PHILADELPHIA - Neurosurgeons can visualize important pathways in the brain using an imaging technique called diffusion tensor imaging (DTI), to better adapt brain tumor surgeries and preserve language, visual and motor function while removing cancerous tissue.

Amsterdam, NL, April 1, 2013 – In a mouse model of early Parkinson's disease (PD), animals displayed movement deficits, loss of tyrosine-hydroxylase (TH)-positive fibers in the striatum, and astro-gliosis and micro-gliosis in the substantia nigra (SN), without the loss of nigral dopaminergic neurons. These findings, which may cast light on the molecular processes involved in the initial stages of PD, are available in the current issue of Restorative Neurology and Neuroscience.
DETROIT – In a first-of-its-kind experiment using microvesicles generated from mesenchymal bone marrow cells (MSCs) to treat cancer, neurological researchers at Henry Ford Hospital have discovered a novel approach for treatment of tumor.Specifically, the research team found that introducing genetic material produced by MSCs, significantly reduced a particularly resistant form of malignant brain tumor in living lab rats.
It is known that family-based treatment that combines nutrition and exercise education, along with behavior modification, is a good approach to help children lose weight. But clinic-based weight-control programs for childhood obesity are not accessible to many families, due to issues such as cost or time commitment.
Johns Hopkins scientists say they have evidence from animal studies that a type of central nervous system cell other than motor neurons plays a fundamental role in the development of amyotrophic lateral sclerosis (ALS), a fatal degenerative disease. The discovery holds promise, they say, for identifying new targets for interrupting the disease's progress.
DARIEN, IL – A new study found that obstructive sleep apnea, a common form of sleep-disordered breathing (SDB), is associated with increased rates of ADHD-like behavioral problems in children as well as other adaptive and learning problems.
EAST LANSING, Mich. — Students perform better when their instructors use hand gestures – a simple teaching tool that could yield benefits in higher-level math such as algebra.
A study published in Child Development, the top-ranked educational psychology journal, provides some of the strongest evidence yet that gesturing may have a unique effect on learning. Teachers in the United States tend to use gestures less than teachers in other countries.
Los Angeles, CA (March 28, 2013) While compared to men, women continue to be underrepresented in math and science courses and careers, is this disparity a true reflection of male and female student ability? According to a study to be released tomorrow in Psychology of Women Quarterly, a SAGE journal, male and female students earn similar grades in math and science while Asian American students of both genders outperform all other races.
TORONTO, March 28, 2013—Ice hockey accounts for nearly half of all traumatic brain injuries among children and youth participating in organized sports who required a trip to an emergency department in Canada, according to a new study out of St. Michael's Hospital.
The results are part of a first-of-its-kind study led by Dr. Michael Cusimano that looked at causes of sports-related brain injuries in Canadian youth and also uncovered some prevention tactics that could be immediately implemented to make sports safer for kids.
Eating more fiber may decrease your risk of first-time stroke, according to new research in the American Heart Association journal Stroke.
Dietary fiber is the part of the plant that the body doesn't absorb during digestion. Fiber can be soluble, which means it dissolves in water, or insoluble.
Previous research has shown that dietary fiber may help reduce risk factors for stroke, including high blood pressure and high blood levels of low-density lipoprotein (LDL) "bad" cholesterol.
Focusing on the present rather than letting the mind drift may help to lower levels of the stress hormone cortisol, suggests new research from the Shamatha Project at the University of California, Davis.
The ability to focus mental resources on immediate experience is an aspect of mindfulness, which can be improved by meditation training.
People could learn a lot from vervet monkeys. When vervets need to work together, they don't tell each other what to do or punish uncooperative behavior. But according to evidence reported on March 28 in the Cell Press journal Current Biology, they do get by, with a little patience.
"The vervets show us that tolerance towards group members and patience while others are learning how they can improve things individually can go a long way in solving coordination problems," said Ronald Noë of Université de Strasbourg in France.
A study led by Zachary Mainen, Director of the Champalimaud Neuroscience Programme, and published today (March 28th) in the scientific journal, Neuron, reports that when rats were challenged with a series of perceptual decision problems, their performance was just as good when they decided rapidly as when they took a much longer time to respond. Despite being encouraged to slow down and try harder, the subjects of this study achieved their maximum performance in less than 300 milliseconds.
In 2010, almost 2 million American children had at least one parent in active military duty. A new University of Iowa study suggests that deployment of a parent puts these children at an increased risk for drinking alcohol and using drugs.
Considerable opportunity exists to improve interventions and outcomes of traumatic brain injury (TBI) in older adults, according to three studies published in the recent online issue of NeuroRehabilitation by researchers from the Icahn School of Medicine at Mount Sinai.
