Brain Function Differences in Language Processing in Children and Adults with Autism / Diane L. WILLIAMS in Autism Research, 6-4 (August 2013)
[article]
Titre : Brain Function Differences in Language Processing in Children and Adults with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Diane L. WILLIAMS, Auteur ; Vladimir L. CHERKASSKY, Auteur ; Robert A. MASON, Auteur ; Timothy A. KELLER, Auteur ; Nancy J. MINSHEW, Auteur ; Marcel Adam JUST, Auteur Article en page(s) : p.288-302 Langues : Anglais (eng) Mots-clés : FMRI language processing development functional connectivity Index. décimale : PER Périodiques Résumé : Comparison of brain function between children and adults with autism provides an understanding of the effects of the disorder and associated maturational differences on language processing. Functional imaging (functional magnetic resonance imaging) was used to examine brain activation and cortical synchronization during the processing of literal and ironic texts in 15 children with autism, 14 children with typical development, 13 adults with autism, and 12 adult controls. Both the children and adults with autism had lower functional connectivity (synchronization of brain activity among activated areas) than their age and ability comparison group in the left hemisphere language network during irony processing, and neither autism group had an increase in functional connectivity in response to increased task demands. Activation differences for the literal and irony conditions occurred in key language-processing regions (left middle temporal, left pars triangularis, left pars opercularis, left medial frontal, and right middle temporal). The children and adults with autism differed from each other in the use of some brain regions during the irony task, with the adults with autism having activation levels similar to those of the control groups. Overall, the children and adults with autism differed from the adult and child controls in (a) the degree of network coordination, (b) the distribution of the workload among member nodes, and (3) the dynamic recruitment of regions in response to text content. Moreover, the differences between the two autism age groups may be indicative of positive changes in the neural function related to language processing associated with maturation and/or educational experience.
