Multisensory processing in children with autism: high-density electrical mapping of auditory–somatosensory integration / Natalie RUSSO in Autism Research, 3-5 (October 2010)
[article]
Titre : Multisensory processing in children with autism: high-density electrical mapping of auditory–somatosensory integration Type de document : Texte imprimé et/ou numérique Auteurs : Natalie RUSSO, Auteur ; John J. FOXE, Auteur ; Alice B. BRANDWEIN, Auteur ; Ted ALTSCHULER, Auteur ; Hilary GOMES, Auteur ; Sophie MOLHOLM, Auteur Année de publication : 2010 Article en page(s) : p.253-267 Langues : Anglais (eng) Mots-clés : autism spectrum disorders electrophysiology multisensory integration auditory processing somatosensory processing development Index. décimale : PER Périodiques Résumé : Successful integration of signals from the various sensory systems is crucial for normal sensory–perceptual functioning, allowing for the perception of coherent objects rather than a disconnected cluster of fragmented features. Several prominent theories of autism suggest that automatic integration is impaired in this population, but there have been few empirical tests of this thesis. A standard electrophysiological metric of multisensory integration (MSI) was used to test the integrity of auditory–somatosensory integration in children with autism (N=17, aged 6–16 years), compared to age- and IQ-matched typically developing (TD) children. High-density electrophysiology was recorded while participants were presented with either auditory or somatosensory stimuli alone (unisensory conditions), or as a combined auditory–somatosensory stimulus (multisensory condition), in randomized order. Participants watched a silent movie during testing, ignoring concurrent stimulation. Significant differences between neural responses to the multisensory auditory–somatosensory stimulus and the unisensory stimuli (the sum of the responses to the auditory and somatosensory stimuli when presented alone) served as the dependent measure. The data revealed group differences in the integration of auditory and somatosensory information that appeared at around 175 ms, and were characterized by the presence of MSI for the TD but not the autism spectrum disorder (ASD) children. Overall, MSI was less extensive in the ASD group. These findings are discussed within the framework of current knowledge of MSI in typical development as well as in relation to theories of ASD.

Titre : Neurophysiological Indices of Atypical Auditory Processing and Multisensory Integration are Associated with Symptom Severity in Autism Type de document : Texte imprimé et/ou numérique Auteurs : Alice B. BRANDWEIN, Auteur ; John J. FOXE, Auteur ; John S. BUTLER, Auteur ; Hans-Peter FREY, Auteur ; Juliana C. BATES, Auteur ; Lisa H. SHULMAN, Auteur ; Sophie MOLHOLM, Auteur Article en page(s) : p.230-244 Langues : Anglais (eng) Mots-clés : Electrophysiology ERP ASD Multisensory integration ADOS Sensory Profile Index. décimale : PER Périodiques Résumé : Atypical processing and integration of sensory inputs are hypothesized to play a role in unusual sensory reactions and social-cognitive deficits in autism spectrum disorder (ASD). Reports on the relationship between objective metrics of sensory processing and clinical symptoms, however, are surprisingly sparse. Here we examined the relationship between neurophysiological assays of sensory processing and (1) autism severity and (2) sensory sensitivities, in individuals with ASD aged 6–17. Multiple linear regression indicated significant associations between neural markers of auditory processing and multisensory integration, and autism severity. No such relationships were apparent for clinical measures of visual/auditory sensitivities. These data support that aberrant early sensory processing contributes to autism symptoms, and reveal the potential of electrophysiology to objectively subtype autism.
