Mandatory alcohol testing for truck and bus drivers reduces alcohol involvement in fatal crashes
Mandatory alcohol testing programs for truck and bus drivers have contributed to a significant reduction in alcohol involvement in fatal crashes, according to a new study by researchers at the Mailman School of Public Health and the Johns Hopkins Bloomberg School of Public Health. view more (2009-09-14)
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)
Women At Greater Risk Of Brain-Cell Damage From Long-Term Ecstasy Use
Authors of a Dutch study in this week's issue of THE LANCET conclude that long-term ecstasy use-especially among women-could have serious negative effects on specific cells in the brain. The study also suggests that the adverse effects of ecstasy use can sometimes be reversed among people who stop using the drug. Ecstasy is a popular recreational... view more... (2001-11-28)
Mechanism of Alzheimer's suggests combination therapy needed
Researchers at the University of Illinois at Chicago College of Medicine have discovered a mode of action for mysterious but diagnostic protein snarls found in the brains of Alzheimer's patients that suggests a one-two punch of therapy may be needed to combat the neurodegenerative disease. view more (2009-03-18)
Without glial cells, animals lose their senses
Sensory neurons have always put on a good show. But now, it turns out, they'll be sharing the credit. In groundbreaking research to appear in the October 31 issue of Science, Rockefeller University scientists show that while neurons play the lead role in detecting sensory information, a second type of cell, the glial cell, pulls the strings behind... view more...

Cell Therapy for Parkinson's Disease
According to research work at the University Hospital, cell therapy could improve many of the motor deficits of patients with Parkinson's Disease. view more (2004-05-03)
Explosion in corporate tobacco sponsorship
Corporate sponsorship by tobacco companies in the USA has rocketed, shows research in Tobacco Control. Between 1995 and 1999, tobacco company sponsorship amounted to a minimum estimated $365 million, with motor sports taking the lion's share. But tobacco dollars also funded many small, community based projects, many of them part of the public... view more... (2001-09-04)
Gradient guides nerve growth down spinal cord
The same family of chemical signals that attracts developing sensory nerves up the spinal cord toward the brain serves to repel motor nerves, sending them in the opposite direction, down the cord and away from the brain. view more (2005-08-15)
New brain cells implicated in machinery of cannabinoid signaling
The brain cells called astrocytes, and not just neurons, are sensitive to the substances called cannabinoids-the active chemicals in marijuana. view more (2008-03-27)
Research Explains How Lead Exposure Produces Learning Deficits
A study of young adult rats by researchers from the Johns Hopkins Bloomberg School of Public Health provides evidence that explains exactly how exposure to lead during brain development produces learning deficits. view more (2007-04-04)
Study offers window into human behavior, brain disease
UCSF scientists have identified a cell population that is a primary target of the degenerative brain disease known as frontotemporal dementia, which is as common as Alzheimer's disease in patients who develop dementia before age 65. view more (2006-12-26)
Pathways of emotion - from cortex to peripheral organs
Walking down a dark alley late at night is enough to give anyone the heebie-jeebies. Your heart starts racing, your palms get clammy and you get ready to run. Now researchers from Boston University have unravelled the neural pathways that transmit information about your surroundings to your organs, enabling them to respond appropriately. The... view more... (2003-10-07)
Discovery of post-stimulus activated release implies new mechanisms for dopamine release
The neurotransmitter dopamine continues to be released for nearly an hour after neurons are stimulated, suggesting the existence of secondary mechanisms that allow for sustained availability of dopamine in different regions of the brain including areas critical for memory consolidation, drug induced plasticity and maintaining active networks... view more...

Amyotrophic lateral sclerosis may involve a form of sudden, rapid aging of the immune system
Premature aging of the immune system appears to play a role in the development of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, according to research scientists from the Maxine Dunitz Neurosurgical Institute at Cedars-Sinai Medical Center, the Weizmann Institute of Science in Israel, and Sheba Medical Center in Israel. view more (2009-10-09)
Tracing the formation of long-term memory
The formation of long-term memory in fruit flies can be demonstrated by the influx of calcium into cells called mushroom body neurons that occurs after special training that includes periods of rest, said researchers from Baylor College of Medicine (BCM) in a report that appears in the current issue of the journal Neuron. view more (2006-12-07)
Prefrontal cortex loses neurons during adolescence, researchers find
Researchers at the University of Illinois have found that adolescence is a time of remodeling in the prefrontal cortex, a brain structure dedicated to higher functions such as planning and social behaviors. view more (2007-03-14)
Motor skill learning may be enhanced by mild brain stimulation
People who received a mild electrical current to a motor control area of the brain were significantly better able to learn and perform a complex motor task than those in control groups. The findings could hold promise for enhancing rehabilitation for people with traumatic brain injury, stroke and other conditions. view more (2009-01-20)
Low birth weight infants may have cognitive and physical problems when they reach adolescence
Sixteen-year-olds who weighed less than 2,000 grams (about 4.5 pounds) at birth and are not disabled are still more likely than the average teenager to have physical and mental difficulties. view more (2006-10-03)
New methods identify and manipulate 'newborn' cells in animal model of Parkinson's disease
When cells in the brain are lost through disease or injury, neighboring cells begin to divide and multiply, but only a few areas in the brain are able to produce new neurons. view more (2008-09-04)
Mayo discovers link between Huntington's and abnormal cholesterol levels in brain
Mayo Clinic researchers have discovered a protein interaction that may explain how the deadly Huntington's disease affects the brain. view more (2006-12-04)
