The lateral habenula is hyperactive in rat models of human depression A team of neuroscientists at Cold Spring Harbor Laboratory (CSHL), Brookhaven National Laboratory (BNL) and UC San Diego (UCSD) has collected evidence suggesting that a previously overlooked portion of the brain could be a prime locus of human depression. In two rat models of human depression, the scientists have demonstrated that neurons in a tiny area in the central brain called the lateral habenula (LHb) are...

Speaking directly into a cellphone while holding it against your ear can alter brain activity in those areas closest to the device's antenna, claims a new study published Tuesday in the Journal of the American Medical Association (JAMA). Researchers at the National Institutes of Health (NIH) and the Brookhaven National Laboratory in New York studied 47 adults over the course of a year, using positron emission tomography (PET) to measure their glucose metabolism, or the amount of sugar it...

New study points to a specific brain network that acts as an event monitoring system Wouldn't life be easy if everything happened as we anticipated? In reality, our brains are able to adapt to the unexpected using an inbuilt network that makes predictions about the world and monitors how those predictions turn out. An area at the front of the brain, called the orbitofrontal cortex, plays a central role and studies have shown that patients with damage to this area confuse memories with reality...

The first recordings of individual neurons in adolescent brains during a reward-driven task show that teen brains react with erratic excitement well above adult levels, according to a Journal of Neuroscience report University of Pittsburgh researchers have recorded neuron activity in adolescent rat brains that could reveal the biological root of the teenage propensity to consider rewards over consequences and explain why adolescents are more vulnerable to drug addiction, behavioral...

(Ivanhoe Newswire) "“ By using sophisticated brain imaging, Stanford University School of Medicine researchers are able to predict with 90 percent accuracy which teenagers with dyslexia could improve their reading skills over time. This is the first study to identify specific brain mechanisms involved in a person's ability to overcome reading difficulties. It has potential to lead to new interventions to help dyslexics better learn to read."This gives us hope that we can identify which...

Research from York University is revealing which regions in the brain "fire up" when we suppress an automatic behaviour such as the urge to look at other people as we enter an elevator. A York study, published recently in the journal Frontiers in Human Neuroscience, used fMRI (functional Magnetic Resonance Imaging) to track brain activity when study participants looked at an image of a facial expression with a word superimposed on it. Study participants processed the words faster than the...

Finding could suggest therapies for rebalancing the brain's circuitry in early development Many gene variants have been linked to autism, but how do these subtle changes alter the brain, and ultimately, behavior? Using a blend of brain imaging and genetic detective work, scientists at UCLA's David Geffen School of Medicine and Semel Institute for Neuroscience and Human Behavior are the first to illustrate how genetic variants rewire the brain. Published in the Nov. 3 online edition of Science...

(Ivanhoe Newswire) -- Alcohol, to an adolescent, is usually seen as a rite of passage. Many teenagers view drinking as a gateway into adulthood, or independence. Most teenagers, in the confusion of blissful drunkenness, fail to consider the damages they may be causing their bodies.  A new study shows that both alcohol and marijuana overuse can cause serious detrimental effect on the development of the teenage mind. "The effects of alcohol and marijuana use on cognition in adults have...

Some people may excel at riding a bike, tying a tie, or playing the piano, but those same people may find it difficult to explain or teach those skills to someone else. These motor skills are learned in one part of the brain, whereas classroom instruction and information read in a book are acquired in another area of the brain, explained F. Gregory Ashby, professor and chair of UC Santa Barbara's Department of Psychology. This second area of learning is the frontal cortex "“"“ the...

Repeated exposure to violent television programs and video games can make teenage boys behave more aggressively, according to a new study published online today in the journal Social Cognitive and Affective Neuroscience. According to a press release, Dr. Jordan Grafman and colleagues at the National Institutes of Health's (NIH) National Institute of Neurological Disorders and Stroke recruited 22 14- to 17-year-olds and showed each of them a series of violent clips. The footage used was...
