Longitudinal Heschl's Gyrus Growth During Childhood and Adolescence in Typical Development and Autism / Molly B. D. PRIGGE in Autism Research, 6-2 (April 2013)
[article]
Titre : Longitudinal Heschl's Gyrus Growth During Childhood and Adolescence in Typical Development and Autism Type de document : Texte imprimé et/ou numérique Auteurs : Molly B. D. PRIGGE, Auteur ; Erin D. BIGLER, Auteur ; P. Thomas FLETCHER, Auteur ; Brandon A. ZIELINSKI, Auteur ; Caitlin RAVICHANDRAN, Auteur ; Jeffrey S. ANDERSON, Auteur ; Alyson L.

LAINHART, Auteur Année de publication : 2013 Article en page(s) : p.78-90 Langues : Anglais (eng) Mots-clés : autism Heschl's gyrus longitudinal development MRI Index. décimale : PER Périodiques Résumé : Heightened auditory sensitivity and atypical auditory processing are common in autism. Functional studies suggest abnormal neural response and hemispheric activation to auditory stimuli, yet the neurodevelopment underlying atypical auditory function in autism is unknown. In this study, we model longitudinal volumetric growth of Heschl's gyrus gray matter and white matter during childhood and adolescence in 40 individuals with autism and 17 typically developing participants. Up to three time points of magnetic resonance imaging data, collected on average every 2.5 years, were examined from individuals 3–12 years of age at the time of their first scan. Consistent with previous cross-sectional studies, no group differences were found in Heschl's gyrus gray matter volume or asymmetry. However, reduced longitudinal gray matter volumetric growth was found in the right Heschl's gyrus in autism. Reduced longitudinal white matter growth in the left hemisphere was found in the right-handed autism participants. Atypical Heschl's gyrus white matter volumetric growth was found bilaterally in the autism individuals with a history of delayed onset of spoken language. Heightened auditory sensitivity, obtained from the Sensory Profile, was associated with reduced volumetric gray matter growth in the right hemisphere. Our longitudinal analyses revealed dynamic gray and white matter changes in Heschl's gyrus throughout childhood and adolescence in both typical development and autism.

Despite the emerging understanding that ASD is a developmental disconnection syndrome, very little is known about structural brain networks in preschool-aged children with low-functioning ASD. We aimed to investigate the structural brain connectivity of low-functioning ASD using diffusion magnetic resonance imaging and graph theory to examine alterations in different brain network topologies and identify any correlations with the clinical severity of ASD in preschool-aged children. Fifty-two preschool-aged children (28 with ASD and 24 with typical development) were included in the analysis. Graph-based network analysis was performed to examine the global and local structural brain networks. Nodal network measures exhibited increased nodal strength in the right Heschl's gyrus, which was positively associated with all autistic clinical symptoms (Autism Diagnostic Observation Schedule and Childhood Autism Rating Scale [CARS]). The nodal strength of the right inferior temporal gyrus showed a moderate correlation with the CARS score. Using network-based statistics, we identified a subnetwork with increased connections encompassing the right Heschl's gyrus and the right inferior temporal gyrus in preschool-aged children with ASD. The asymmetric value in the inferior temporal gyrus exhibited right dominance of nodal strength in children with ASD compared to that in typically developing children. Our findings support the theory of aberrant brain growth and overconnectivity as the underlying mechanism of ASD and provides new insights into potential regional biomarkers that can detect low-functioning ASD in preschool-aged children. LAY SUMMARY: This study supports the theory of aberrant brain growth and overconnectivity as an explanation for ASD. Measuring the right HG and inferior temporal gyrus provides new insights of potential regional biomarkers underpinning ASD in preschool-aged children.

Titre : Rightward hemispheric asymmetries in auditory language cortex in children with autistic disorder: an MRI investigation Type de document : Texte imprimé et/ou numérique Auteurs : N. M. GAGE, Auteur ; J. JURANEK, Auteur ; P. A. FILIPEK, Auteur ; K. OSANN, Auteur ; P. FLODMAN, Auteur ; A. L. ISENBERG, Auteur ; M. A. SPENCE, Auteur Article en page(s) : p.205-14 Langues : Anglais (eng) Mots-clés : Auditory cortex Developmental disorder Heschl's gyrus Language cortex Posterior superior temporal gyrus Index. décimale : PER Périodiques Résumé : PURPOSE: determine if language disorder in children with autistic disorder (AD) corresponds to abnormalities in hemispheric asymmetries in auditory language cortex. METHODS: MRI morphometric study in children with AD (n = 50) to assess hemispheric asymmetries in auditory language cortex. A key region of interest was the planum temporale (PT), which is larger in the left hemisphere in most healthy individuals. RESULTS: (i) Heschl's gyrus and planum polare showed typical hemisphere asymmetry patterns; (ii) posterior Superior Temporal Gyrus (pSTG) showed significant rightward asymmetry; and (iii) PT showed a trend for rightward asymmetry that was significant when constrained to right-handed boys (n = 30). For right-handed boys, symmetry indices for pSTG were significantly positively correlated with those for PT. PT asymmetry was age dependent, with greater rightward asymmetry with age. CONCLUSIONS: results provide evidence for rightward asymmetry in auditory association areas (pSTG and PT) known to subserve language processing. Cumulatively, our data provide evidence for a differing maturational path for PT for lower functioning children with AD, with both pre- and post-natal experience likely playing a role in PT asymmetry.
