Titre : Auditory processing in noise is associated with complex patterns of disrupted functional connectivity in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Fahimeh MAMASHLI, Auteur ; Sheraz KHAN, Auteur ; Hari BHARADWAJ, Auteur ; Konstantinos MICHMIZOS, Auteur ; Santosh GANESAN, Auteur ; Keri-Lee A. GAREL, Auteur ; Javeria ALI HASHMI, Auteur ; Martha R. HERBERT, Auteur ; Matti HÄMÄLÄINEN, Auteur ; Tal KENET, Auteur Article en page(s) : p.631-647 Langues : Anglais (eng) Mots-clés : autism MEG auditory noise connectivity feedback top-down Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is associated with difficulty in processing speech in a noisy background, but the neural mechanisms that underlie this deficit have not been mapped. To address this question, we used magnetoencephalography to compare the cortical responses between ASD and typically developing (TD) individuals to a passive mismatch paradigm. We repeated the paradigm twice, once in a quiet background, and once in the presence of background noise. We focused on both the evoked mismatch field (MMF) response in temporal and frontal cortical locations, and functional connectivity with spectral specificity between those locations. In the quiet condition, we found common neural sources of the MMF response in both groups, in the right temporal gyrus and inferior frontal gyrus (IFG). In the noise condition, the MMF response in the right IFG was preserved in the TD group, but reduced relative to the quiet condition in ASD group. The MMF response in the right IFG also correlated with severity of ASD. Moreover, in noise, we found significantly reduced normalized coherence (deviant normalized by standard) in ASD relative to TD, in the beta band (14–25 Hz), between left temporal and left inferior frontal sub-regions. However, unnormalized coherence (coherence during deviant or standard) was significantly increased in ASD relative to TD, in multiple frequency bands. Our findings suggest increased recruitment of neural resources in ASD irrespective of the task difficulty, alongside a reduction in top-down modulations, usually mediated by the beta band, needed to mitigate the impact of noise on auditory processing.

Titre : Considerations of the built environment for autistic individuals: A review of the literature Type de document : Texte imprimé et/ou numérique Auteurs : Melissa Heather BLACK, Auteur ; Sarah MCGARRY, Auteur ; Lynn CHURCHILL, Auteur ; Emily D'ARCY, Auteur ; Julia DALGLEISH, Auteur ; Isabelle NASH, Auteur ; Alisala JONES, Auteur ; Tin Yan TSE, Auteur ; Jane GIBSON, Auteur ; Sven BÖLTE, Auteur Article en page(s) : p.1904-1915 Langues : Anglais (eng) Mots-clés : Humans Autistic Disorder Autism Spectrum Disorder Built Environment Noise architecture design interior sensory space Index. décimale : PER Périodiques Résumé : Factors related to the interiors of buildings, including the layout of rooms, colours, smells, noises, temperature, ventilation, colour and clutter, among other things, can change the way we interact with our environment and the people around us. Autistic individuals can have differences in processing sensory information and may find aspects of the built environment (BE) over-whelming and difficult to navigate. We reviewed the existing literature exploring the BE and autism. This study found that it is possible to make changes to the BE to create more inclusive and friendly environments for everyone, including autistic individuals. Findings from this study provide clear recommendations that can be used by interior designers, architects, builders, and clinical practitioners to make a positive difference. Key recommendations include using simple spatial layouts, compartmentalising and zoning spaces into specific activity sections and providing retreat spaces. The thoughtful placement of windows and blinds and the installation of dimmable lights, for example, will allow users to manage or reduce sensory over-stimulation caused by lights. Similarly, we recommend creating soundproofing and sound absorbent materials to reduce background noise and sound levels. We also recommend using neutral or simple colour palettes and restrained use of patterns. Finally, and most importantly, the BE needs to be flexible and adaptable to meet the unique needs of each person. This study provides a starting point for design guidelines and recommendations towards making a difference to the everyday experiences of the interiors of buildings.
