Study suggests nicotine addiction might be controlled by influencing brain mechanisms

There is a clear link between GABA -- a chemical substance of the central nervous system that inhibits neurons in the brain -- and nicotine dependence, according to a study presented today at the American College of Neuropsychopharmacology Annual Meeting. Researchers discovered that nicotine has significant effects on brain GABA, a finding which could potentially help curb the pleasurable effects of nicotine and help people break their addiction to it.

1. Study examines decision-making deficits in older adults
   01-14-2008 · EurekAlert!
   Recent work led by University of Iowa neuroscientist Natalie Denburg, PhD, suggests that for a significant number of older adults, measurable neuropsychological deficits do seem to lead to poor decision-making and an increased vulnerability to fraud. The findings also suggest that these individuals may experience disproportionate aging of a brain region critical for decision-making.

2. Study suggests some brain injuries reduce the likelihood of post-traumatic stress disorder
   12-23-2007 · EurekAlert!
   A new study of combat-exposed Vietnam War veterans shows that those with injuries to certain parts of the brain were less likely to develop post-traumatic stress disorder. The findings, from the National Institutes of Health and the National Naval Medical Center, suggest that drugs or pacemaker-like devices aimed at dampening activity in these brain regions might be effective treatments for PTSD.

3. Early use of nicotine could increase susceptibility for life-long addiction
   10-16-2006 · EurekAlert!
   Nicotine exposure at a young age may alter the "hard-wiring" of the brain that occurs during adolescence and young-adulthood, contributing to future susceptibility for addiction, according to a University of Pittsburgh study.

   08-21-2007 · EurekAlert!
   Scientists at the University of Toronto Mississauga and Queen's University show that genetic variation in the foraging gene results in different tolerance for heat stress and demonstrate how the use of specific drugs can replicate this effect in fruit flies and locusts. While the findings are at an early stage, the researchers suggest that they could lead to ways to rapidly protect the brain from extremely high fevers in mammals, including humans.

   11-14-2006 · EurekAlert!
   According to a new study, septic shock -- a dangerous, often deadly runaway immune response -- is controlled by a genetic on/off switch. The research also suggests how a drug might temper sepsis. This is the first time this genetic mechanism has been revealed in an experimental animal.

   12-19-2006 · EurekAlert!
   How people might play the popular game show -- whether they'd accept an offer for quick cash or hold out for the chance to win $1 million -- probably has less to do with what’s inside each briefcase than what's inside each contestant's brain, suggests a study. While researchers didn't study players of the game, their research in normal adults provides new insight about reward-based decision making and may have implications for understanding and treating addiction.

7. Scripps research study reveals mechanism behind nicotine dependency
   10-01-2007 · EurekAlert!
   Many more people try to quit smoking than succeed in giving up this nicotine-delivering habit. Now, a group of scientists at the Scripps Research Institute has identified one neurobiological mechanism that contributes to nicotine dependence, and to the anxiety and craving experienced upon withdrawal. The findings also suggest a new approach to developing drugs that could help smokers quit.

8. Rhythmic breathing adapts to external beat through 'brain calculus'
   09-11-2007 · EurekAlert!
   A team, led by Chi-Sang Poon, at the Harvard-MIT Division of Health Sciences and Technology, suggests an innate ability to adapt, called nonassociative learning, could be leveraged to design more effective and less costly artificial respirators. In a study published on Sept. 12 in the online, open-access journal PLoS ONE, Poon examined rats under mechanical ventilation to see how they applied different forms of nonassociative learning to adapt to the rhythm imposed by the respirator.

   Preliminary research supported by the National Institute on Drug Abuse (NIDA), a component of the National Institutes of Health, has found that some smokers with damage to a part of the brain called the insula may have their addiction to nicotine practically eliminated.
