Recent research has highlighted atypical reactivity to sensory stimulation as a core symptom
in children with autism spectrum disorder (ASD). However, little is known about the
dysfunctional neurological mechanisms underlying these aberrant sensitivities. Here we
tested the hypothesis that the ability to filter out auditory repeated information is deficient in
children with ASD already from subcortical levels, yielding to auditory sensitivities. We
recorded the frequency-following response (FFR), a non-invasive measure of the neural …
