Losing sleep undoes the rejuvenating effects new learning has on the brain
Sleep deprivation impairs spatial learning - including remembering how to get to a new destination. And now scientists are beginning to understand how that happens view more (2006-01-09)
Violent video games leave teenagers emotionally aroused
A new study has found that adolescents who play violent video games may exhibit lingering effects on brain function, including increased activity in the region of the brain that governs emotional arousal and decreased activity in the brain's executive function, which is associated with control, focus and concentration. view more (2006-11-29)
Personality predictors of intelligence change from younger to older adulthood
An ability to be open to new situations may predict intelligence earlier in life, says a new study, but disagreeableness may predict intelligence later in life. view more (2006-08-11)
Study shows link between morbid obesity, low IQ in toddlers
University of Florida researchers have discovered a link between morbid obesity in toddlers and lower IQ scores, cognitive delays and brain lesions similar to those seen in Alzheimer's disease patients, a new study shows. view more (2006-09-01)
Alzheimer's disease progresses more rapidly in highly educated people
High levels of education may help ward off Alzheimer's disease, but they also speed up its progression once developed, reveals research in the Journal of Neurology Neurosurgery and Psychiatry. view more (2006-02-16)
Boosting brain power — with chocolate
Eating chocolate could help to sharpen up the mind and give a short-term boost to cognitive skills, a University of Nottingham expert has found. view more (2007-02-21)
Daytime light exposure dynamically enhances brain responses
Exposure to light is known to enhance both alertness and performance in humans, but little is understood regarding the neurological basis for these effects, especially those associated with daytime light exposure. view more (2006-08-22)
Chronic drinking and smoking cause both separate and interactive brain injury
Most alcoholics in North America are chronic smokers. While much is known about the adverse effects of chronic smoking on cardiac, pulmonary and vascular function as well as the risk for various cancers, little is known about its effects on brain neurobiology and function. view more (2006-01-25)
TV has negative impact on very young children's learning abilities
Television viewing before the age of three may have adverse effects on subsequent cognitive development, according to a study in the July issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals. view more (2005-07-05)
Researchers isolate causes of cognitive loss following coronary artery bypass surgery
Minimizing trauma to the body's largest artery - the aorta - during heart bypass surgery can significantly reduce cognitive loss that often follows the operation. view more (2006-01-23)
Brain function in schizophrenia can improve with support, holds promise for cognitive rehabilitation
When encouraged to use memorization strategies commonly employed by healthy individuals, people with schizophrenia can be helped to remember information just as well as their healthy counterparts, a process that in itself seems to spur a normalization of memory-related activities in the brains of people with schizophrenia. view more (2005-07-06)
Alzheimer's pathology related to episodic memory in those without dementia
Alzheimer's pathology can appear in the brains of older men and women without dementia or mild cognitive impairment. view more (2006-06-27)
Study shows fruit and vegetable juice consumption may reduce risk of Alzheimer's disease
Drinking fruit and vegetable juices frequently may delay the onset of Alzheimer's disease. view more (2006-09-01)
Does smoking cloud the brain?
Smokers often say that smoking a cigarette helps them concentrate and feel more alert. But years of tobacco use may have the opposite effect, dimming the speed and accuracy of a person's thinking ability and bringing down their IQ, according to a new study led by University of Michigan researchers. view more (2005-10-11)
Human brains pay a price for being big
Metabolic changes responsible for the evolution of our unique cognitive abilities indicate that the brain may have been pushed to the limit of its capabilities. Research published today in BioMed Central's open access journal Genome Biology adds weight to the theory that schizophrenia is a costly by-product of human brain evolution. view more (2008-08-05)
New study finds that older Americans may improve memory by exercising their brains and bodies
New research released today at the American College of Neuropsychopharmacology's Annual Meeting found that older Americans may improve their memory by making simple lifestyle changes - including memory exercises, physical fitness, healthy eating and stress reduction. view more (2005-12-13)
Patients regain cognitive function after radiation for brain tumors
Patients who suffer from low-grade brain tumors are able to regain normal cognitive function after receiving radiation therapy to shrink their tumor. view more (2005-11-16)
Baby got math
Cognitive neuroscientists have shown that babies have an abstract numerical sense, as demonstrated by their ability to match the number of voices they hear to the number of faces they expect to see. view more (2006-02-14)
Accelerated evolution converts RNA enzyme to DNA enzyme in vitro
This 'evolutionary conversion' provides a modern-day snapshot of how life as we understand it may have first evolved out of the earliest primordial mix of RNA-like molecules-sometimes referred to as the "pre-RNA world"-into a more complex form of RNA-based life (or the "RNA world") and eventually to cellular life based on DNA... view more...

Nicotine exposure during development leads to hearing problems
Scientists know that children of women who smoke during pregnancy can develop hearing-related cognitive deficits. For the first time, researchers believe they have evidence that not only implicates nicotine as the culprit, but also shows what the substance does to the brain to cause these deficits. view more (2006-07-19)
