Pathways of emotion - from cortex to peripheral organs
Walking down a dark alley late at night is enough to give anyone the heebie-jeebies. Your heart starts racing, your palms get clammy and you get ready to run. Now researchers from Boston University have unravelled the neural pathways that transmit information about your surroundings to your organs, enabling them to respond appropriately. The... view more... (2003-10-07)
Research Shows How Visual Stimulation Turns Up Genes to Shape the Brain
Scientists have long known that brains need neural activity to mature and that sensory input is most important during a specific window of time called the "critical period" when the brain is primed for aggressive learning. view more (2006-05-08)
Age-related difficulty recognizing words predicted by brain differences
Older adults may have difficulty understanding speech because of age-related changes in brain tissue, according to new research in the May 13 issue of The Journal of Neuroscience. view more (2009-05-13)
MIT neuroscientists find neural stopwatch in the brain
MIT researchers have identified populations of neurons that code time with extreme precision in the primate brain. These neurons are found in two interconnected brain regions, the prefrontal cortex and the striatum, both of which are known to play critical roles in learning, movement, and thought control. view more (2009-10-20)
Impaired vision common in US
A new report estimates that approximately 14 million people aged 12 years and older in the U.S. have vision impairment, of which more than 80 percent could be improved with the use of corrective lenses. view more (2006-05-10)
Subliminal advertising leaves its mark on the brain
UCL (University College London) researchers have found the first physiological evidence that invisible subliminal images do attract the brain's attention on a subconscious level. view more (2007-03-09)
New Study Indicates Radiologists Need Standards to Ensure Optimal Visual Accuracy
Radiologists, like professional pilots for example, depend on good vision as part of their occupation. However, radiologists unlike pilots are not required to undergo regular vision testing. view more (2009-06-10)
Study reveals we seek new targets during visual search, not during other visual behaviors
When we look at a scene in front of us, we need to focus on the important items and be able to ignore distracting elements. Studies have suggested that inhibition of return (in which our attention is less likely to return to objects we've already viewed) helps make visual search more efficient - when searching a scene to find an object, we have a... view more...

Failure to suppress irrelevant brain activity in Alzheimer disease
A study by Alexander Drzezga and colleagues (of the Technical University Munich, Germany) to be published in the international open access journal PLoS Medicine now shows that this focusing process is defective in people with Alzheimer disease (AD). view more (2005-09-20)
Visual impairment associated with increased mortality risk
Individuals age 49 and older with cataract and those age 49 to 74 years with age-related macular degeneration appear to have higher mortality rates over an 11-year period than those without such visual impairments. view more (2007-07-10)
Erotic images prove useful in coaxing out unconscious brain activity
When your eyes are presented with erotic images in a way that keeps you from becoming aware of them, your brain can still detect and respond to the images according to your gender and sexual orientation. view more (2006-10-27)
Researchers find an evolutionarily preserved signature in the primate brain
Researchers have determined that there are hundreds of biological differences between the sexes when it comes to gene expression in the cerebral cortex of humans and other primates. view more (2008-06-20)
Sticks and Stones: A New Study on Social and Physical Pain
We all know the famous saying: "Sticks and stones may break my bones, but words will never hurt me," but is this proverb actually true? view more (2008-08-28)
Scientists identify brain regions that decide where we look
Scientists have found the brain regions that decide where we look, and where to direct our eyes when we're faced with a difficult choice, such as looking someone straight in the eye or looking away. view more (2005-01-24)
Hard-wiring the fruit fly's visual system
Both vertebrate and fruit fly have so-called visual maps in the brain that represent the world they see. view more (2006-09-21)
Read My Lips: Using Multiple Senses in Speech Perception
When someone speaks to you, do you see what they are saying? We tend to think of speech as being something we hear, but recent studies suggest that we use a variety of senses for speech perception - that the brain treats speech as something we hear, see and even feel. view more (2009-02-12)
Vision loss more common in people with diabetes
Visual impairment appears to be more common in people with diabetes than in those without the disease, according to a report in the October issue of Archives of Ophthalmology, one of the JAMA/Archives journals. view more (2008-10-14)
Scientists uncover why picture perception works
A team of scientists has solved a key mystery of visual perception. Why do pictures look the same when viewed from different angles? view more (2005-09-22)
Emotional memories can be suppressed with practice, new CU-Boulder study says
A new University of Colorado at Boulder study shows people have the ability to suppress emotional memories with practice, which has implications for those suffering from conditions ranging from post-traumatic stress disorder to depression. view more (2007-07-13)
New study shows those blinded by brain injury may still 'see'
Except in clumsy moments, we rarely knock over the box of cereal or glass of orange juice as we reach for our morning cup of coffee. New research at The University of Western Ontario has helped unlock the mystery of how our brain allows us to avoid these undesired objects. view more (2009-09-03)
