Brain's Reward System Responsible For Love, Or Hatred, Of Music
2014-03-06 15:28:39

Brett Smith for redOrbit.com - Your Universe Online While some of us obsess over music – collecting stacks of vinyl and vintage guitars – others could care less. According to a new study, the pleasure we get, or don’t get, from music is based on the innate reward system in our own brain. In the study, which is published in the journal Current Biology, a team of Spanish and Canadian researchers found that some people who feel pleasure in other ways simply can’t get it out of...

Study Explores Cocaine And The Pleasure Principle
2014-03-05 15:10:12

Julie Cohen, University of California - Santa Barbara Researchers use animal models to demonstrate that the net result of cocaine use is a balance of both positive and negative effects On the other side of the cocaine high is the cocaine crash, and understanding how one follows the other can provide insight into the physiological effects of drug abuse. For decades, brain research has focused on the pleasurable effects of cocaine largely by studying the dopamine pathway. But this...

A new study shows that, when properly manipulated, a population of support cells found in the brain called astrocytes could provide a new and promising approach to treat Parkinson's disease. These findings, which were made using an animal model of the disease, demonstrate that a single therapy could simultaneously repair the multiple types of neurological damage caused by Parkinson's, providing an overall benefit that has not been achieved in other approaches. "One of the central...

Stalling Symptoms Of Parkinson's Disease Using Long-term Spinal Cord Stimulation
2014-01-24 11:11:58

Duke University Medical Center Researchers at Duke Medicine have shown that continuing spinal cord stimulation appears to produce improvements in symptoms of Parkinson's disease, and may protect critical neurons from injury or deterioration. The study, performed in rats, is published online Jan. 23, 2014, in the journal Scientific Reports. It builds on earlier findings from the Duke team that stimulating the spinal cord with electrical signals temporarily eased symptoms of the...

Optogenetics Therapy Binge Drinking
2014-01-06 15:09:17

Brett Smith for redOrbit.com - Your Universe Online A team of American researchers has stumbled upon a way to prevent binge drinking in animal subjects, according to a new report in the journal Frontiers in Neuroscience. By using light to stimulate specific neurons in the brain, the study team was able to show a cause-and-effect relationship between the discharge of dopamine in the brain and drinking behaviors of animals. “For decades, we have observed that particular brain regions...

Dopamine-producing cells die as result of cascade triggered by busy enzyme degradation cellular machines Scientists have identified the biological pathway that explains Gaucher disease (GD) patients' higher risk for developing Parkinson's disease (PD), according to research to be presented Tuesday, Dec. 17, at the American Society for Cell Biology annual meeting in New Orleans. GD is a hereditary disease in which the genes that encode the enzyme glucocerebrosidase are mutated, resulting...

MRI Technique Reveals Low Iron In Brains Of ADHD Patients
2013-12-02 08:11:55

Radiological Society of North America Magnetic resonance imaging (MRI) provides a noninvasive way to measure iron levels in the brains of people with attention deficit hyperactivity disorder (ADHD), according to a study being presented today at the annual meeting of the Radiological Society of North America (RSNA). Researchers said the method could help physicians and parents make better informed decisions about medication. ADHD is a common disorder in children and adolescents that can...
