Penn study suggests dopamine treatments may play role in increasing impulsivity While approximately one in five Parkinson's disease patients experience impulse control disorder symptoms, the disease itself does not increase the risk of gambling, shopping, or other impulsivity symptoms, according to research from the Perelman School of Medicine at the University of Pennsylvania. A new study is the first to show in a large sample that people with untreated Parkinson's were no more likely to...

April Flowers for redOrbit.com - Your Universe Online A research team from Inserm has published a new study in the journal Biological Psychology detailing the key role played by a protein, the CB1 cannabinoid receptor, during physical exercise. The team demonstrated, in studies conducted on mice, the location of this receptor - in a part of the brain associated with motivation and reward systems - controls the amount of time for which an individual will carry out voluntary physical...

Connie K. Ho for redOrbit.com — Your Universe Online A study by brain researchers at the University of California, Irvine (UCI) recently found that a dopamine-receptor gene variant that is related to personality traits can also impact healthy aging. Their findings were published in the January 2 edition of The Journal of Neuroscience. In the paper, the researchers described how the gene variant, known as DRD4 7R allele, is associated with both active personality traits and longer...

Scientists at Karolinska Institutet in Sweden have identified two molecules that play an important role in the survival and production of nerve cells in the brain, including nerve cells that produce dopamine. The discovery, which is published in the journal Nature Chemical Biology, may be significant in the long term for the treatment of several diseases, such as Parkinson's disease. The same scientists have previously shown that receptors known as "liver X receptors" or LXR, are necessary...

The causes of learning problems associated with an inherited brain tumor disorder are much more complex than scientists had anticipated, researchers at Washington University School of Medicine in St. Louis report. The disorder, neurofibromatosis 1 (NF1), is among the most common inherited pediatric brain cancer syndromes. Children born with NF1 can develop low-grade brain tumors, but their most common problems are learning and attention difficulties. “While one of our top...

In a new study published in the Proceedings of the National Academy of Sciences (PNAS),...

Light instantly triggers or reverses depression-like states in rodents -- NIH-funded studies A specific pattern of neuronal firing in a brain reward circuit instantly rendered mice vulnerable to depression-like behavior induced by acute severe stress, a study supported by the National Institutes of Health has found. When researchers used a high-tech method to mimic the pattern, previously resilient mice instantly succumbed to a depression-like syndrome of social withdrawal and reduced...
