Cognitive impairment in people with AIDS exists in two forms

The researchers say their findings indicate there probably are two separate mechanisms that can cause cognitive impairment in people with AIDS.

Scientists gauge pain in premature babies

Scientists at UCL (University College London) have measured responses to pain in the brains of premature babies and have shown that they are likely to experience ‘true’ pain rather than simply displaying reflex reactions.

Study demonstrates decreased neural specialization in the ventral visual cortex in older adults

One of two separate areas of the brain light up when younger people look at a house or a face, but each image activates both areas of the brain at the same time in older persons

Functional magnetic resonance imaging can predict effectiveness of cognitive behavior therapy for treating depression

Whether or not cognitive behavior therapy (CBT) will help a person recover from depression can be predicted through brain imaging, according to research results published by the University of Pittsburgh School of Medicine in the April issue of the American Journal of Psychiatry.

People with very agile minds tend to have a very agile cortex

Youth with superior IQ are distinguished by how fast the thinking part of their brains thickens and thins as they grow up, researchers at the National Institute of Mental Health (NIMH) have discovered.

Enzymes that harm brain immediately after stroke may be beneficial days later

Insights from the study could change the way stroke is treated, extending the window for effective treatment from a couple of hours to a couple of weeks. The results may suggest new ideas for drug development.

Scans show smart kids have different brains

Researchers say that children who perform differently in IQ tests show different patterns of brain development.

Study shows patients regain hand function when given cortical stimulation with rehab

Sending tiny electric pulses to a part of the brain controlling motor function helps ischemic stroke survivors regain partial use of a weakened hand, new Oregon Health & Science University research shows.

Effects of energy drink ingestion on alcohol intoxication

The combined use of alcohol and "energy drinks" such as Red Bull. have become increasingly popular among youth and young adults in recent years. Users often report reduced sleepiness and increased sensations of pleasure.

Early risk, attention and brain activation in adolescents born preterm

In one of the first studies to use brain imaging with adolescents born prematurely, New Jersey researchers report that the effects of premature birth and environmental risks on the brain during the first three years of childhood continue through adolescence.

Researchers find potential new mechanism for how the brain's reward system works

Amid reports that a drug used to treat Parkinson's disease has caused some patients to become addicted to gambling and sex, University of Pittsburgh researchers have published a study that sheds light on what may have gone wrong.

Inhibiting gamma secretase may prevent amyloid plaque build-up thought to trigger Alzheimer's disease

Oregon Health & Science University is participating in a national study of a drug that may prevent Alzheimer's disease by blocking an enzyme that produces plaques believed to trigger the disorder.

Gene linked to impulsive violence weakens brain circuits that regulate thinking in humans

A version of a gene previously linked to impulsive violence appears to weaken brain circuits that regulate impulses, emotional memory and thinking in humans, researchers at the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) have found.

Researchers aim to understand how babies' learning is linked to their neurological development

Psychologists at the University of Manchester have set up a 'BabyLab' within the University, to try and learn more about how babies acquire knowledge.

Patterns of fMRI activity dissociate overlapping functional brain areas that respond to biological motion

A swaying tree and a moving person activate distinctive areas of the brain's visual cortex, since recognizing people is essential for social interaction. So, an important question in exploring the visual system is how the visual cortex manages such specific recognition of "biological motion."

Link between genetic variation and outcome of antidepressant treatment

Whether depressed patients will respond to an antidepressant depends, in part, on which version of a gene they inherit, a study led by scientists at the National Institutes of Health (NIH) has discovered.

New AF267B drug reverses key cognitive deficits, pathology in Alzheimer's

A new drug that enhances the activity of a key brain cell receptor involved in Alzheimer's disease (AD) reverses learning and memory deficits in mice engineered to have pathological hallmarks of the disease.

Research challenges theories on the organization of the visual system

Neuroscientists from the University of Washington and the University of Minnesota have found that the first area in the cortex of the human brain that receives information from the eyes processes the perceived size, rather than the actual size, of an object.

Researchers find compound that interferes with the pathogenic effects of Huntington's disease

There is no cure for Huntington's, a neurodegenerative disorder that now afflicts 30,000 Americans, with another 150,000 at risk. The fatal disease, which is genetically inherited, usually strikes in midlife and causes uncontrolled movements, loss of cognitive function and emotional disturbance.
