Measuring brain atrophy in patients with mild cognitive impairment
Scientists at the University of California, San Diego School of Medicine have shown that a fully automated procedure called Volumetric MRI - which measures the "memory centers" of the brain and compares them to expected size - is effective in predicting the progression from mild cognitive impairment (MCI) to Alzheimer's disease. view more (2009-06-17)
Baby's first dreams
After about seven months growing in the womb, a human fetus spends most of its time asleep. Its brain cycles back and forth between the frenzied activity of rapid eye movement (REM) sleep and the quiet resting state of non-REM sleep. view more (2009-04-14)
Gene variations linked to brain aneurysms
Variations in a gene seem to be linked to brain (cerebral) aneurysms, suggests research published ahead of print in the Journal of Neurology Neurosurgery and Psychiatry. view more (2006-04-27)
Researchers identify a cell type that limits stroke damage
A research team including Serge Rivest of University Laval's Faculty of Medicine has demonstrated the existence of a type of cells that limits brain damage after a stroke. The study was recently published in the online version of Nature Medicine. view more (2009-01-28)
Virtual reality and computer technology improve stroke rehabilitation
Israeli hospitals have recently started to use virtual reality therapy for stroke patients. One commonly used program has the patient watch his virtual image on a screen. view more (2008-03-11)
New approach to detect autism earlier
A new way of understanding autistic disorders, incorporating both psychological and biological factors, could lead to the conditions being picked up earlier, research from UNSW has found. view more (2008-01-25)
Changes in brain density can help predict schizophrenia
Changes in brain density could be used to predict whether an individual who is at risk for schizophrenia is likely to develop the condition or not. view more (2006-12-07)
Preventing overload in the brain
Brain researchers in Amsterdam have observed a double control system in the hippocampus. This double control system contributes to the memory and ensures that the brain does not `crash`, as is the case during an epileptic seizure. The neurobiologists from the University of Amsterdam carried out their observations on the hippocampus of rats. The... view more... (2002-01-29)
Smell experience during critical period alters brain
Unlike the circuitry of the visual system, that of the olfactory system was thought to be hardwired: Once the neurons had formed, no amount of sensory input could change their arrangement. view more (2007-12-06)
Markers of brain cell development may help success of stem cell transplants
Four sugar-coated faces made by stem cells as they differentiate into brain cells during development have been identified by scientists. view more (2005-09-07)
UBC scientist unveils secret of newborn's first words
A new study could explain why "daddy" and "mommy" are often a baby's first words - the human brain may be hard-wired to recognize certain repetition patterns. view more (2008-08-27)
MIT study suggests caution on new anti-obesity drug in kids
Anti-obesity drugs that work by blocking brain molecules similar to those in marijuana could also interfere with neural development in young children, according to a new study from MIT's Picower Institute for Learning and Memory. view more (2008-05-08)
UC Irvine scientists unveil the 'face' of a new memory
A century-old dream of neuroscientists to visualize a memory has been fulfilled, as University of California, Irvine researchers, using newly developing microscopic techniques, have captured first-time images of the changes in brain cell connections following a common form of learning. view more (2007-07-25)
Moderate alcohol consumption enhances the formation of new nerve cells - may contribute to alcohol dependency
Moderate alcohol consumption over a relatively long period of time can enhance the formation of new nerve cells in the adult brain. The new cells could prove important in the development of alcohol dependency and other long-term effects of alcohol on the brain. The findings are published by Karolinska Institutet. view more (2005-04-26)
Estrogen can reduce stroke damage by inactivating protein
Estrogen can halt stroke damage by inactivating a tumor-suppressing protein known to prevent many cancers, Medical College of Georgia researchers say. view more (2009-07-17)
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)
New research identifies gene important for nicotine's effects on the brain
New research identifies an important gene that influences several aspects of nicotine-induced behaviors in the brain. The study, funded by National Institutes of Drug Abuse, was presented today at the American College of Neuropsychopharmacology's Annual Meeting. view more (2006-12-06)
Neuroscientists discover long-term potentiation in the olfactory bulb
Ben W. Strowbridge, Ph.D, associate professor of Neuroscience and Physiology/Biophysics, and Yuan Gao, a Ph.D. student in the neurosciences program at Case Western Reserve University School of Medicine, are the first to discover a form of synaptic memory in the olfactory bulb, the part of the brain that processes the sense of smell. view more (2009-05-04)
Memory mission explores new territory in neuroscience
Astrophysicists peer into the far corners of deep space for dark matter, but for neuroscientists at the Queensland Brain Institute (QBI) exploring the unknown is much closer to home. view more (2008-11-21)
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)
