Working memory retains visual details despite distractions
The ability to retain memory about the details of a natural scene is unaffected by the distraction of another activity and this information is retained in "working memory". view more (2006-01-20)
Boston University psychologists find neurological mechanism for subliminal learning
Watch out - you may learn something and not even know it, says Takeo Watanabe, an associate professor of psychology at Boston University's Center for Brain and Memory. Watanabe and his team recently pinpointed the mechanism that makes subliminal learning work. Watanabe will present the team's findings at the American Psychological Society meeting... view more...

One reason to test premature babies early: Results provide clues to later cognitive development
Now a study from researchers at the Albert Einstein College of Medicine in the Bronx, N.Y., and the University of Ghent in Belgium, finds that early cognitive deficits in infancy such as poorer attention, slower processing speed and poorer recognition memory are important harbingers of later cognitive deficits. view more (2005-11-14)
Williams Syndrome, the brain and music
Children with Williams syndrome, a rare genetic disorder, just love music and will spend hours listening to or making music. Despite averaging an IQ score of 60, many possess a great memory for songs, an uncanny sense of rhythm, and the kind of auditory acuity, than can discern differences between different vacuum cleaner brands. view more (2006-10-04)
Cracking the real Da Vinci Code — what happens in the artist's brain?

Making mice with enhanced color vision
Researchers at the Johns Hopkins School of Medicine and their colleagues have found that mice simply expressing a human light receptor in addition to their own can acquire new color vision, a sign that the brain can adapt far more rapidly to new sensory information than anticipated. view more (2007-03-23)
People with Near Death Experiences Can Differ in Sleep-Wake Control
People who have had near death experiences often have different arousal systems controlling the sleep-wake states than people who have not had a near death experience. view more (2006-04-11)
Why our shifty eyes don't drive us crazy
Our eyes are constantly making saccades, or little jumps. Yet the world appears to us as a smooth whole. Somehow, the brain's visual system "knows" where the eyes are about to move and is able to adjust for that movement. view more (2006-11-09)
