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...

Brain's Reward System Responsible For Love, Or Hatred, Of Music

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...

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...

This press release is in support of a presentation by Dr. Jocelyne Caboche on Sunday Oct. 6 at the 26th ECNP Congress in Barcelona, Spain The extracellular-signal regulated kinase (ERK) pathway plays a role in multiple drug addictions and appears to modulate neuronal plasticity through epigenetic mechanisms, say French scientists. The discovery could pave the way for new therapeutic options for treating drug addictions, the researchers claim. "The molecular adaptations induced by ERK...

Cocaine Addiction Never Goes Away

Brett Smith for redOrbit.com - Your Universe Online The modern approach to handling an addiction is to recognize it as a disease that cannot be cured – only managed. A new study in the journal Biological Psychiatry reinforces this notion: that a recovering addict is constantly haunted by their days of substance abuse – even after a long period of abstinence. As researchers scramble to answer the 'chicken or the egg' questions surrounding addiction, they are becoming increasingly...

'Odor is a means of chemical communication between mother and child' -- Johannes Frasnelli, University of Montreal What woman has not wanted to gobble up a baby placed in her arms, even if the baby is not hers? This reaction, which everyone has noticed or felt, could have biological underpinnings related to maternal functions. For the first time, an international team of researchers has found evidence of this phenomenon in the neural networks associated with reward. "The olfactory -- thus...

Finding offers clue to developing treatments for misuse of illicit drugs Scientists today reported a possible basis for why food-restricted animals show increased susceptibility to drugs of abuse. This association has puzzled researchers since it was first observed more than three decades ago. Senior author Michael Beckstead, Ph.D., from the School of Medicine at The University of Texas Health Science Center San Antonio, said the team found that dopamine neurons in a brain region called...

Do people get caught in the cycle of overeating and drug addiction because their brain reward centers are over-active causing them to experience greater cravings for food or drugs? In a unique prospective study Oregon Research Institute (ORI) senior scientist Eric Stice, Ph.D., and colleagues tested this theory, called the reward surfeit model. The results indicated that elevated responsivity of reward regions in the brain increased the risk for future substance use, which has never been...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
