By testing formerly blind patients within weeks of sight restoration, Sinha and his colleagues found that subjects had very limited ability to distinguish an object from its background, identify overlapping objects, or even piece together the different parts of an object.

A difference in brain activity patterns may explain why some people are able to maintain a significant weight loss while others regain the weight, according to a new study by researchers with The Miriam Hospital.

Blame your brain for sabotaging your efforts to get back on track after splurging on an extra scoop of ice cream or that second burger during Friday night's football game.

Brainetics scam is rising to the top of the search engines and Google trends today. Last year, Mike Byster created the popular Brainetics educational system that teaches math and memory skills. It was
quickly awarded a 2008 Parents' Choice Gold Award but now the rumor on several blogs and social networks is that Brainetics is a scam.

The belief that healthy older brains are substantially smaller than younger brains may stem from studies that did not screen out people whose undetected, slowly developing brain disease was killing off cells in key areas, according to new research. As a result, previous findings may have overestimated atrophy and underestimated normal size for the older brain.

In a finding that sheds new light on the neural mechanisms involved in social behavior, neuroscientists at the California Institute of Technology (Caltech) have pinpointed the brain structure responsible for our sense of personal space.

Schizophrenia waits silently until a seemingly normal child becomes a teenager or young adult. Then it swoops down and derails a young life.

Professor Declan Murphy and colleagues Dr Michael Craig and Dr Marco Catani from the Institute of Psychiatry at King's College London have found differences in the brain which may provide a biological explanation for psychopathy. The results of their study are outlined in the paper 'Altered connections on the road to psychopathy', published in Molecular Psychiatry.

Scientists at Duke University and the University of North Carolina have devised a chemical technique that promises to allow neuroscientists to discover the function of any population of neurons in an animal brain, and provide clues to treating and preventing brain disease.

New imaging research in the June 24 issue of The Journal of Neuroscience helps explain why sleep deprivation affects some people more than others. After staying awake all night, those who are genetically vulnerable to sleep loss showed reduced brain activity, while those who are genetically resilient showed expanded brain activity, the study found. The findings help explain individual differences in the ability to compensate for lack of sleep.

People make value judgements about others based on their facial expressions. A new study, carried out be Spanish and Brazilian researchers, shows that – after looking at a face for only 100 milliseconds – we can detect expressions of happiness and surprise faster than those of sadness or fear.

Autopsy results have revealed that Natasha Richardson, 45, died of blunt force trauma to her brain.
