Growth factor stimulates rapid extension of key motor neurons in brain
A growth factor known to be important for the survival of many types of cells stimulates rapid extension of corticospinal motor neurons - critical brain cells that connect the cerebral cortex with the spinal cord and that die in motor neuron diseases like amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease). view more (2006-11-06)
Dying of excitement
For neurons, overexcitement is deadly. To avoid this, brain cells must sop up unneeded neurotransmitters from the synapse through membrane-bound transporters. If these transporters fail, neurons and other brain cells get excited to death- a phenomenon that may contribute to brain damage during stroke and Alzheimer's disease. view more (2006-03-06)
Mathematical analysis techniques for the study of epilepsy
Dr. Elena Urrestarazu has employed a mathematical technique, known as Independent Components Analysis, in order to separate brain activities of different origins. In her PhD, defended at the Faculty of Medicine of the University of Navarre, Dr. Urrestarazu demonstrated that this technique could be applied brain registers in humans. view more (2004-11-12)
Role of noise in neurons
Addressing a current issue in neuroscience, Aldo Faisal and Simon Laughlin from Cambridge University investigate the reliability of thin axons for transmitting information. They show that noise effects in ion channels in the brain are much larger than previously assumed - meaning the fidelity of transmission is compromised. view more (2007-05-04)
Newly discovered gene may hold clues to evolution of human brain capacity
Scientists have discovered a gene that has undergone accelerated evolutionary change in humans and is active during a critical stage in brain development. view more (2006-08-17)
Blocking immune cell action increases Alzheimer's-associated protein deposits
The immune system's response against amyloid-beta, the protein that forms plaques in the brains of patients with Alzheimer's disease, appears to protect the brain from damage in early stages of the devastating neurological disorder. view more (2007-03-28)
Study finds B-vitamin deficiency may cause vascular cognitive impairment
A deficiency of B-vitamins may cause vascular cognitive impairment, according to a new study. Researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University used an experimental model to examine the metabolic, cognitive, and microvascular effects of dietary B-vitamin deficiency. view more (2008-09-02)
Low cholesterol cues cataract development
Cataracts are a leading cause of blindness worldwide. Using a rat model of cataract formation, Masayuki Mori and researchers at Shinshu University Graduate School of Medicine in Japan have now found a link between cataracts and cholesterol. view more (2006-01-27)
Memory uses separate information pathways
The researchers studied two signals from different sensory parts of the brain, one of which arrived at the perirhinal and the other at the postrhinal cerebral cortex. These parts of the brain are located close to the sulcus and receive information from areas of the brain which process different types of sensory information. The information enters... view more...

Deep sleep short-circuits brain's grid of connectivity
In the human brain, cells talk to one another through the routine exchange of electrical signals. But when people fall into a deep sleep, the higher regions of the brain-regions that during waking hours are a bustling grid of neural dialogue-apparently lose their ability to communicate effectively, causing consciousness to fade. view more (2005-09-30)
Brain malformations significantly associated with preterm birth, Wake Forest research shows
New research out of Wake Forest University School of Medicine provides for the first time a solid scientific answer for the long-standing question of whether there is an association between preterm birth and brain malformations. view more (2009-07-06)
Routine Testing After Aneurysm Coiling Carries Low Risk
A very low risk of complication is associated with a routine test that determines whether a brain aneurysm treated with endovascular coiling has started to recur, a study led by the University of Cincinnati Neuroscience Institute has shown. view more (2008-11-19)
UNC, Duke lead first statewide shaken baby prevention research project in US
Child abuse prevention experts from the University of North Carolina at Chapel Hill Injury Prevention Research Center and School of Medicine and Duke University Medical Center will undertake a $7 million statewide shaken baby prevention project. view more (2008-01-17)
PET's Molecular Imaging Power May Be Best Indicator for Determining Which Patients Develop Alzheimer's
Positron emission tomography (PET) imaging-with the radiotracer fluorodeoxyglucose (FDG)-is a promising tool in detecting Alzheimer's disease in patients who have mild cognitive impairment (MCI). view more (2005-10-06)
Carnegie Mellon researchers discover key deficiencies in brains of people with autism
In a pair of groundbreaking studies, brain scientists at Carnegie Mellon University and the University of Pittsburgh have discovered that the anatomical differences that characterize the brains of people with autism are related to the way those brains process information. view more (2006-07-13)
Rare cell prevents rampant brain activity
One of the mysteries of the brain is how it avoids ending up in a state of chaos, something which happens only on exceptional occasions, when it can lead to epileptic fits. Scientists at Karolinska Institutet have now uncovered a new mechanism controlling how the brain keeps its neuronal activity in check. view more (2007-03-05)
Commonly used drug offers promise for premature babies
Scientists have found evidence that the cox-2 inhibitor celecoxib, a common pain reliever used to treat arthritis, may offer a new way to reduce the risk of the most common cause of brain damage in babies born prematurely. view more (2007-05-18)

Groundbreaking study helps explain why preemie brains improve over time
Infants born prematurely and with hypoxia-inadequate oxygen to the blood-are able to recover some cells, volume and weight in the brain after oxygen supply is restored, Yale School of Medicine researchers report in Experimental Neurology. view more (2005-06-28)
St. Joseph's Hospital in Phoenix offers special test for children with stroke risk
Children's Rehabilitative Services (CRS) at St. Joseph's Children's Health Center in Phoenix is using a special ultrasound to identify the risk for stroke in children who have sickle cell disease. view more (2006-01-31)
