JAMA Psychiatry published research on the neurobiological basis of sensory overresponsivity (an extreme negative reaction to sensory stimuli) in youth with autism.  Since more than half of youth with autism spectrum disorders (ASDs) have sensory overresponsivity (SOR)  the researchers wanted to use functional magnetic resonance imaging to investigate the differences in brain responses, habituation, and connectivity during […]

A Northwestern University study researched how children processed three sounds with background noise present in the room. The three sounds, “ba”, “ga” and “da” were difficult for children to interpret. The researchers used a new technology that is sensitive enough to measure how the nervous system represents differences in sounds in each person. This study […]
