Christine M. Falter-Wagner; Christian M. Kiefer; Anthony J. Bailey; Kai Vogeley; Jürgen Dammers – Journal of Autism and Developmental Disorders, 2024
Visual information is organised according to visual grouping principles. In visual grouping tasks individuals with ASD have shown equivocal performance. We explored neural correlates of Gestalt grouping in individuals with and without ASD. Neuromagnetic activity of individuals with (15) and without (18) ASD was compared during a visual grouping…

Papri Saha – Journal of Autism and Developmental Disorders, 2024
With the budding interests of structural and functional network characteristics as potential parameters for abnormal brains, an essential and thus simpler representation and evaluations have become necessary. Eigenvector centrality measure of functional magnetic resonance imaging ("fMRI") offer region wise network representations through…

Provided the significant overlap in features of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD), there is a critical need to identify transdiagnostic markers that could meaningfully stratify subgroups. The objective of this study was to compare the visual evoked potential (VEP) between 30 autistic children, 17…

Barik, Kasturi; Watanabe, Katsumi; Bhattacharya, Joydeep; Saha, Goutam – Journal of Autism and Developmental Disorders, 2023
In this study, we aimed to find biomarkers of autism in young children. We recorded magnetoencephalography (MEG) in thirty children (4-7 years) with autism and thirty age, gender-matched controls while they were watching cartoons. We focused on characterizing neural oscillations by amplitude (power spectral density, PSD) and phase (preferred phase…

Schütz, Magdalena; Boxhoorn, Sara; Mühlherr, Andreas M.; Mössinger, Hannah; Freitag, Christine M.; Luckhardt, Christina – Journal of Autism and Developmental Disorders, 2023
The ability to infer intentions from observed behavior and predict actions based on this inference, known as intention attribution (IA), has been hypothesized to be impaired in individuals with autism spectrum disorder (ASD). The underlying neural processes, however, have not been conclusively determined. The aim of this study was to examine the…

Knudsen, Laust V.; Sheldrick, Abigail J.; Vafaee, Manouchehr S.; Michel, Tanja Maria – Autism: The International Journal of Research and Practice, 2023
Cognition and brain homeostasis depends on cerebral blood flow to secure adequate oxygen and nutrient distribution to the brain tissue. Altered cerebral blood flow has previously been reported in individuals diagnosed with autism spectrum condition in comparison to non-autistics. This phenomenon might suggest cerebral blood flow as a potential…

Describing neural connectivity between pre-frontal and parietal brain regions and anxiety in children and adolescents with Autism Spectrum Disorder (ASD) has the potential to inform diagnosis and treatment decisions. This study aimed to identify the neural connectivity patterns between the prefrontal cortex (PFC) and parietal regions in young…

This study characterizes the subcortical auditory brainstem response (speech-ABR) and cortical auditory processing (P1 and Mismatch Negativity; MMN) to speech sounds and their relationship to autistic traits and sensory features within the same group of autistic children (n = 10) matched on age and non-verbal IQ to their typically developing (TD)…

Yu, Luodi; Huang, Dan; Wang, Suiping; Zhang, Yang – Journal of Autism and Developmental Disorders, 2023
Children with autism often show atypical brain lateralization for speech and language processing, however, it is unclear what linguistic component contributes to this phenomenon. Here we measured event-related potential (ERP) responses in 21 school-age autistic children and 25 age-matched neurotypical (NT) peers during listening to word-level…

Kimaya Sarmukadam; Vicki Bitsika; Christopher F. Sharpley; Mary M. E. McMillan; Linda L. Agnew – Journal of Developmental and Physical Disabilities, 2022
Several lines of research suggest that autism is a neurological phenomenon, but the precise associations between neurological activity and the key diagnostic symptoms of autism are yet to be completely clarified. This study examined EEG connectivity and Sensory Features (SF) in a sample of young autistic males by examining bi-directional neural…

Bathelt, Joe; Koolschijn, P Cédric M. P.; Geurts, Hilde M. – Autism: The International Journal of Research and Practice, 2022
Face recognition is a fundamental function that requires holistic processing. Differences in face processing have been consistently identified in autistic children, but it is unknown whether these differences persist across the adult lifespan. Using event-related functional magnetic resonance imaging, we measured holistic face processing with a…
