Lost in thought: Brain research
Can one literally "lose oneself" in an experience? Many theoretical models of the mind reject this notion, proposing that awareness is dependent on the mediation of areas involved in self representation - a vigilant, self-aware "observer" network - in the human brain. view more (2006-05-17)
Preclinical work shows how one gene causes severe mental retardation
Researchers at Duke University Medical Center and the University of North Carolina have discovered in mice how a single disrupted gene can cause a form of severe mental retardation known as Angelman syndrome. view more (2009-05-11)
Songbirds offer clues to highly practiced motor skills in humans
The melodious sound of a songbird may appear effortless, but his elocutions are actually the result of rigorous training undergone in youth and maintained throughout adulthood. His tune has virtually "crystallized" by maturity. view more (2007-12-27)
Memory uses separate information pathways
The researchers studied two signals from different sensory parts of the brain, one of which arrived at the perirhinal and the other at the postrhinal cerebral cortex. These parts of the brain are located close to the sulcus and receive information from areas of the brain which process different types of sensory information. The information enters... view more...

Brain's problem-solving function at work when we daydream
A new University of British Columbia study finds that our brains are much more active when we daydream than previously thought. view more (2009-05-12)
Clues to the progression of Alzheimer's disease revealed in brain imaging studies
A novel imaging agent heralded for its potential to diagnose Alzheimer's disease during life is now giving researchers information never before available about how and where the disease progresses in the brain. view more (2005-11-15)
Potential new approach to treat cognitive impairments in schizophrenia
A new study reports important evidence for a potential new treatment approach for those diagnosed with schizophrenia. Schizophrenia is considered one of the most devastating of the major psychiatric disorders, which has three distinct facets, often referred to as "positive" (hallucinations, delusions), "negative" (blunted... view more...

Brain's 'hate circuit' identified
People who view pictures of someone they hate display activity in distinct areas of the brain that, together, may be thought of as a 'hate circuit', according to new research by scientists at UCL (University College London). view more (2008-10-29)
Ultrasound affects embryonic mouse brain development
The prolonged and frequent use of ultrasound on pregnant mice causes brain abnormalities in the developing mouse fetus. view more (2006-08-08)
Brain waves show sound processing abnormalities in autistic children
Abnormalities in auditory and language processing may be evaluated in children with autism spectrum disorder by using magnetoencephalography (MEG), according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). view more (2008-12-01)
Sooner is better with cochlear implants, Stanford scientist shows
Cochlear implants allow the deaf to hear. Their brains learn to understand the artificial electrical stimulation that the implants provide to the cochlea as sound. view more (2005-12-06)
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)
New tool to assess speech development in infants, toddlers with hearing impairments
The number of hearing impaired infants and toddlers who are successfully aided by technological devices, such as hearing aids and cochlear implants, continues to grow, but there are still unknowns about these children's speaking abilities, according to a Purdue University expert. view more (2008-09-24)
Brain imaging reveals breakdown of normal emotional processing
Brain imaging has revealed a breakdown in normal patterns of emotional processing that impairs the ability of people with clinical depression to suppress negative emotional states. view more (2007-08-17)
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)
Groundbreaking study helps explain why preemie brains improve over time
Infants born prematurely and with hypoxia-inadequate oxygen to the blood-are able to recover some cells, volume and weight in the brain after oxygen supply is restored, Yale School of Medicine researchers report in Experimental Neurology. view more (2005-06-28)
Social interactions can alter gene expression in the brain, and vice versa
Our DNA determines a lot about who we are and how we play with others, but recent studies of social animals (birds and bees, among others) show that the interaction between genes and behavior is more of a two-way street than most of us realize. view more (2008-11-07)
EEGs show brain differences between poor and rich kids
University of California, Berkeley, researchers have shown for the first time that the brains of low-income children function differently from the brains of high-income kids. view more (2008-12-03)
Neuroscientists searching for roots of empathy
In a pair of pioneering studies, a French (INSERM) and American team of social-cognitive neuroscientists have identified a network of brain regions that are involved in human imitation and specific brain areas that enable a person to distinguish the self from others. The research is part of a larger effort to find the neurological basis of social... view more... (2002-01-23)
Monkey brains signal the desire to explore
Sticking with what you know often comes at the price of learning about more favorable alternatives. view more (2009-09-08)
