UCLA study links immune protein to abnormal brain development

UCLA scientists have discovered that exposing fetal neurons to higher than normal levels of a common immune protein leads to abnormal brain development in mice.

Published Oct. 14 in the online Journal of Neuroimmunology, the finding may provide new insights into factors contributing to human neurological disorders like schizophrenia and autism.

Psychological first aid for survivors of disaster

Even as we breathe a sigh of relief watching the rescue of 33 miners trapped in a Chilean mine for more than two months, there is recognition that their recovery from this traumatic experience involves more than just their physical health. Survivors of disasters are at significant risk for such problems as post-traumatic-stress-disorder (PTSD), depression, anxiety, and substance abuse.

I want to see what you see: Babies treat 'social robots' as sentient beings

 Babies treat 'social robots' as sentient beings

Babies are curious about nearly everything, and they're especially interested in what their adult companions are doing. Touch your tummy, they'll touch their own tummies. Wave your hands in the air, they'll wave their own hands. Turn your head to look at a toy, they'll follow your eyes to see what's so exciting.

Key to blood-brain barrier opens way for treating Alzheimer's and stroke

While the blood-brain barrier (BBB) protects the brain from harmful chemicals occurring naturally in the blood, it also obstructs the transport of drugs to the brain. In an article in Nature scientists at the Swedish medical university Karolinska Institutet now present a potential solution to the problem. The key to the BBB is a cell-type in the blood vessel walls called pericytes, and the researchers hope that their findings will one day contribute to new therapies for diseases like Alzheimer's and stroke.

New malware could steal users social media behavior and info -- Ben-Gurion U. researchers

BEER-SHEVA, ISRAEL, October 14, 2010 -- A new study by Ben-Gurion University of the Negev (BGU) researchers predicts that a new generation of malware (software written for malicious purposes like identity theft) could steal data on human behavior patterns, which is more dangerous than traditional, detectable attacks.

Love takes up where pain leaves off, Stanford brain study shows

STANFORD, Calif. — Intense, passionate feelings of love can provide amazingly effective pain relief, similar to painkillers or such illicit drugs as cocaine, according to a new Stanford University School of Medicine study.

Walk much? It may protect your memory down the road

ST. PAUL, Minn. – New research suggests that walking at least six miles per week may protect brain size and in turn, preserve memory in old age, according to a study published in the October 13, 2010, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Luteolin compound reduces age-related memory deficits

Luteolin compound reduces age-related memory deficits

CHAMPAIGN, lll. — A diet rich in the plant compound luteolin reduces age-related inflammation in the brain and related memory deficits by directly inhibiting the release of inflammatory molecules in the brain, researchers report.

Luteolin (LOOT-ee-oh-lin) is found in many plants, including carrots, peppers, celery, olive oil, peppermint, rosemary and chamomile.

I win, you lose: Brain imaging reveals how we learn from our competitors

 Brain imaging reveals how we learn from our competitors

Learning from competitors is a critically important form of learning for animals and humans. A new study has used brain imaging to reveal how people and animals learn from failure and success.

Train a computer to classify pictures and videos based on the elements that they contain

University of Granada researchers have developed a new computer technique that allows to "train" computers to interpret the visual contents of a video or picture. This advance will allow to classify automatically pictures basing on whether individuals or specific objects are present in such images. Videos can also be classified according to specific poses.

Early role of mitochondria in AD may help explain limitations to current beta amyloid hypothesis

(NEW YORK, NY, October 13, 2010) – Before Alzheimer's patients experience memory loss, the brain's neurons have already suffered harm for years.

A new study in mouse models by researchers at Columbia University Medical Center has found that the brain's mitochondria -- the powerhouses of the cell -- are one of the earliest casualties of the disease. The study, which appeared in the online Early Edition of PNAS, also found that impaired mitochondria then injure the neurons' synapses, which are necessary for normal brain function.

Researchers reach consensus on use of deep brain stimulation to treat Parkinson's

Since the late 1990s, deep brain stimulation (DBS) has proven to be a lifeline for some patients suffering from Parkinson's disease, a cruel neurological disorder that can cause lack of control over movement, poor balance and coordination, and rigidity, among other symptoms.

UMD neuroscientists discover nicotine could play role in Alzheimer's disease therapy

A team of neuroscientists has discovered important new information in the search for an effective treatment for Alzheimer's disease, the debilitating neurological disorder that afflicts more than 5.3 million Americans and is the sixth-leading cause of death in the United States. Hey-Kyoung Lee, associate professor in the University of Maryland Department of Biology, and her research team have shown that they may be able to eliminate debilitating side effects caused by a promising Alzheimer's drug by stimulating the brain's nicotine receptors.
