Alcoholics' deficits in smell are linked to frontal lobe dysfunction
Prior research has shown that chronic alcoholism is associated with numerous olfactory deficits in odor judgment, odor identification, odor sensitivity, and the ability to qualitatively discriminate between odors. New findings indicate that olfactory deficits among alcoholics are associated with prefrontal cognitive dysfunction, specifically,... view more... (2006-07-25)
Why delaying gratification is smart: A neural link between intelligence and self-control
If you had a choice between receiving $1,000 right now or $4,000 ten years from now, which would you pick? Psychologists use the term "delay discounting" to describe our inability to resist the temptation of a smaller immediate reward in lieu of receiving a larger reward at a later date. view more (2008-09-10)
Delusions associated with consistent pattern of brain injury
A new study provides a novel theory for how delusions arise and why they persist. NYU Langone Medical Center researcher Orrin Devinsky, MD, performed an in-depth analysis of patients with certain delusions and brain disorders revealing a consistent pattern of injury to the frontal lobe and right hemisphere of the human brain. view more (2009-01-14)
Adult brain can change, study confirms
It is well established that a child's brain has a remarkable capacity for change, but controversy continues about the extent to which such plasticity exists in the adult human primary sensory cortex. view more (2007-09-06)
Healthy older brains not significantly smaller than younger brains, new imaging study shows
The belief that healthy older brains are substantially smaller than younger brains may stem from studies that did not screen out people whose undetected, slowly developing brain disease was killing off cells in key areas, according to new research. As a result, previous findings may have overestimated atrophy and underestimated normal size for the... view more... (2009-09-08)
Neural bottleneck found that thwarts multi-tasking
Many people think they can safely drive while talking on their cell phones. Vanderbilt neuroscientists Paul E. Dux and René Marois have found that when it comes to handling two things at once, your brain, while fast, isn't that fast. view more (2007-01-19)
Improving quality of life for brain tumour patients
A new neuroimaging study at the Montreal Neurological Institute and Hospital at McGill University aims to ensure the highest quality of life for patients by assessing their cognitive skills before, during, and after brain tumour surgery. view more (2008-04-22)
Memory loss in older adults due to distractions, not inability to focus
The short-term memory problems that accompany normal aging are associated with an inability to filter out surrounding distractions, not problems with focusing attention, according to a study by researchers at the University of California, Berkeley. view more (2005-09-12)
Having right timing 'connections' in brain is key to overcoming dyslexia
Using new software developed to investigate how the brains of dyslexic children are organized, University of Washington researchers have found that key areas for language and working memory involved in reading are connected differently in dyslexics than in children who are good readers and spellers. view more (2007-09-05)
Scientists identify brain circuits used in sensation of touch
The ability to tactually recognize fine spatial details, such as the raised dots used in braille, is especially important to those who are blind. view more (2007-10-11)
A direct gaze enhances face perception
Gaze direction is significant for the processing of visual information from the human face. Researchers in an Academy of Finland funded research project have discovered that the visual system of the brain processes another person's face more efficiently when the person's gaze is straight ahead than when the gaze is averted. view more (2008-08-14)
Chilean authors, publishing in Science, discover drug-craving brain region in rats
Chilean researchers have identified a region of the brain - the insular cortex - that plays a role in drug craving in amphetamine-addicted rats, according to a report published in the 26 October issue of the journal Science, published by the American Association for the Advancement of Science (AAAS), the nonprofit science society. view more (2007-10-26)
Scientists adapt economics theory to trace brain's information flow
Scientists have used a technique originally developed for economic study to become the first to overcome a significant challenge in brain research: determining the flow of information from one part of the brain to another. view more (2008-10-10)
Scientists learn how the brain 'boots up' to process information from the senses
The same chemical in the body that is targeted by the drug Viagra® also helps our brains "boot up" in the morning so we can process sights, sound, touch and other sensory information. view more (2006-08-10)
Meditation associated with increased grey matter in the brain
Meditation is known to alter resting brain patterns, suggesting long lasting brain changes. view more (2005-11-14)
Simple brain mechanisms explain arbitrary human visual decisions
Mark Twain, a skeptic of the idea of free will, argues in his essay "What Is Man?" that humans do not command their minds or the opinions they form. view more (2008-11-10)
Color contrast is 'seen' by the brain early doors
Colour contrast is detected much earlier in the brain than previously thought, a new study shows. view more (2007-09-10)
German high-school students involved in an astronomical research project
This week, Astronomy & Astrophysics publishes a somewhat unusual research article because it is co-authored by German high-school students. view more (2009-11-06)
Risk and reward compete in brain
That familiar pull between the promise of victory and the dread of defeat - whether in money, love or sport - is rooted in the brain's architecture, according to a new imaging study. view more (2008-10-10)
Brain activity linked to the parental instinct
Why do we almost instinctively treat babies as special, protecting them and enabling them to survive" Darwin originally pointed out that there is something about infants which prompts adults to respond to and care for them which allows our species to survive. view more (2008-02-27)
