People with autism spectrum disorders commonly have difficulty processing sensory information, which can make busy, bright or loud settings—such as schools, airports and restaurants—stressful or even painful. The neurological causes for altered sound processing are complex, and researchers are interested in better understanding them to make life better for people with autism.
In a study that combines behavioral tests, computer models and electrophysiological recordings of neuron activity, researchers have found that hyperactivity of neurons in the auditory cortex and the reaction of these neurons to an unusually broad range of frequencies contribute to this altered sound processing in rat models. The research is published in the journal PLOS Biology.
“One of the things we thought wasn’t being looked at enough was this idea of sensory discrimination: being able to distinguish between different features in our environment,” said Benjamin Auerbach, a professor of molecular and integrative physiology at the University of Illinois Urbana-Champaign.
