, funded mainly by the Wellcome Trust,...
