A new study on gaming and health in adolescents, conducted by researchers at Yale School of Medicine, found some significant gender differences linked to gaming as well as important health risks associated with problematic gaming. Published today in the journal Pediatrics, the study is among the first and largest to examine possible health links to gaming and problematic gaming in a community sample of adolescents.

Evidence from Disneyland suggests that human creativity may have evolved not in response to sexual selection as some scientists believe but as a way to help parents bond with their children and to pass on traditions and cultural knowledge, a new study published in the inaugural issue of the International Journal of Tourism Anthropology suggests.
SAN DIEGO — New human research suggests the chemical oxytocin — dubbed the "cuddle hormone" because of its importance in bonding between romantic partners and mothers and children — also influences feelings of well-being and sensitivity to advertising. Additional animal research shows that oxytocin may relieve stress and anxiety in social settings and may be more rewarding than cocaine to new mothers. The findings were presented at Neuroscience 2010, the Society for Neuroscience's annual meeting and the world's largest source of emerging news about brain science and health.
SAN DIEGO—New findings released today help identify the long-term impact of the prenatal environment and early parental care on the brain. Using animals as models, researchers help explain why early inflammation and a mother's exposure to drugs such as nicotine and high doses of pain killers have lasting consequences for children — and even future generations.
SAN DIEGO — New animal research helps explain why some eat without hunger or to excess. The studies explore the biological effects of poor eating habits, showing that high-fat diets cause lasting brain changes that may impair healthy eating. Additional studies show that food and drugs of abuse engage many of the same brain systems. The findings were presented at Neuroscience 2010, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health.
COLUMBUS, Ohio – The spleen, an organ that helps the body fight infections, might also be a source of the cells that end up doing more harm than good at the site of a spinal cord injury, new research suggests.
Considering the spleen's role in the after-effects of spinal cord injury could change the way researchers pursue potential treatments for these devastating injuries.
In the days and weeks after the spinal cord is damaged, a variety of cells travel to the wound site. In a typical wound, such as a cut on the skin, cells like this cooperate to promote healing.
Alzheimer's disease is widely believed to be caused by the gradual accumulation in the brain of amyloid-beta peptide which is toxic to nerve cells. Amyloid beta peptide is formed from a protein known as APP, which is found in three forms. Most research into APP – a key area of study for the disease – does not distinguish between the different forms of the protein.
SAN DIEGO — New tools inspired by video games are revealing how the brain senses and responds to its surroundings, finds new human and animal research. Taking advantage of state-of-the art technologies to track and mimic real-life environments, these studies show with new detail how the brain navigates, identifies, and remembers a setting. In additional human research, scientists apply these same technological advances to help people who have experienced strokes regain skills.
A Queen's University neuroscientist is launching a medical tool at the world's largest neuroscience conference in San Diego on Monday, Nov. 15.
The KINARM Assessment Station will greatly improve the way healthcare workers assess patients suffering from brain injuries and disease.
The new technology, invented by Stephen Scott, is the only objective tool for assessing brain function, and clinical researchers need this tool to develop better therapies for treating brain injury or disease.
San Diego - How do you know what to listen to? In the middle of a noisy party, how does a mother suddenly focus on a child's cry, even if it isn't her own?
Bridget Queenan, a doctoral candidate in neuroscience at Georgetown University Medical Center is turning to mustached bats to help her solve this puzzle.
San Diego - Neuroscientists at Georgetown University Medical Center can now show, using functional MRI images, why it is that behavior in children and young adolescents veers toward the egocentric rather than the introspective.
In findings being presented at the annual meeting of the Society for Neuroscience in San Diego on November 14, the researchers say that the five scattered regions in the brain that make up the default-mode network (DMN) have not started working in concert in youngsters aged six to nine. These areas light up in an fMRI scan, but not simultaneously.
The twisting, ladder-like form of the DNA molecule—the architectural floor plan of life—contains a universe of information critical to human health. Enormous effort has been invested in deciphering the genetic code, including, most famously, the Human Genome Project. Nevertheless, the process of reading some three-billion nucleotide "letters" to reveal an individual's full genome remains a costly and complex undertaking.
Low levels of vitamin D, the essential nutrient obtained from milk, fortified cereals and exposure to sunlight, doubles the risk of stroke in whites, but not in blacks, according to a new report by researchers at Johns Hopkins.
Stroke is the nation's third leading cause of death, killing more than 140,000 Americans annually and temporarily or permanently disabling over half a million when there is a loss of blood flow to the brain.
San Diego - A brain scan with functional MRI (fMRI) is enough to predict which patients with pediatric anxiety disorder will respond to "talk therapy," and so may not need to use psychiatric medication, say neuroscientists from Georgetown University Medical Center.
Their study, being presented at the annual meeting of the Society for Neuroscience in San Diego, showed that children and adolescents, ages 8 to16, who show fear when looking at happy faces on a screen inside an fMRI scanner were those who had least success with an eight-week course of cognitive behavioral therapy.
