Tel Aviv -- Although we're convinced that baby is brilliant when she mutters her first words, cognitive scientists have been conducting a decades-long debate about whether or not human beings actually "learn" language.

The study, published in the Journal of Clinical Investigation, reveals that damaged alpha-synuclein proteins (which are implicated in Parkinson's disease) can spread in a 'prion-like' manner, an infection model previously described for diseases such as BSE (mad cow disease).

MADISON — A cold dose of fear lends an edge to the here-and-now — say, when things go bump in the night.

"That edge sounds good. It sounds adaptive. It sounds like perception is enhanced and that it can keep you safe in the face of danger," says Alexander Shackman, a researcher at the University of Wisconsin-Madison.

But it sounds like there's also a catch, one that Shackman and his coauthors — including Richard Davidson, UW-Madison psychology and psychiatry professor — described in the Jan. 19 Journal of Neuroscience.

Case Western Reserve University School of Medicine and Athersys, Inc. (NASDAQ: ATHX) announced a joint scientific study on spinal cord injury will be published today in the January issue of the Journal of Neuroscience. The study, by leading researchers from the Department of Neurosciences at the School of Medicine and scientists at Athersys, presents data supporting the potential therapeutic benefit of Athersys' MultiStem® program for spinal cord injury.

TORONTO, ON –Adult children of divorce are more likely to have seriously considered suicide than their peers from intact families, suggests new research from the University of Toronto

A study led by Dr. Tom P. Aufderheide, professor of emergency medicine at The Medical College of Wisconsin, shows an alternative method of cardio-pulmonary resuscitation increases long-term survival of patients.

Seeing actors smoke in a movie activated the brain areas of smokers that are known to interpret and plan hand movements, as though they too were about to light a cigarette, according to a new study in the Jan. 19 issue of The Journal of Neuroscience.

• Extract from the kudzu root has long been thought to be a remedy for alcoholism
• However, since the precise mechanism of action is unknown, a new study set out to unravel its mystery
• The results show that the participants treated with kudzu experienced no adverse consequences that could decrease alcohol intake

Preliminary research suggests that use of a type of molecular imaging procedure may have the ability to detect the presence of beta-amyloid in the brains of individuals during life, a biomarker that is identified during autopsy to confirm a diagnosis of Alzheimer disease, according to a study in the January 19 issue of JAMA.

A new study at Rochester Institute of Technology indicates that the incidence of maltreatment, including neglect and physical and sexual abuse, is more than 25 percent higher among deaf and hard-of-hearing children than among hearing youths. The research also shows a direct correlation between childhood maltreatment and higher rates of negative cognition, depression and post-traumatic stress in adulthood.

CAMBRIDGE, Mass., Jan. 18, 2011 -- Physicists and bioengineers have developed an optical instrument allowing them to control the behavior of a worm just by shining a tightly focused beam of light at individual neurons inside the organism.

CHAPEL HILL, N.C. – Researchers at the University of North Carolina at Chapel Hill have discovered a molecule that can make brain cells resistant to programmed cell death or apoptosis.

Changes within deep regions of the brain can now be visualized at the cellular level, based on research on mice, which was funded by the National Institutes of Health. Published Sunday in Nature Medicine, the study used a groundbreaking technique to explore cellular-level changes over a period of weeks within deep brain regions, providing a level of detail not possible with previously available methods. The study was supported by the National Institute on Drug Abuse (NIDA), the National Cancer Institute, and the National Institute of Neurological Disorders and Stroke.
