Even when its clot-dissolving powers are removed, the stroke drug tPA can still protect brain cells from the loss of oxygen and glucose induced by a stroke, researchers have discovered.

The finding suggests that a modified version of tPA could provide benefits to patients who have experienced a stroke, without increasing the risk of bleeding.

The results will be published in the Journal of Neuroscience.

LOS ANGELES — A team led by a physician-scientist at the University of Southern California (USC) has created an experimental drug that reduces brain damage and improves motor skills among stroke-afflicted rodents when given with federally approved clot-busting therapy.

Clinical trials to test the safety of the drug in people are expected to start later this summer.

AURORA, Colo. (July 17, 2012) –Researchers at the University of Colorado School of Medicine have found a drug that boosts memory function in those with Down syndrome, a major milestone in the treatment of this genetic disorder that could significantly improve quality of life.

Markow worked with individuals with SCI who had limited feeling or movement in their hands. Each suffered a spinal injury more than a year prior to the study. The eight-week project required study participants to practice playing the piano for 30 minutes, three times a week. Half used the MMT glove to practice; half did not.

The ability of infants to recognize speech is more sophisticated than previously known, researchers in New York University's Department of Psychology have found. Their study, which appears in the journal Developmental Psychology, showed that infants, as early as nine months old, could make distinctions between speech and non-speech sounds in both humans and animals.

You're headed out the door and you realize you don't have your car keys. After a few minutes of rifling through pockets, checking the seat cushions and scanning the coffee table, you find the familiar key ring and off you go. Easy enough, right? What you might not know is that the task that took you a couple seconds to complete is a task that computers –– despite decades of advancement and intricate calculations –– still can't perform as efficiently as humans: the visual search.

Johns Hopkins researchers say they have discovered a cause-and-effect relationship between two well-established biological risk factors for schizophrenia previously believed to be independent of one another.

The findings could eventually lead researchers to develop better drugs to treat the cognitive dysfunction associated with schizophrenia and possibly other mental illnesses.

OAK BROOK, Ill. – A buildup of sodium in the brain detected by magnetic resonance imaging (MRI) may be a biomarker for the degeneration of nerve cells that occurs in patients with multiple sclerosis (MS), according to a new study published online in the journal Radiology.

July 16, 2012 – (BRONX, NY) – Researchers at Albert Einstein College of Medicine of Yeshiva University and Montefiore Medical Center have found that people with a form of mild cognitive impairment (MCI), a risk factor for developing Alzheimer's disease, have twice the risk of dying compared with cognitively normal people. Those with dementia have three times the risk. The findings are being presented at the Alzheimer's Association International Conference in Vancouver this week.

Poor people hold more traditional values toward marriage and divorce than people with moderate and higher incomes, UCLA psychologists report in the current issue of the Journal of Marriage and Family.

The findings are based on a large survey about marriage, relationships and values, analyzed across income groups. They raise questions about how effectively some $1billion in government spending to promote the value of marriage among the poor is being spent.

NEW YORK, NY (July 16, 2012) – A team of scientists at The New York Stem Cell Foundation (NYSCF) Laboratory led by Scott Noggle, PhD, NYSCF–Charles Evans Senior Research Fellow for Alzheimer's Disease, has developed the first cell-based model of Alzheimer's disease (AD) by reprogramming skin cells of Alzheimer's patients to become brain cells that are affected in Alzheimer's. This will allow researchers to work directly on living brain cells suffering from Alzheimer's, which until now had not been possible. Andrew Sproul, PhD, a postdoctoral associate in Dr.

Researchers at the University of Calgary have created a new, interactive tool that will change the way medical education is taught.

LINDSAY, named after Dr. Lindsay Kimmett, a bright, promising medical student who died in a car crash, is a virtual human that uses a variety of touch interfaces to help students learn anatomy and physiology in 3D.

SAN ANTONIO (July 16, 2012) — A novel technique for measuring tiny, rapid-fire secretions in the brains and mouthparts of fruit flies (drosophila) is providing insights into the beneficial effects of eating less — information that ultimately could help people suffering from neuromuscular disorders.

Using the method, researchers uncovered never-before-seen brain chemistry that helps explain why fruit flies genetically manipulated to mimic conditions such as Parkinson's disease and myasthenia gravis are more vigorous and live longer when fed a restricted diet.

ROCHESTER, Minn. -- Activity lingers longer in certain areas of the brain in those with Alzheimer's than it does in healthy people, Mayo Clinic researchers who created a map of the brain found. The results suggest varying brain activity may reduce the risk of Alzheimer's disease. The study, "Non-stationarity in the "Resting Brain's" Modular Architecture," was presented at the Alzheimer's Association International Conference and recently published in the journal PLoS One.

Can you teach an old dog (or human) new tricks? Yes, but it might take time, practice, and hard work before he or she gets it right, according to Hans Schroder and colleagues from Michigan State University in the US. Their work shows that when rules change, our attempts to control our actions are accompanied by a loss of attention to detail. Their work is published online in the Springer journal Cognitive, Affective, & Behavioral Neuroscience.
