For first time, PARP-1 enzyme, Sidekick-1 gene implicated in enhancing brain reward system Researchers from the Icahn School of Medicine at Mount Sinai have identified a new molecular mechanism by which cocaine alters the brain's reward circuits and causes addiction. Published online in the journal Proceedings of the National Academy of Sciences by Dr. Eric J. Nestler, MD, PhD, and colleagues, the preclinical research reveals how an abundant enzyme and synaptic gene affect a key reward...

'Love Hormone' Oxytocin May Help Autistic Children Experience Reward
2013-09-12 07:36:37

redOrbit Staff & Wire Reports - Your Universe Online Researchers at the Stanford University have shown that oxytocin, the so-called “love hormone,” is involved in a wider range of social interactions than previously understood, findings that may have implications for neurological disorders such as autism as well as scientific conceptions of our evolutionary heritage. Scientists estimate that the advent of social living preceded the emergence of pair living by about 35 million...

Sex Food Facebook Brain Pleasure Center

Michael Harper for redOrbit.com - Your Universe Online Facebook often gets flak for the way it handles user information and other private data, yet the social networking site still manages to retain over a billion users. Neurologist Dar Meshi of the Free University of Berlin now believes the reason why so many continue to use the services of Facebook is because clicking “like” when viewing photos of friends and maintaining an online reputation triggers responses similar to those of sex...

Research could have direct application for treating human drinking problems A research team led by scientists from the Ernest Gallo Clinic and Research Center at the University of California, San Francisco has identified circuitry in the brain that drives compulsive drinking in rats, and likely plays a similar role in humans. The scientists found they could reduce compulsive drinking in rats by inhibiting key neural pathways that run between the prefrontal cortex, which is involved with...

Michael Harper for redOrbit.com - Your Universe Online One week after the American Medical Association (AMA) declared obesity as a disease, one doctor is suggesting an addiction to food might be a very real thing. Dr. David Ludwig with Boston Children's Hospital admits that the suggestion of a food addiction is very controversial. After all, humans require food to live but don't require other addictive substances, such as alcohol or nicotine to survive. Determined to understand the...

redOrbit Staff & Wire Reports - Your Universe Online Using deep brain stimulation (DBS) in a specific area of the brain appears to reduce caloric intake and lead to weight loss in obese mice prone to binge eating, according to new research published in the Journal of Neuroscience, the official Journal of the Society of Neuroscience. Senior author Tracy L. Bale, an associate professor of neuroscience at the University Pennsylvania's School of Veterinary Medicine's Department of...

Music Activates Same Pleasure Center In The Brain As Sex
2013-04-14 07:40:13

redOrbit Staff & Wire Reports — Your Universe Online Listening to good music can trigger the same reaction in our brains as eating a good meal, taking a psychoactive drug or enjoying an evening of passion, researchers from McGill University in Montreal claim in a new study. The research, which was published in the journal Science, reported the nucleus accumbens is the part of the brain that is most closely associated with the enjoyment a person experiences when listening to a...

Stanford University School of Medicine scientists have laid bare a novel molecular mechanism responsible for the most important symptom of major depression: anhedonia, the loss of the ability to experience pleasure. While their study was conducted in mice, the brain circuit involved in this newly elucidated pathway is largely identical between rodents and humans, upping the odds that the findings point toward new therapies for depression and other disorders. Additionally, opinion leaders...

Deep brain stimulation reduces binge eating in mice, suggesting that this surgery, which is approved for treatment of certain neurologic and psychiatric disorders, may also be an effective therapy for obesity. Presentation of the results will take place Sunday at The Endocrine Society's 94th Annual Meeting in Houston. "Doing brain surgery for obesity treatment is a controversial idea," said the study's presenting author, Casey Halpern, MD, a fifth-year neurosurgery resident physician at...
