Using brain imaging to demonstrate weaker neural suppression for those with autism

According to the USA National Autism Association, people with autism spectrum disorder (ASD) may experience sensory hypersensitivity. A University of Minnesota Medical School researcher recently published an article in Nature Communications that illustrates why that may be true by showing the differences in visual motion perception in ASD are accompanied by weaker neural suppression in the visual cortex of the brain.

While experts in neuroscience and psychiatry recognize that differences in sensory functioning are common among people with ASD, it is not currently understood what is happening differently in the brain on a neural level to cause the variations in sensory perception.
