On the Neuroimaging of Autism in the Context of Human Brain Diversity / Josselin HOUENOU in Key Issues in Mental Health, 180 (2015)

Public ISBD [article]  inKey Issues in Mental Health > 180 (2015) . - p.68-79 Titre : On the Neuroimaging of Autism in the Context of Human Brain Diversity Type de document : Texte imprimé et/ou numérique Auteurs : Josselin HOUENOU, Auteur ; Pauline CHASTE, Auteur Article en page(s) : p.68-79 Langues : Anglais (eng) Index. décimale : AUT-B AUT-B - L'Autisme - Ouvrages généraux et scientifiques Résumé : Numerous neuroimaging studies of autism spectrum disorders (ASD) have been conducted. Although many of the results of these studies do not overlap, some evidence has accumulated in support of the existence of some atypical brain morphology and function patterns. Indeed, studies have consistently reported structural abnormalities in the prefronto-striatal networks. Functional neuroimaging studies during social tasks have revealed altered patterns of activation in the fusiform gyrus and the superior temporal sulcus, two regions implicated in face recognition and social processing. Moreover, hypoactivation of the bilateral superior temporal gyri during language processing has also consistently been reported. Brain growth patterns are less clear. However, several studies have shown an atypical pattern, with overgrowth from birth to early infancy followed by a slower rate of growth compared to typically developing children and adults. Lastly, recent neuroimaging techniques such as diffusion tensor imaging and functional MRI connectivity measures have revealed long-range underconnectivity in ASD. Autism has thus been recently conceptualized as a brain connectivity disorder. This approach allows a better understanding of the failure of social and communication abilities in ASD.

Preserved navigation abilities and spatio-temporal memory in individuals with autism spectrum disorder / Nathan NEU ; Aurélie WATILLIAUX ; Axelle MARTINEZ-TERUEL ; Mihoby RAZAFINIMANANA ; Jennifer BOISGONTIER ; Sevan HOTIER ; Marc-Antoine D'ALBIS ; Richard DELORME ; Anouck AMESTOY ; Å tefan HOLIGA ; Myriam Ly-Le MOAL ; Pierrick COUPÃ ; Marion LEBOYER ; Josselin HOUENOU ; Laure RONDI-REIG ; Anne-Lise PARADIS in Autism Research, 16-2 (February 2023)

Beyond its role in hallmark features of ASD, the cerebellum and its connectivity with forebrain structures also play a role in navigation. However, the current understanding of navigation abilities in ASD is equivocal, as is the impact of the disorder on the functional anatomy of the cerebellum. In the present study, we investigated the navigation behavior of a population of ASD and typically developing (TD) adults related to their brain anatomy as assessed by structural and functional MRI at rest. We used the Starmaze task, which permits assessing and distinguishing two complex navigation behaviors, one based on allocentric learning and the other on egocentric learning of a route with multiple decision points. Compared to TD controls, individuals with ASD showed similar exploration, learning, and strategy performance and preference. In addition, there was no difference in the structural or functional anatomy of the cerebellar circuits involved in navigation between the two groups. The findings of our work suggest that navigation abilities, spatio-temporal memory, and their underlying circuits are preserved in individuals with ASD.

Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : BACKGROUND: The cerebellum contains more than 50% of all neurons in the brain and is involved in a broad range of cognitive functions, including social communication and social cognition. Inconsistent atypicalities in the cerebellum have been reported in individuals with autism compared to controls suggesting the limits of categorical case control comparisons. Alternatively, investigating how clinical dimensions are related to neuroanatomical features, in line with the Research Domain Criteria approach, might be more relevant. We hypothesized that the volume of the "cognitive" lobules of the cerebellum would be associated with social difficulties. METHODS: We analyzed structural MRI data from a large pediatric and transdiagnostic sample (Healthy Brain Network). We performed cerebellar parcellation with a well-validated automated segmentation pipeline (CERES). We studied how social communication abilities-assessed with the social component of the Social Responsiveness Scale (SRS)-were associated with the cerebellar structure, using linear mixed models and canonical correlation analysis. RESULTS: In 850 children and teenagers (mean age 10.8?+?3 years; range 5-18 years), we found a significant association between the cerebellum, IQ and social communication performance in our canonical correlation model. LIMITATIONS: Cerebellar parcellation relies on anatomical boundaries, which does not overlap with functional anatomy. The SRS was originally designed to identify social impairments associated with autism spectrum disorders. CONCLUSION: Our results unravel a complex relationship between cerebellar structure, social performance and IQ and provide support for the involvement of the cerebellum in social and cognitive processes.
