Overview

Objective: Sensory overresponsivity (SOR), an atypical negative reaction to sensory stimuli, is highly prevalent in autism spectrum disorder (ASD). Previous work has related SOR to increased brain response in sensory-limbic regions. This study investigated where these atypical responses fall in three fundamental stages of sensory processing: arousal (i.e., initial response), habituation (i.e., change in response over time), and generalization of response to novel stimuli. Different areas of atypical response would require distinct intervention approaches.

Methods: Functional MRI was used to examine these patterns of neural habituation to two sets of similar mildly aversive auditory and tactile stimuli in 42 high-functioning children and adolescents with ASD (21 with high levels of SOR and 21 with low levels of SOR) and 27 age-matched typically developing youths (ages 8–17). The relationship between SOR and change in amygdala-prefrontal functional connectivity across the sensory stimulation was also examined.
