Mobile microscopes illuminate the brain
The majority of our life is spent moving around a static world and we generate our impression of the world using visual and other senses simultaneously. view more (2009-11-03)
Future diabetes treatment may use resveratrol to target the brain
Resveratrol, a molecule found in red grapes, has been shown to improve diabetes when delivered orally to rodents. Until now, however, little has been known about how these beneficial changes are mediated in the body. view more (2009-10-06)
Blame the brain for high blood pressure
The controversial idea that one cause of high blood pressure lies within the brain, and not the heart or blood vessels, has been put forward by scientists at the University of Bristol, UK, and is published this week in the journal Hypertension. view more (2007-04-16)
Worms take the sniff test to reveal sex differences in brain
Buttery popcorn or fresh green vegetables? Your answer tells a lot about you. Now, scientists say that the way that thousands of tiny worms have answered that question likely reveals a lot about you and your brain, too. view more (2007-11-06)
New discovery about the formation of new brain cells
The generation of new nerve cells in the brain is regulated by a peptide known as C3a, which directly affects the stem cells' maturation into nerve cells and is also important for the migration of new nerve cells through the brain tissue, reveals new research from the Sahlgrenska Academy published in the journal Stem Cells. view more (2009-11-24)
New methods for brain research
Novel methods of measuring magnetic fields outside the head give further insights to the functioning of the human brain. In his doctoral thesis "Estimating Neural Currents from Neuromagnetic Measurements", Kimmo Uutela developed new methods for finding electrical activity of the brain, which enable easier identification of different... view more...

Neuronal Receptor Response May Help Explain Alzheimer's Memory Loss
Based on laboratory research, scientists at Georgetown University Medical Center have a new theory as to why people with Alzheimer's disease have trouble performing even the simplest memory tasks, such as remembering a family member's name. view more (2006-02-13)
U of Minnesota researchers discover noninvasive diagnostic tool for brain diseases
Researchers from the University of Minnesota Medical School and Brain Sciences Center at the Minneapolis VA Medical Center have identified a noninvasive and painless way to diagnose complex brain diseases. view more (2007-08-23)
Alzheimer's disease prevention may be easier than cure
Current hypotheses suggest that it is the accumulation over time of amyloid beta peptide 1-42 (Abeta42) that triggers changes in the brain that lead to cognitive dysfunction in Alzheimer's disease. view more (2005-12-09)
Do bilingual persons have distinct language areas in the brain?
A new study carried out at the University of Haifa sheds light on how first and second languages are represented in the brain of a bilingual person. view more (2009-07-08)
St. Jude scientists discover a new mechanism controlling neuronal migration
The molecular machinery that helps brain cells migrate to their correct place in the developing brain has been identified by scientists at St. Jude Children's Research Hospital. view more (2009-07-16)
MIT neuroscientists find neural stopwatch in the brain
MIT researchers have identified populations of neurons that code time with extreme precision in the primate brain. These neurons are found in two interconnected brain regions, the prefrontal cortex and the striatum, both of which are known to play critical roles in learning, movement, and thought control. view more (2009-10-20)
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)
Improved estrogen reception may sharpen fuzzy memory
Estrogen treatments may sharpen mental performance in women with certain medical conditions, but University of Florida researchers suggest that recharging a naturally occurring estrogen receptor in the brain may also clear cognitive cobwebs. view more (2008-07-30)
Children's National scientists uncover key developmental mechanisms of the amygdala
For the first time, scientists at Children's National Medical Center have successfully identified a key developmental program for the amygdala-the part of the limbic system that impacts how the brain creates emotional memories and responses. view more (2009-01-13)
Study supports theory why brain-injured children often recover
The number of sites in children's brains involved in language recognition decreases as the children age, according to a University of Cincinnati (UC) study. view more (2006-04-06)
Advances in brain imaging for epilepsy
Positron emission tomography (PET) brain scans of a brain chemical messenger system may prove sensitive enough to help plan brain surgery for epilepsy, according to a study presented at the 130th annual meeting of the American Neurological Association in San Diego. view more (2005-09-22)
Many patients who resume driving after head injury may not be fit to drive
Many patients who return to driving after traumatic brain injury report problems which can significantly affect their ability to drive, finds a study in Journal of Neurology Neurosurgery and Psychiatry. During a two and a half year period, 563 adults with traumatic brain injury were referred to one of 10 rehabilitation units in England. Patients... view more... (2001-05-30)
Cancer researchers confirm brain tumor genetic subtype informs treatment, predicts outcome
Research confirms that determining the genetic composition of brain cancers can better inform doctors and patients for treatment options and prognosis. The findings could change the future of how cancers are diagnosed. view more (2006-07-07)
Researchers discover gene mutations that cause childhood brain cancer
Researchers funded by the Canadian Cancer Society have discovered eight similar genes that, when mutated, appear to be responsible for medulloblastoma - the most common of childhood brain cancers. The findings are published today in the online edition of the journal Nature Genetics. view more (2009-03-09)
