Attack by own immune system may kill neurons in Parkinson's disease The cause of neuronal death in Parkinson's disease is still unknown, but a new study proposes that neurons may be mistaken for foreign invaders and killed by the person's own immune system, similar to the way autoimmune diseases like type I diabetes, celiac disease, and multiple sclerosis attack the body's cells. The study was published April 16, 2014, in Nature Communications. "This is a new, and likely controversial,...

MONTREAL, April 3, 2014 /CNW Telbec/ - Bruno Giros, PhD, a researcher at the Douglas Mental Health University Institute and a professor in the Department of Psychiatry at McGill University, has demonstrated, for the first time, the role that dopamine plays in a region of the brain called the hippocampus. Published in Biological Psychiatry, this discovery opens the door to a better understanding of psychiatric diseases, such as schizophrenia. Dopamine is a neurotransmitter that plays...

Commonly used neurological medication proves successful at blocking brain's reward system triggers Relapse is the most painful and expensive feature of drug addiction—even after addicted individuals have been drug-free for months or years, the likelihood of sliding back into the habit remains high. The National Institute on Drug Abuse estimates that 40 to 60 percent of addicted individuals will relapse, and in some studies the rates are as high as 80 percent at six months after...

Memories are difficult to produce, often fragile, and dependent on any number of factors—including changes to various types of nerves. In the common fruit fly—a scientific doppelganger used to study human memory formation—these changes take place in multiple parts of the insect brain. Scientists from the Florida campus of The Scripps Research Institute (TSRI) have been able to pinpoint a handful of neurons where certain types of memory formation occur, a mapping feat that one day...

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...
