The Neurobiology of Semantic Processing in Autism Spectrum Disorder: An Activation Likelihood Estimation Analysis / L. PHAN in Journal of Autism and Developmental Disorders, 51-9 (September 2021)
[article]
Titre : The Neurobiology of Semantic Processing in Autism Spectrum Disorder: An Activation Likelihood Estimation Analysis Type de document : Texte imprimé et/ou numérique Auteurs : L. PHAN, Auteur ; A. TARIQ, Auteur ; G. LAM, Auteur ; Elizabeth W. PANG, Auteur ; C. ALAIN, Auteur Article en page(s) : p.3266-3279 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder Brain/diagnostic imaging Brain Mapping Humans Likelihood Functions Magnetic Resonance Imaging Semantics Activation likelihood estimation Autism spectrum disorder Functional magnetic resonance imaging (fMRI) Left inferior frontal gyrus Semantic processing Index. décimale : PER Périodiques Résumé : Semantic processing impairments are present in a proportion of individuals with autism spectrum disorder (ASD). Despite the numerous imaging studies investigating this language domain in ASD, there is a lack of consensus regarding the brain structures showing abnormal pattern of activity. This meta-analysis aimed to identify neural activation patterns present during semantic processing in ASD. Findings reveal activation of areas associated with semantic processing and executive functions in ASD. However, the activation was less concise in comparison to controls and there was less activation in the right hemisphere and in areas associated with executive functions. This provides strong support for impaired semantic processing in ASD that is consistently associated with abnormal patterns of neural activity in the semantic network.

Titre : Brain activity during facial processing in autism spectrum disorder: an activation likelihood estimation (ALE) meta-analysis of neuroimaging studies Type de document : Texte imprimé et/ou numérique Auteurs : Cristiano COSTA, Auteur ; I. A. CRISTEA, Auteur ; E. DAL BÒ, Auteur ; C. MELLONI, Auteur ; C.

Therefore, we conducted an activation likelihood estimation (ALE) meta-analysis of studies examining brain activity during face processing. METHODS: We searched PubMed and PsycINFO using combinations of terms as 'fMRI', 'Autism Spectrum Disorder', 'Face Perception'. Eligible studies reported on DSM-diagnosed ASD individuals, compared to controls (HC), using face stimuli presented in fMRI and reporting whole-brain analysis coordinates. We compared two approaches: 'convergence of differences' (primary analysis) using study-level coordinates from ASD vs. HC contrasts, and 'differences in convergence' (secondary) pooling coordinates within each group separately, and contrasting the resultant ALE maps. RESULTS: Thirty-five studies (655 ASD and 668 HC) were included. Primary analysis identified a cluster in amygdala/parahippocampus where HC showed greater convergence of activation. Secondary analysis yielded no significant results. CONCLUSIONS: Results suggest that ASD dysfunction in face processing relies on structures involved in emotional processing rather than perception. We also demonstrate that the two ALE methodologies lead to divergent results.
