The study was published in the current issue of the Journal of Autism and Developmental Disorders by Yale Child Study Center researchers Fred Volkmar, M.D., Kevin A. Pelphrey, and their colleagues.
The results suggest that brain systems supporting social perception respond well to an early intervention behavioral program called pivotal response treatment. This treatment includes parent training, and employs play in its methods.
ASDs are complex neurobiological disorders that inhibit a person's ability to communicate and develop social relationships, and are often accompanied by behavioral challenges. Until recently, autism diagnosis typically did not occur until a child was about three- to five-years-old, and treatment programs were geared for this older age group. Today, Volkmar and his team are diagnosing children as young as age one. Pivotal response treatment, developed at the University of California-Santa Barbara, combines developmental aspects of learning and development, and is easy to implement in children younger than age two.
In the current study, the team used functional magnetic resonance imaging — for the first time — to measure changes in brain activity after two five-year-olds with ASD received pivotal response treatment. Study co-author Pamela Ventola used this treatment method to identify distinct behavioral goals for each child in the study, and then reinforced these targeted skills with treatment involving motivational play activities.
The team found that children who received this treatment showed improvements in behavior, and being able to talk to other people. In addition, the MRI and electroencephalogram revealed increased brain activity in the regions supporting social perception.
Their results are from two children, but the researchers are currently conducting a full-scale study of 60 children. Pelphrey said that while both children in the current study received the same type of treatment for ASD, the results were not homogenous because ASD is a multi-faceted disorder that has a unique effect on each child. Some children with ASD function on a higher level than others, for example.
"ASD is a heterogeneous disorder, and research aimed at understanding treatment must address this heterogeneity," said Pelphrey. "Both the children in our current study made progress, but their degree of progress and level of skills at the end of treatment were distinct."Volkmar sees these results as a first step in a novel approach to treatment planning. "Autism research has come a long way," he said. "These findings are exciting because they show that early intervention works in autism."
Funding for the study came from the Harris Professorship at Yale Child Study Center given to Kevin A. Pelphrey; Allied World; and National Institute of Mental Health grant K23MH86785. This research was also made possible by CTSA Grant Number UL1 RR024139 from the National Center for Advancing Translational Sciences (NCATS), a component of the National Institutes of Health (NIH), and NIH roadmap for Medical Research.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
