Nonetheless, before being 'social', faces are visual stimuli. The present magnetoencephalography study investigated the time course of brain activity during an implicit emotional task in visual emotion-related regions in 19 adults with ASD (mean age 26.3 +/- 4.4) and 19 typically developed controls (26.4 +/- 4). The results confirmed previously-reported differences between groups in brain responses to emotion and a hypo-activation in the ASD group in the right fusiform gyrus around 150 ms. However, the ASD group also presented early enhanced activity in the occipital region. These results support that impaired face processing in ASD might be sustained by atypical responses in primary visual areas.

Reduced beta connectivity during emotional face processing in adolescents with autism / Rachel C. LEUNG in Molecular Autism, (October 2014)  

Public ISBD [article]  inMolecular Autism > (October 2014) . - p.1-13 Titre : Reduced beta connectivity during emotional face processing in adolescents with autism Type de document : texte imprimé Auteurs : Rachel C. LEUNG, Auteur ; Annette X. YE, Auteur ; Simeon M. WONG, Auteur ; Margot J. TAYLOR, Auteur ; Sam M. DOESBURG, Auteur Article en page(s) : p.1-13 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impairments in social cognition. The biological basis of deficits in social cognition in ASD, and their difficulty in processing emotional face information in particular, remains unclear. Atypical communication within and between brain regions has been reported in ASD. Interregional phase-locking is a neurophysiological mechanism mediating communication among brain areas and is understood to support cognitive functions. In the present study we investigated interregional magnetoencephalographic phase synchronization during the perception of emotional faces in adolescents with ASD.
