Atypical Neural Activity in Males But Not Females with Autism Spectrum Disorder / Melissa KIRKOVSKI in Journal of Autism and Developmental Disorders, 46-3 (March 2016)
[article]
Titre : Atypical Neural Activity in Males But Not Females with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Melissa KIRKOVSKI, Auteur ; Peter G. ENTICOTT, Auteur ; Matthew E. HUGHES, Auteur ; Susan L. ROSSELL, Auteur ; Paul B. FITZGERALD, Auteur Article en page(s) : p.954-963 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Theory of mind Mentalizing network Sex differences Medial prefrontal cortex Temporo-parietal junction Superior temporal sulcus Functional magnetic resonance imaging Index. décimale : PER Périodiques Résumé : The medial prefrontal cortex (mPFC) and the right temporo-parietal junction (rTPj) are highly involved in social understanding, a core area of impairment in autism spectrum disorder (ASD). We used fMRI to investigate sex differences in the neural correlates of social understanding in 27 high-functioning adults with ASD and 23 matched controls. There were no differences in neural activity in the mPFC or rTPj between groups during social processing. Whole brain analysis revealed decreased activity in the posterior superior temporal sulcus in males with ASD compared to control males while processing social information. This pattern was not observed in the female sub-sample. The current study indicates that sex mediates the neurobiology of ASD, particularly with respect to processing social information.

Titre : Voice identity processing in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Stefanie SCHELINSKI, Auteur ; Claudia ROSWANDOWITZ, Auteur ; Katharina VON KRIEGSTEIN, Auteur Article en page(s) : p.155-168 Langues : Anglais (eng) Mots-clés : autism spectrum disorder voice recognition pitch discrimination famous voice recognition timbre discrimination face recognition superior temporal sulcus Index. décimale : PER Périodiques Résumé : People with autism spectrum disorder (ASD) have difficulties in identifying another person by face and voice. This might contribute considerably to the development of social cognition and interaction difficulties. The characteristics of the voice recognition deficit in ASD are unknown. Here, we used a comprehensive behavioral test battery to systematically investigate voice processing in high-functioning ASD (n?=?16) and typically developed pair-wise matched controls (n?=?16). The ASD group had particular difficulties with discriminating, learning, and recognizing unfamiliar voices, while recognizing famous voices was relatively intact. Tests on acoustic processing abilities showed that the ASD group had a specific deficit in vocal pitch perception that was dissociable from otherwise intact acoustic processing (i.e., musical pitch, musical, and vocal timbre perception). Our results allow a characterization of the voice recognition deficit in ASD: The findings indicate that in high-functioning ASD, the difficulty to recognize voices is particularly pronounced for learning novel voices and the recognition of unfamiliar peoples’ voices. This pattern might be indicative of difficulties with integrating the acoustic characteristics of the voice into a coherent percept—a function that has been previously associated with voice-selective regions in the posterior superior temporal sulcus/gyrus of the human brain.
