Researchers at the University of Louisville are getting $900,000 from the National Institutes of Health to continue their clinical study of autism.U of L neuroscientist Dr. Manuel Casanova says the NIH award will fund a four-year clinical trial that involves the use of a magnetic field to improve brain function and reduce some of the symptoms associated with autism, such as tantrums and repetitive behaviors."We are trying to induce current through pathways that are not being properly used in the cortex of patients with autism," he said.Dr. Casanova says in the trials, the magnetic stimulation will be paired with a behavior intervention in an effort to help patients better relate to other people.
