Alcohol abuse and dependence are common problems in the United States due to a number of factors, two of which may be social drinking by college students and young adults, and risk taking that may lead to heavier drinking later in life. A study of the neural underpinnings of risk-taking in young, non-dependent social drinkers has found that the caudate nucleus and frontal cortex regions of the brain show less activation in people who drink more heavily. Results will be published in the May...

Researchers say that evolution of human longevity led to both a large brain and brain shrinkage. A team of researchers sought to find out if a chimpanzee brain shrinks as much as a human's brain does with old age. Chet Sherwood, an anthropologist at The George Washington University in Washington, D.C., and a team of scientists from seven other U.S. universities used magnetic resonance imaging (MRI) to measure the space occupied by various brain structures in adult humans and chimpanzee....

Study shows practice may have potential to change brain's physical structure Two years ago, researchers at UCLA found that specific regions in the brains of long-term meditators were larger and had more gray matter than the brains of individuals in a control group. This suggested that meditation may indeed be good for all of us since, alas, our brains shrink naturally with age. Now, a follow-up study suggests that people who meditate also have stronger connections between brain regions and...

As any student who's had to study for multiple exams can tell you, trying to learn two different sets of facts one after another is challenging. As you study for the physics exam, almost inevitably some of the information for the history exam is forgotten. It's been widely believed that this interference between memories develops because the brain simply doesn't have the capacity necessary to process both memories in quick succession. But is this truly the case? A new study by researchers at...

According to scientists, the secret of beauty may lie in the medial orbito frontal cortex, which is the area of the brain just behind the eyes. University College London researchers say it is the part of the brain that lights up when someone encounters something beautiful, depending on tastes. Brain expert Semir Zeki asked 21 young men and women to rate the beauty of a selection of paintings and pieces of music.  The brains were scanned as they viewed and listened to the selections....

Decisions and stress and adolescents, oh my! Stressing out about a boyfriend or girlfriend or history test is part of a typical day for a teenager. But what is making these insignificant events seem like the end of the world? With help from the National Science Foundation (NSF), Adriana Galván, a psychologist at the University of California, Los Angeles (UCLA), has been studying the effects of stress on teenagers and adults. "Teenagers experience stress as more stressful," says...

Although most teens have the knowledge and reasoning ability to make decisions as rationally as adults, their tendency to make much riskier choices suggests that they still lack some key component of wise decision making. Why is this so? Because adolescents may not bother to use those thinking skills before they act. That's the finding of a new study by researchers at Temple University that appears in the journal Child Development. "The study's findings have important implications for debates...

Recording people belting out an old Motown tune and then asking them to listen to their own singing without the accompanying music seems like an unusually cruel form of punishment. But for a team of scientists at the University of California, San Francisco and University of California, Berkeley, this exact Karaoke experiment has revealed what part of the brain is essential for embarrassment. The twist to the experiment was that most of the subjects had neurodegenerative diseases, which helped...

How well our brain functions is largely based on our family's genetic makeup, according to a University of Melbourne led study. The study published in the international publication The Journal of Neuroscience provides the first evidence of a genetic effect on how "Ëœcost-efficient' our brain network wiring is, shedding light on some of the brain's make up. Lead author Dr Alex Fornito from the Melbourne Neuropsychiatry Centre at the University of Melbourne said the findings have...

Less activity found in prefrontal cortex, the 'executive center' of brain By Mark Wheeler, UCLA Tobacco smoking is the leading preventable cause of death and disease in the U.S., with more than 400,000 deaths each year attributable to smoking or its consequences. And yet teens still smoke. Indeed, smoking usually begins in the teen years, and approximately 80 percent of adult smokers became hooked by the time they were 18. Meanwhile, teens who don't take up smoking usually never do. While...
