Links between sensory and motor brain networks may be unusually weak in individuals with autism.
Some children diagnosed with autism by age 2 show unusual responses to sights, sounds and textures as infants.
Stimulating the vagus nerve may normalize the brain response to sound in a rat model of Rett syndrome. It may also improve rats’ behavioral response to certain speech sounds.
Adding motor and sensory data boosts the accuracy of Research Domain Criteria — a broad research framework adopted by the U.S. National Institute of Mental Health — for predicting autism.
Tracking how roundworms crawl has enabled scientists to determine that many autism genes are involved in sensory processing and learning.
Girls and boys with autism show different patterns of brain activity in response to sensory stimuli.
