Sensory symptoms are common in autism and may result from differences in sensory processing. The locus coeruleus-norepinephrine (LC-NE) system modulates sensory processing by increasing selectivity to salience. To specify this mechanism, we manipulated LC-NE activity and explored sensory selectivity in autistic and non-autistic adolescents. We assessed pupillometry and electroencephalography (EEG) in 52 autistic adolescents (ASD), 55 healthy controls (CON), and 43 adolescents with other mental…
