"The brain's processing of social information is performed by a network of areas, some of which are frontal, and some of which are posterior," Just explained. "Social impairments in autism are likely caused by the poor frontal-posterior connectivity. Similarly, language comprehension is performed by a network of frontal and posterior areas, and once again, poor connectivity may impair that network's functioning."

(Boston) - An article by researchers from Boston University School of Medicine (BUSM), New York Medical College (NYMC), and the Columbia College of Physicians and Surgeons (CCPS) reviews evidence that yoga may be effective in treating patients with stress-related psychological and medical conditions such as depression, anxiety, high blood pressure and cardiac disease. Their theory, which currently appears online in Medical Hypotheses, could be used to develop specific mind-body practices for the prevention and treatment of these conditions in conjunction with standard treatments.
Charlottesville, VA (March 6, 2012). Clinicians from the University of Utah report the death of a patient who received a mild brain injury from a ground-level fall while taking the new anticoagulant dabigatran etexilate for non–valve related atrial fibrillation. The authors describe the events that led from a mild traumatic brain injury to the man's death, the largely irreversible dangers of massive hemorrhage from direct thrombin inhibitors such as dabigatran, and the few management options that can be used to counteract this "uncontrollable" bleeding.
Charlottesville, VA (March 6, 2012). Researchers at the Perelman School of Medicine at the University of Pennsylvania have demonstrated that aggressive treatment of severe traumatic brain injury, which includes invasive monitoring of intracranial pressure (ICP) and decompressive craniectomy, produces better patient outcomes than less aggressive measures and is cost-effective in patients no matter their age––even in patients 80 years of age. These important findings can be found in the article "Is aggressive treatment of traumatic brain injury cost-effective?
PHILADELPHIA – Aggressive treatment for severe traumatic brain injuries costs more than routine care, yet yields significantly better outcomes, improved quality of life, and lower long term care costs, according to a new study by researchers in the Perelman School of Medicine at the University of Pennsylvania. For example, in 20 year old traumatic brain injury survivor, aggressive care leads to significantly improved outcomes and costs nearly $100,000 less compared to routine care.
ROCHESTER, Minn. -- Mayo Clinic researchers this week will announce the use of the blood pressure drug prazosin as an effective treatment to curb post- traumatic stress disorder (PTSD)-related nightmares.
In a presentation during the 20th European Congress of Psychiatry in Prague, Mayo Clinic psychiatrists will present a systematic literature review of prazosin in the treatment of nightmares. Researchers investigated 12 prazosin studies, four of which were randomized controlled trials.
WINSTON-SALEM, N.C. – March 5, 2012 – The brain has a remarkable ability to learn new cognitive tasks while maintaining previously acquired knowledge about various functions necessary for everyday life. But exactly how new information is incorporated into brain systems that control cognitive functions has remained a mystery.
COLUMBUS, Ohio – Middle- and high-school students who bully their classmates are more likely than others to use substances such as cigarettes, alcohol and marijuana, a new study found.
Researchers found that bullies and bully-victims – youth who are both perpetrators and victims – were more likely to use substances than were victims and non-involved youth.
"Our findings suggest that one deviant behavior may be related to another," said Kisha Radliff, lead author of the study and assistant professor of school psychology at Ohio State University.
New research from the University of California shows how the ability to detect light could have evolved before anything like an eye.
As published today (March 5) in the journal BMC Biology, the research is based on the stinging mechanism in the tiny, brainless and eyeless freshwater polyp Hydra magnipapillata. Part of a group of animals called cnidarians that includes sea anemones, corals and jellyfish, a hydra is essentially a mouth surrounded by tentacles armed with stinging cells, or cnidocytes.
Studying tiny bits of genetic material that control protein formation in the brain, Johns Hopkins scientists say they have new clues to how memories are made and how drugs might someday be used to stop disruptions in the process that lead to mental illness and brain wasting diseases.
It takes two to tango. Two hemispheres of your brain, that is.
USC researchers are working to pin down the exact source of creativity in the brain – and have found that the left hemisphere of your brain, thought to be the logic and math portion, actually plays a critical role in creative thinking.
"We want to know: how does creativity work in the brain?" said Lisa Aziz-Zadeh, assistant professor of neuroscience at the USC Dornsife College of Letters, Arts and Sciences.
Without looking down, Kira runs her index finger across the screen of an Android tablet that she is holding in her lap. For the occasion, she has painted her fingernails bright pink. When her finger touches a line drawn on the screen, the tablet vibrates quietly. Scanning her finger back and forth and feeling the vibration come and go allows her to trace the line's path. When her finger reaches a pink dot, the tablet gives off an electronic tone and she grins delightedly.
A new study from the Université de Montréal shows an increase in prevalence of Canadian children diagnosed with attention-deficit hyperactivity disorder (ADHD) and in the use of medications associated with ADHD in school-age children.
WASHINGTON – Men like to know when their wife or girlfriend is happy while women really want the man in their life to know when they are upset, according to a new study published by the American Psychological Association.
The study involved a diverse sample of couples and found that men's and women's perceptions of their significant other's empathy, and their abilities to tell when the other is happy or upset, are linked to relationship satisfaction in distinctive ways, according to the article published online in the Journal of Family Psychology.
LMU researchers developed a new strategy for the treatment of stroke, which could help to improve blood flow to ischemic brain. Strokes are due to a localized reduction in the blood supply to the brain, mainly due to the blockage of a vessel by a blood clot. This can lead to the death and irreversible loss of nerve cells. In about 90% of cases, no dedicated treatment is available that can effectively prevent serious damage following an acute stroke.
