Falls and balance problems may be early indicators of Alzheimer's disease, researchers at Washington University School of Medicine in St. Louis report July 17, 2011, at the Alzheimer's Association International Conference on Alzheimer's Disease in Paris. Scientists found that study participants with brain changes suggestive of early Alzheimer's disease were more likely to fall than those whose brains did no ...

An existing anti-seizure drug improves memory and brain function in adults with a form of cognitive impairment that often leads to full-blown Alzheimer's disease, a Johns Hopkins University study has found. The findings raise the possibility that doctors will someday be able to use the drug, levetiracetam, already approved for use in epilepsy patients, to slow the abnormal loss of brain function in some agi ...

Your brain works hard to help understand your fellow person – no matter how different they may be. According to a new study from USC, even failing to possess a full complement of limbs will not stop your brain from understanding what it is like for someone else to experience pain in one of them. It may, however, change the way your brain does so. ...

Binge or "heavy episodic" drinking is prevalent during adolescence, raising concerns about alcohol's effects on crucial neuromaturational processes during this developmental period. Heavy alcohol use has been associated with decrements in cognitive functioning in both adult and adolescent populations, particularly on tasks of spatial working memory (SWM). This study examined gender-specific influences of bi ...

Ever get the heebie-jeebies at a wax museum? Feel uneasy with an anthropomorphic robot? What about playing a video game or watching an animated movie, where the human characters are pretty realistic but just not quite right and maybe a bit creepy? If yes, then you've probably been a visitor to what's called the "uncanny valley." The phenomenon has been described anecdotally for years, but how and why this h ...

Infants born prematurely are at risk for injuries to the white and gray matter of the brain that affect cortical development and neural connectivity. Certain forms of these injuries can be detected in the neonatal period using ultrasound, according to Columbia University Medical Center researchers. Researchers who followed a group of premature infants until age 16 found that those with neonatal ultrasound a ...

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 regi ...

Certain brain injuries can cause people to lose the ability to visually recognize objects — for example, confusing a harmonica for a cash register. Neuroscientists from Carnegie Mellon University and Princeton University examined the brain of a person with object agnosia, a deficit in the ability to recognize objects that does not include damage to the eyes or a general loss in intelligence, and have uncove ...

Visual and tactile objects in our surroundings are translated into a perception by complex interactions of neurons in the cortex. The principles underlying spatial and temporal organization of neuronal activity during decision-making and object perception are not all understood yet. Jason Kerr from Max Planck Institute for Biological Cybernetics in Tübingen, in collaboration with Winfried Denk from the Max ...

Siblings of people with autism show a similar pattern of brain activity to that seen in people with autism when looking at emotional facial expressions. The University of Cambridge researchers identified the reduced activity in a part of the brain associated with empathy and argue it may be a 'biomarker' for a familial risk of autism. The Medical Research Council funded study is published today, 12th July, ...
