Size of brain areas does matter — but bigger isn't necessarily better
The ability to hit a baseball or play a piano well is part practice and part innate talent. One side of the equation required for skilled performances has its roots in the architecture of the brain genetically determined before birth, say scientists at the Salk Institute for Biological Studies. Practice takes no explaining, just persistence. view more (2007-03-02)
'Speed of thought' guides brain's memory consolidation
Scientists at The University of Arizona have added another piece of the puzzle of how the brain processes memory. view more (2007-11-16)
MIT researcher presents new view of how the cortex forms
A leading neuroscientist at MIT and one from the University of California at San Francisco (UCSF) report in the Nov. 4 special issue of Science dedicated to the brain that the controversy is over: The "protomap" and "protocortex" theories of brain development are dead. view more (2005-11-14)
Unusual data shed new light on brain and inhibiting behavior
When a child has a problem focusing or acts too quickly with inappropriate behavior, it's enough to drive adults nuts. view more (2006-08-16)
Looking at language
The study of the neural basis of language has largely focused on regions in the cortex - the outer brain layers thought by many researchers to have expanded during human evolution. view more (2009-08-05)
Growth factors and environment combine to increase brain maturation
A new study showing that growth factors and the environment combine to increase brain maturation appears in the May 30th issue of the online, open-access journal PLoS ONE. view more (2007-05-30)
Seeing two figures in coordinated action helps brain pick out movements of one
A new study by vision scientists at the University of California, Berkeley, finds that the human visual system is better able to discriminate the movements of a single person when his or her actions are coordinated in a meaningful way with a second individual. view more (2006-09-08)
Stress-related disorders affect brain's processing of memory
Researchers using functional MRI (fMRI) have determined that the circuitry in the area of the brain responsible for suppressing memory is dysfunctional in patients suffering from stress-related psychiatric disorders. Results of the study will be presented today at the annual meeting of the Radiological Society of North America (RSNA). view more (2008-12-03)
UCSD team creates model for genetic brain syndrome
Researchers at the University of California, San Diego (UCSD) School of Medicine took a step closer to understanding the basis of a severe epilepsy and mental retardation syndrome. view more (2006-01-05)
A molecule that protects from neuronal disorders
Many neuronal disorders, including epilepsy, schizophrenia and lissencephaly - a form of mental retardation -, result from abnormal migration of nerve cells during the development of the brain. view more (2007-09-17)
Hidden cues that make smokers light up
Smokers trying to kick the habit for 2004 are probably finding it much harder than they expected. New research by University of Sussex psychologists reveals that smokers subconsciously react to all sorts of visual cues that encourage them to light up. It's not just the obvious sight or smell of a cigarette that sparks off the behaviour. The... view more... (2004-01-14)
Electronic chip, interacting with the brain, modifies pathways for controlling movement
Researchers at the University of Washington (UW) are working on an implantable electronic chip that may help establish new nerve connections in the part of the brain that controls movement. view more (2006-10-25)
Schizophrenia: Delusion without illusion
Scientists have discovered that schizophrenia sufferers are not fooled by a visual illusion and are able to judge it more accurately than non-schizophrenic observers. view more (2005-10-25)
Despite darkness, nocturnal bees learn visual landmarks while foraging at night
Day-active bees, such as the honeybee, are well known for using visual landmarks to locate a favoured patch of flowers, and to find their way home again to their hive. Researchers have now found that nocturnal bees can do the same thing, despite experiencing light intensities that are more than 100 million times dimmer than daylight. The new... view more...

Brain cells work differently than previously thought
Scientists know that information travels between brain cells along hairlike extensions called axons. For the first time, researchers have found that axons don't just transmit information - they can turn the signal up or down with the right stimulation. view more (2007-08-20)
Test allows early detection of vision problems in infants with hemangiomas of eyelids
In children with vascular birthmarks around the eye, even partial blockage of vision can lead to visual loss due to amblyopia. view more (2009-04-01)
Brain malfunction explains dehydration in elderly
As Australia faces another hot, dry summer, scientists from Melbourne's Howard Florey Institute have warned that elderly people are at risk of becoming dehydrated because their brains underestimate how much water they need to drink to rehydrate. view more (2007-12-18)
A Neural Mosaic of Tones
The brain filters what we hear. It can do this in part because particular groups of neurons react to specific frequencies of sound. view more (2006-06-23)
Using brain scans, researchers find evidence for a two-stage model of human perceptual learning
Using advanced brain imaging techniques, researchers at Georgetown University Medical Center have watched how humans use both lower and higher brain processes to learn novel tasks, an advance they say may help speed up the teaching of new skills as well as offer strategies to retrain people with perceptual deficits due to autism. view more (2007-03-15)
Penn researchers find treatment for MS also reduces vision loss in MS patients
According to a study that appears in the April 17 issue of Neurology, researchers at the University of Pennsylvania School of Medicine have found that natalizumab (TYSABRI®) - a drug that slows disability and reduces relapse rates in patients with multiple sclerosis (MS) - also reduces vision loss in patients with relapsing MS. view more (2007-04-17)
