Large DNA stretches, not single genes, shut off as cells mature
Experiments at Johns Hopkins have found that the gradual maturing of embryonic cells into cells as varied as brain, liver and immune system cells is apparently due to the shut off of several genes at once rather than in individual smatterings as previous studies have implied. view more (2009-01-20)
PET imaging focuses on medication's purported ability to improve mental performance
Concerned by the growing numbers of people using stimulant medications such as methylphenidate (MP)-either legally or illegally-to improve attention and focus, researchers used positron emission tomography (PET) imaging with the radiotracer fluorodeoxyglucose (FDG) to assess the effects of the drug on brain function in the normal human brain. view more (2008-06-17)
Functional MRI enables noninvasive evaluation of epilepsy patients
Functional magnetic resonance imaging (fMRI) of the brain reduces the need for invasive testing of seizure disorder patients being considered for surgical treatment, according to a study published in the July issue of the journal Radiology. view more (2005-06-28)
Imaging shows structural changes in mild traumatic brain injury
Researchers report that diffusion tensor imaging can identify structural changes in the white matter of the brain that correlates to cognitive deficits even in patients with mild traumatic brain injury. view more (2007-10-26)
Exercise helps sustain mental activity as we age, may prevent dementia-like illnesses
Based on a review of studies on exercise and its effect on brain functioning in human and animal populations, researchers find that physical exercise may slow aging's effects and help people maintain cognitive abilities well into older age. view more (2006-08-14)
First-time Internet users find boost in brain function after just 1 week
You can teach an old dog new tricks, say UCLA scientists who found that middle-aged and older adults with little Internet experience were able to trigger key centers in the brain that control decision-making and complex reasoning after just one week of surfing the Web. view more (2009-10-20)
Alzheimer's gene raises newborns' cerebral palsy risk
Apolipoprotein E (APOE), a gene associated with heightened risk for Alzheimer's disease in adults, can also increase the likelihood that brain-injured newborns will develop cerebral palsy, researchers at Children's Memorial Research Center have discovered. view more (2007-02-05)
How Rett Syndrome mutation targets the brain
Researchers have pinpointed why mutations that cause Rett Syndrome (RTT)-among the leading causes of mental retardation in females-specifically target the brain rather than other body tissues. view more (2006-10-19)
Linking 2 molecular pieces of the Alzheimer's puzzle
Researchers have uncovered a biological link between the protein whose mutation causes early-onset Alzheimer's disease (AD) and a gene variant linked to late-onset AD. The researchers said their finding could lead to new approaches to treating AD. view more (2007-10-04)
In the loop: Scientists reveal how signals travel through rat's whiskers
Like blind peoples' fingers, rats use their whiskers to engage in active sensing - a combination of movement and touch - when trying to figure out the location and identity of a certain object. view more (2006-05-17)
McMaster University researchers discover zip codes for protein
McMaster scientists are very close to defining small molecule drugs that should be able to redirect the huntingtin protein from accumulating in the wrong place within brain cells, which could potentially translate to a therapy for Huntington's Disease (HD). view more (2007-01-30)
Polluted prey causes wild birds to change their tune
Considerable attention has been paid to the effects of endocrine disrupting chemicals in aquatic environments, but rather less attention has been given to routes of contamination on land. view more (2008-02-27)
Smoking seems to increase brain damage in alcoholics
It is already well-known that the brains of long-term alcoholics atrophy and shrink, the study authors say, but the new findings are the first evidence that cigarette smoking might contribute to that atrophy, particularly in grey matter of the parietal and temporal lobes. view more (2005-09-29)
Aging brain reduces ovulation
Dutch researcher Annelieke Franke has discovered that the aging of the brain adversely affects the fertility of female rats. The scientist suspects that her research will provide insights into fertility problems of women over the age of 30. Franke studied relatively young subfertile rats. Although the pituitary gland and ovaries of these rats... view more... (2003-10-10)
Brain structure provides key to unraveling function of bizarre dinosaur crests
Paleontologists have long debated the function of the strange, bony crests on the heads of the duck-billed dinosaurs known as lambeosaurs. The structures contain incredibly long, convoluted nasal passages that loop up over the tops of their skulls. view more (2008-10-16)
Complexity constrains evolution of human brain genes
Despite the explosive growth in size and complexity of the human brain, the pace of evolutionary change among the thousands of genes expressed in brain tissue has actually slowed since the split, millions of years ago, between human and chimpanzee. view more (2006-12-26)
Carnegie Mellon neuroscientist proposes new theory of brain flexibility
Carnegie Mellon University neuroscientist Marcel Just and Stanford postdoctoral fellow Sashank Varma have put forward a new computational theory of brain function that provides answers to one of the central questions of modern science: How does the human brain organize itself to give rise to complex cognitive tasks such as reading, problem solving... view more...

Heart failure treated 'in the brain'
Beta-blockers heal the heart via the brain when administered during heart failure, according to a new study by UCL (University College London). view more (2008-03-26)
Brain implants may help stroke patients overcome partial paralysis
Scientists have shown for the first time that neuroprosthetic brain implants may be able to help stroke patients with partial paralysis. view more (2008-11-12)
Computer obeys thoughts via Brain-Computer Interface
A research group led by Academy Professor Mikko Sams is developing a brain-computer interface, a device that transforms electrical or magnetic brain signals into commands a computer can understand. Equipment of this kind is necessary. For instance, it enables physically disabled persons to use a computer keyboard. The Brain-Computer Interface, or... view more... (2005-03-02)
