Sanford-Burnham researchers discover the molecular basis of autistic symptoms in children with a rare bone disorder -- findings that also provide new insights for the general autistic population Children with multiple hereditary exostoses (MHE), an inherited genetic disease, suffer from multiple growths on their bones that cause pain and disfigurement. But beyond the physical symptoms of this condition, some parents have long observed that their children with MHE also experience...

Findings in animals could lead to new treatments for people suffering from anxiety disorders, including post-traumatic stress disorder Rutgers scientists have uncovered genetic clues as to why some mice no longer in danger are still fearful while others are resilient to traumatic experiences — knowledge that could help those suffering with crippling anxiety and PTSD. "Our work with mice demonstrates how genes play a role in developing and extinguishing pathological fear like Post...

In a 2007 episode of the television show Boston Legal, a character claimed to have figured out that a cop was racist because his amygdala activated — displaying fear, when they showed him pictures of black people. This link between the amygdala and fear — especially a fear of others unlike us, has gone too far, not only in pop culture, but also in psychological science, say the authors of a new paper which will be published in the February issue of Current Directions in...

In the classic film "12 Angry Men," Henry Fonda's character sways a jury with his quiet, persistent intelligence. But would he have succeeded if he had allowed himself to fall sway to the social dynamics of that jury? Research led by scientists at the Virginia Tech Carilion Research Institute found that small-group dynamics -- such as jury deliberations, collective bargaining sessions, and cocktail parties -- can alter the expression of IQ in some susceptible people. "You may joke about...

The study, initiated by the Swiss researchers and published in Nature, constitutes ground-breaking work in exploring emotions in the brain. Anxiety disorders constitute a complex family of pathologies affecting about 10% of adults. Patients suffering from such disorders fear certain situations or objects to exaggerated extents totally out of proportion to the real danger they present. The amygdala, a deep-brain structure, plays a key part in processing fear and anxiety. Its functioning can...

Domestic Violence Triggers Brain Changes In Children

Children exposed to family violence show the same pattern of activity in their brains as soldiers exposed to combat, according to a new study published Monday in the journal Current Biology. The study is the first to use brain scans, or functional magnetic resonance imaging (fMRI), to investigate the impact of physical abuse and domestic violence on children´s emotional development. Scientists at University College London found that exposure to family violence was associated with...

Finding offers new insights into neural basis of social perception Responding to faces is a critical tool for social interactions between humans. Without the ability to read faces and their expressions, it would be hard to tell friends from strangers upon first glance, let alone a sad person from a happy one. Now, neuroscientists from the California Institute of Technology (Caltech), with the help of collaborators at Huntington Memorial Hospital in Pasadena and Cedars-Sinai Medical Center...

  Cannabinoids (marijuana) administration after experiencing a traumatic event blocks the development of post-traumatic stress disorder (PTSD)-like symptoms in rats, according to a new study conducted at the University of Haifa and published in the journal Neuropsychopharmacology. “We found that there is a ℠window of opportunity´ during which administering synthetic marijuana helps deal with symptoms simulating PTSD in rats,” said Dr. Irit Akirav of the...
