Certain types of video games can help to train the brain to become more agile and improve strategic thinking, according to scientists from Queen Mary University of London and University College London (UCL).
The researchers recruited 72 volunteers and measured their 'cognitive flexibility' described as a person's ability to adapt and switch between tasks, and think about multiple ideas at a given time to solve problems.
A culturally tailored HIV prevention program developed and tested by investigators at UCLA and the Charles R. Drew University of Medicine and Science has been shown to significantly reduce unprotected sex among bisexual black men.
The innovative approach, called Men of African American Legacy Empowering Self, or MAALES, is described in an article in the peer-reviewed journal AIDS.
You take your piano lesson, you go to sleep and when you wake up your fingers are better able to play that beautiful sequence of notes. How does sleep make that difference? A new study helps to explain what happens in your brain during those fateful, restful hours when motor learning takes hold.
The concept behind gene therapy is simple: deliver a healthy gene to compensate for one that is mutated. New research published today in the Journal of Neuroscience suggests this approach may eventually be a feasible option to treat Rett Syndrome, the most disabling of the autism spectrum disorders. Gail Mandel, Ph.D., a Howard Hughes Investigator at Oregon Health and Sciences University, led the study.
SAN ANTONIO (Aug. 20, 2013) — Scientists today reported a possible basis for why food-restricted animals show increased susceptibility to drugs of abuse. This association has puzzled researchers since it was first observed more than three decades ago.
A new report* by biometric researchers at the National Institute of Standards and Technology (NIST) uses data from thousands of frequent travelers enrolled in an iris recognition program to determine that no consistent change occurs in the distinguishing texture of their irises for at least a decade. These findings inform identity program administrators on how often iris images need to be recaptured to maintain accuracy.
People with severe encephalitis — inflammation of the brain — are much more likely to die if they develop severe swelling in the brain, intractable seizures or low blood platelet counts, regardless of the cause of their illness, according to new Johns Hopkins research.
The Johns Hopkins investigators say the findings suggest that if physicians are on the lookout for these potentially reversible conditions and treat them aggressively at the first sign of trouble, patients are more likely to survive.
Alzheimer's disease has proven to be a difficult enemy to defeat. After all, aging is the No. 1 risk factor for the disorder, and there's no stopping that.
Most researchers believe the disease is caused by one of two proteins, one called tau, the other beta-amyloid. As we age, most scientists say, these proteins either disrupt signaling between neurons or simply kill them.
Now, a new UCLA study suggests a third possible cause: iron accumulation.
A new study led by Tel Aviv University researchers finds that the Holocaust education trips Israeli high school students take to Poland every year can trigger mental health problems.
About a third of the psychiatric professionals surveyed in this pilot study said they had treated teenagers for psychological problems arising from the Holocaust education trips. While most of the teenagers were treated for less severe symptoms such as anxiety, adjustment, and mood disorders, reports also cited hospitalization, post-traumatic-stress disorder, and psychosis.
Researchers at McGill University have found that sodium – the main chemical component in table salt – is a unique "on/off" switch for a major neurotransmitter receptor in the brain. This receptor, known as the kainate receptor, is fundamental for normal brain function and is implicated in numerous diseases, such as epilepsy and neuropathic pain.
A new publication in the top-ranked journal Neuron sheds new light onto the unknown processes on how the brain integrates the inputs from the different senses in the complex circuits formed by molecularly distinct types of nerve cells. The work was led by new Umeå University associate professor Paolo Medini.
A technique from the Capadona Lab at Case Western Reserve University accommodates two challenges inherent in brain-implantation technology, gauging the property changes that occur during implantation and measuring on a micro-scale. These new techniques open the doors for solving a great challenge for bioengineers — crafting a device that can withstand the physiological conditions in the brain for the long-term.
One of the most complex, contested and controversial questions confronting modern juvenile/youth justice systems concerns the minimum age of criminal responsibility: the age at which a child is deemed to be sufficiently 'mature' to be held responsible before the substantive criminal law.
This news release is available in French.
While children of all ages will be heading back to school in a few days, a new study from the Université de Montréal may encourage their parents to return to the classroom themselves ... at least for a few evenings! The results of a study in developmental psychology published in the Journal of Child and Family Studies show that the How-to Parenting Program improves the mental health of children.
INDIANAPOLIS -- Indiana University School of Medicine researchers have found a series of RNA biomarkers in blood that may help identify who is at risk for committing suicide.
In a study reported Aug. 20 in the advance online edition of the Nature Publishing Group journal Molecular Psychiatry, the researchers said the biomarkers were found at significantly higher levels in the blood of both bipolar disorder patients with thoughts of suicide as well in a group of people who had committed suicide.
