Cracking the real Da Vinci Code — what happens in the artist's brain?
The brain of the artist is one of the most exciting workplaces, and now an art historian at the University of East Anglia has joined forces with a leading neuroscientist to unravel its complexities. view more (2006-09-07)
How learning shapes successful decision making in the human brain
New research significantly advances our understanding of the brain mechanisms that link learning with flexible decision making. view more (2009-05-14)
Brain research shows past experience is invaluable for complex decision making
Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have shown that past experience really does help when we have to make complex decisions based on uncertain or confusing information. view more (2009-05-14)
Antidepressants enhance neuronal plasticity in the visual system
In the April 18 issue of Science, scientists from the Scuola Normale Superiore in Pisa, Italy and the Neuroscience Centre at the University of Helsinki, Finland, provide new information about the mechanism of action of antidepressant drugs. view more (2008-04-18)
Infants are able to detect the 'impossible' at an early age
If you've ever been captivated by an M.C. Escher drawing of stairways that lead to nowhere or a waterfall that starts and ends at the same place, then you are familiar with what Psychologists describe as "impossible" objects and scenes. view more (2007-03-20)
Alcoholism-associated molecular adaptations in brain neurocognitive circuits
After many years of heavy drinking, alcohol produces pathological alterations in the brain. In many alcoholics these changes culminate in massive social deterioration and disorders of memory and learning. view more (2008-07-09)
MIT: Computer vision may not be as good as thought
For years, scientists have been trying to teach computers how to see like humans, and recent research has seemed to show computers making progress in recognizing visual objects. A new MIT study, however, cautions that this apparent success may be misleading because the tests being used are inadvertently stacked in favor of computers. view more (2008-01-25)
Prism glasses expand the view for patients with hemianopia
Innovative prism glasses can significantly improve the vision and the daily lives of patients with hemianopia, a condition that blinds half the visual field in both eyes. view more (2008-05-13)
Duke team explains a longtime visual puzzler in new way
A team of neuroscientists at Duke University Medical Center has suggested an entirely new way to explain a puzzling visual phenomenon called the flash-lag effect. view more (2008-10-14)
Glaucoma patients at significantly higher risk for falls, motor vehicle accidents
Persons affected by glaucoma are over three times more likely to have been involved in falls and motor vehicle accidents than persons of the same age without the condition, say researchers from Dalhousie University in Canada. view more (2007-03-01)
How do you teach artists and designers to write?
Although highly adept in the visual domain, art and design students often have difficulty putting their ideas down in writing - a theory supported by a recent report* which found that large numbers of art and design students have many of the difficulties with words normally associated with dyslexia. This problem is now being tackled by Writing... view more... (2003-01-22)
Barrow scientists solve 200-year-old scientific debate involving visual illusions
Neuroscientists at Barrow Neurological Institute at St. Joseph's Hospital and Medical Center have discovered a direct link between eye motions and the perception of illusory motion that solves a 200-year-old debate. view more (2008-11-21)
New insight into addictive behavior offers treatment hope
Addictive behaviour is determined by conscious, rapid thought processes, not necessarily by the content of visual stimuli as previously thought. view more (2009-04-29)
The Glory of a Nearby Star
Optical Light from a Hot Stellar Corona Detected with the VLT The solar corona is a beautiful sight during total solar eclipses. It is the uppermost region of the extended solar atmosphere and consists of a very hot (over 1 million degrees), tenuous plasma of highly ionised elements that emit strong X-ray radiation. There is also a much weaker... view more... (2001-07-31)
'Word-vision' brain area confirmed
Humans have an uncanny ability to skim through text, instantly recognizing words by their shape-even though writing developed only about 6000 years ago-long after humans evolved. view more (2006-04-20)
JHU researcher discovers brain cells have 'memory'
As we look at the world around us, images flicker into our brains like so many disparate pixels on a computer screen that change every time our eyes move, which is several times a second. Yet we don't perceive the world as a constantly flashing computer display. view more (2009-04-03)
UF researchers awaken vision cells in blind mice
University of Florida researchers used gene therapy to restore sight in mice with a form of hereditary blindness, a finding that has bearing on many of the most common blinding diseases. view more (2007-05-22)
Drugs may not delay onset of dementia; and more
Researchers have examined the evidence in favour of giving people considered to be close to developing dementia the drugs that are most commonly used to treat the condition itself. view more (2007-11-27)
Study finds foul owls use feces to show they are in fine feather
Some years ago, within the Department of Conservation Biology of the Estación Biológica de Doñana (EBD-Consejo Superior de Investigaciones Científicas; Seville, Spain), a recently established group (colloquially named the Night Ecology Group) started to explore the possibility of visual communication in crepuscular and... view more...

Penn Medicine pathologists pioneer biomarker test to diagnose or rule out Alzheimer's disease
A test capable of confirming or ruling out Alzheimer's disease has been validated and standardized by researchers at the University of Pennsylvania School of Medicine. view more (2009-03-17)
