Auditory-evoked field values were obtained from 18 boys (nine with and nine without auditory hypersensitivity) with autistic spectrum disorder and 12 age-matched controls. Autistic disorder with hypersensitivity showed significantly more delayed M50/M100 peak latencies than autistic disorder without hypersensitivity or the control. M50 dipole moments in the hypersensitivity group were statistically larger than those in the other two groups. M50/M100 peak latencies were correlated with the severity of auditory hypersensitivity; furthermore, severe hypersensitivity induced more behavioral problems. This study indicates auditory hypersensitivity in autistic spectrum disorder as a characteristic response of the primary auditory cortex, possibly resulting from neurological immaturity or functional abnormalities in it. Erratum NeuroReport 2012, 23:698 The authors of the article ‘Differential responses of primary auditory cortex in autistic spectrum disorder with auditory hypersensitivity’ published in issue 2 in January 2012 have noticed an error in one of the sentences in the abstract of this article which reads: ‘M50 dipole moments in the hypersensitivity group were statistically larger than those in the other two groups’. ‘Statistically’ should be deleted and the sentence should read: ‘M50 dipole moments in the hypersensitivity group were larger than those in the other two groups’. The authors apologize for this error. NeuroReport. 23(11):698, August 1, 2012. © 2012 Lippincott Williams & Wilkins, Inc.
