Inter-trial coherence of medial frontal theta oscillations linked to differential feedback processing in youth and young adults with autism / Stefon VAN NOORDT in Research in Autism Spectrum Disorders, 37 (May 2017)
[article]
Titre : Inter-trial coherence of medial frontal theta oscillations linked to differential feedback processing in youth and young adults with autism Type de document : Texte imprimé et/ou numérique Auteurs : Stefon VAN NOORDT, Auteur ; Jia WU, Auteur ; Archana VENKATARAMAN, Auteur ; Michael J. LARSON, Auteur ; Mikle SOUTH, Auteur ; Michael J. CROWLEY, Auteur Article en page(s) : p.1-10 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders (ASD) Reward processing Theta oscillations Event-related spectral analysis Inter-trial phase coherence Index. décimale : PER Périodiques Résumé : Impairment in prediction and appreciation for choice outcomes could contribute to several core symptoms of ASD. We examined electroencephalography (EEG) oscillations in 27 youth and young adults diagnosed with autism spectrum disorder (ASD) and 22 IQ-matched neurotypical controls while they performed a chance-based reward prediction task. We re-analyzed our previously published ERP data (Larson et al., 2011) and examined theta band oscillations (4–8 Hz) at frontal midline sites, within a timing window that overlaps with the feedback-related negativity (FRN). We focused on event-related changes after presentation of feedback for reward (WIN) and punitive (LOSE) outcomes, both for spectral power and inter-trial phase coherence. Results In our reward prediction task, for both groups, medial frontal theta power and phase coherence were greater following LOSE compared to WIN feedback. However, compared to controls, inter-trial coherence of medial frontal theta was significantly lower overall (across both feedback types) for individuals with ASD. Our results indicate that while individuals with ASD are sensitive to the valence of reward feedback, comparable to their neurotypical peers, they have reduced synchronization of medial frontal theta activity during feedback processing. This finding is consistent with previous studies showing neural variability in ASD and suggest that the processes underlying decision-making and reinforcement learning may be atypical and less efficient in ASD.

Coherence values for candidate connection regions were calculated from eyes-closed resting EEGs in two independent groups. Hypersynchrony within the right anterior region was related to AQ in both groups (p?0.05), and variability in this hypersynchrony was related to the rs9074 polymorphism in the total group (p?0.05). In conclusion, theta hypersynchrony within the right anterior region during eyes-closed rest can be considered a quantitative measure for autistic traits. Replicating our findings in two independent populations with different backgrounds strengthens the validity of the current study.
