How could the current financial crisis have happened? While fingers have been pointing to greedy banks, subprime-loan officers, and sloppy credit card practices, these are not the only contributors to the economic downturn. A new report in Psychological Science in the Public Interest, a journal of the Association for Psychological Science, examines the psychology of financial decision making, including the role of risk in making economic choices, how individuals behave in stock and credit markets, and how financial crises impact people's well-being.

ROCHESTER, Minn. -- A new Mayo Clinic study found that nerve inflammation may cause the pain, numbness and weakness following surgical procedures that is known as postsurgical neuropathy. The development of postsurgical neuropathies is typically attributed to compression or stretching of nerves during surgery. This new research shows that, in some cases, the neuropathy is actually caused by the immune system attacking the nerves and is potentially treatable with immunosuppressive drugs. The study was published in this month's issue of Brain.

A Dutch-German medical research team led by Harald Schmidt from Maastricht University, Netherlands, and Christoph Kleinschnitz, University of Würzburg, Germany, has discovered that an enzyme is responsible for the death of nerve cells after a stroke. The enzyme NOX4 produces hydrogen peroxide, a caustic molecule also used in bleaching agents. Inhibition of NOX4 by an experimental new drug in mice with stroke dramatically reduces brain damage and preserves brain functions, even when given hours after the stroke.

Broca's region is classically regarded as the motor centre for speech. Our ability to form phonemes and words is controlled here. According to the maps of the cerebral cortex developed by Korbinian Brodmann, which are still in use today, Broca's region is composed of two areas. Over the last few years, however, researchers have begun to question this subdivision as a result of experience gained in clinical studies and the findings of magnetic resonance imaging analyses.

For advanced activities of our daily life (such as driving a car, or seeing a movie), to be awake is important. It has been known so far that neuropeptide in the brain called "Orexin"controls sleep and awakening besides appetite. Here, the research group led by Dr. Akihiro Yamanaka, National Institute for Physiological Sciences (NIPS), found that orexin-releasing neurons have the self-excitation mechanism that activate each other among them, and maintain awaking. From this result, the application to doze prevention or insomnia treatment can be expected.

(CHICAGO) – Neurological researchers at Rush University Medical Center have found a new therapeutic target that can potentially lead to a new way to prevent the progression of Alzheimer's disease. The target called neutral sphingomyelinase (N-SMase) is a protein that when activated, can cause a chain of reactions in the cell leading to neuronal death and memory loss.

Results from the study funded by the National Institutes of Health and the Alzheimer's Association will be published in the September 22 issue of the Journal of Neuroscience.

Ever meet a kindergartener who seemed naturally compassionate and cared about others' feelings? Who was cooperative and didn't demand his own way? Chances are, his parents held, carried and cuddled him a lot; he most likely was breastfed; he probably routinely slept with his parents; and he likely was encouraged to play outdoors with other children, according to new research findings from the University of Notre Dame.

CHAMPAIGN, lll. – Researchers have found an association between physical fitness and the brain in 9- and 10-year-old children: Those who are more fit tend to have a bigger hippocampus and perform better on a test of memory than their less-fit peers.

Grabbing a child firmly by the arm, yelling and repeatedly punishing him or her may not be without long-terms risks, according to researchers from the Université de Montréal. They are studying how this harsh parenting can impair the emotional development of a child, possibly leading to anxiety disorders such as social phobia, separation anxiety and panic attacks.

Impulsive behaviour can be improved with training and the improvement is marked by specific brain changes, according to a new Queen's University study.

A research team led by neuroscience PhD student Scott Hayton has pinpointed the area of the brain that controls impulsive behavior and the mechanisms that affect how impulsive behavior is learned. The findings could have a significant impact on the diagnosis and treatment of several disorders and addictions, including ADHD and alcoholism.

TORONTO, ON – Talking to yourself might not be a bad thing, especially when it comes to exercising self control.

New research out of the University of Toronto Scarborough – published in this month's edition of Acta Psychologica – shows that using your inner voice plays an important role in controlling impulsive behaviour.

Researchers at Mount Sinai School of Medicine have found that the naturally-occurring hormone oxytocin selectively improves social cognitive abilities for less socially proficient individuals, but has little effect on those who are more socially proficient. The study was published today in Psychological Science.

Billions of brain cells are communicating at any given moment. Like an organic supercomputer they keep everything going, from breathing to solving riddles, and "programming errors" can lead to serious conditions such as schizophrenia, Parkinson's disease and attention-deficit hyperactivity disorder.

Tampa, Fla. (Sept. 21, 2010) – Two University of South Florida stem cell researchers propose creating an independent national "Stem Cell Research Ethics Consortium" to provide better guidance on stem cell issues for regulatory agencies, law makers and policy makers.

Their recommendation is timely, and came before the recent ruling by a U.S. judge that halted expansion of federal funding for embryonic stem cell research. The ruling reversed the attempt to overturn the standing moratorium on federal funding for such research and subsequent appeals.
