Thirty autistic individuals and 30 NT underwent an EEG recording while watching short videos depicting goal-oriented action filmed from a fixed position, zooming in on the scene, and approaching the scene by means of a steadycam. Then, participants underwent a rating task to evaluate their subjective viewing experience. We found that steadycam videos elicited enhanced event-related desynchronization (ERD), suggestive of enhanced neural activity, in the NT group, and a reduced ERD in the autistic group, compared to the other filming conditions. Autistic participants also showed difficulties in returning to baseline mu-power levels after watching videos filmed from a fixed position. Finally, NT reported feeling more comfortable watching videos with movement, whereas autistic participants did not exhibit differences between conditions. We speculated that static, less naturalistic stimuli might impose higher and prolonged cognitive demands on autistic individuals. Understanding these differences might help develop tailored interventions to support perceptual, cognitive, and social processes of autistic people.

Sleep Spindle Abnormalities in Preschool Children With Autism Spectrum Disability: Insights From Nap Polysomnography / Sasha D’AMBROSIO in Autism Research, 18-9 (September 2025)  

Public ISBD [article]  inAutism Research > 18-9 (September 2025) . - p.1764-1774 Titre : Sleep Spindle Abnormalities in Preschool Children With Autism Spectrum Disability: Insights From Nap Polysomnography Type de document : texte imprimé Auteurs : Sasha D’AMBROSIO, Auteur ; Daniele GUALANDRIS, Auteur ; Davide CAPUTO, Auteur ; Francesco DONATI, Auteur ; Ahmad MAYELI, Auteur ; Renata DEL GIUDICE, Auteur ; Fabio FERRARELLI, Auteur ; Alessia MINGARELLI, Auteur ; Federico RAVIGLIONE, Auteur ; Maria Paola CANEVINI, Auteur ; Armando D’AGOSTINO, Auteur Article en page(s) : p.1764-1774 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : ABSTRACT Sigma power and sleep spindles are key elements of Non-Rapid Eye Movement (NREM) sleep. They reflect anatomical and physiological properties of brain circuits, are linked with various behavioral outcomes in typically development (TD) children, and undergo significant modifications during development. Furthermore, recent studies have highlighted the potential of NREM sigma power and sleep spindles as early neurophysiological markers for autism spectrum disability (ASD). Here, we conducted polysomnography (PSG)/EEG recordings during afternoon naps on 50 children aged between 2 and 6 years, diagnosed with ASD or TD. EEG recordings from 19 scalp leads were analyzed, focusing on sigma power and sleep spindle parameters. EEG analyses revealed significant differences in power spectral density between ASD and TD children, particularly in the sigma band and adjacent alpha and beta bands, with increased power localized to anterior EEG leads in ASD children. Higher spindle amplitude and integrated spindle activity (ISA) were found in the ASD group, especially in frontal regions. Additional frequency-specific analyses (10 12 Hz, 12 14 Hz, 14 16 Hz) confirmed significant differences in spindle amplitude and distribution patterns, emphasizing the role of brain regions that are detectable from anterior EEG leads in ASD-related sleep abnormalities. No significant differences were found in spindle density, duration, or frequency outside specific clusters. These findings indicate that some sleep spindle parameters, particularly in frontal areas, are altered in ASD. The study highlights the feasibility of using afternoon nap PSG as a practical and effective method to detect these abnormalities in clinical settings. Future research should investigate the developmental trajectory of spindles in ASD and their potential role as neurophysiological biomarkers, offering valuable insights for diagnosis and prognosis.
