Do we all synch alike? Brain-body-environment interactions in ASD

Area of Science:

• Neuroscience
• Developmental Psychology
• Autism Spectrum Disorder Research

Background:

• Autism Spectrum Disorder (ASD) is defined by restricted interests, routine rigidity, and atypical social communication.
• Altered neuro-oscillatory activity and peripheral nervous system function are increasingly implicated in ASD pathophysiology.
• Central nervous system (CNS) and autonomic nervous system (ANS) rhythms influence human cognition and behavior.

Purpose of the Study:

• To propose a novel perspective of autism as a disorder of impaired temporal dynamics in brain-body-environment coupling.
• To explore how the failure to synchronize with environmental regularities contributes to ASD symptoms.
• To identify potential novel biomarkers for core ASD deficits.

Main Methods:

• Literature review synthesizing evidence on neuro-oscillatory and autonomic nervous system function in ASD.
• Theoretical framework integrating CNS, ANS, and environmental interactions.
• Analysis of existing findings related to temporal perception and synchronization in ASD.

Main Results:

• Evidence suggests ASD involves a failure of the nervous system to adaptively synchronize with predictable environmental events.
• This impaired synchronization impacts perception and behavior, potentially explaining cognitive rigidity and social interaction deficits.
• The brain-body-environment coupling framework offers a new lens for understanding ASD pathophysiology.

Conclusions:

• Impaired temporal dynamics of brain-body-environment coupling is a potential core mechanism in Autism Spectrum Disorder.
• This perspective highlights the importance of studying the interplay between internal rhythms and external environmental cues in ASD.
• The proposed framework may lead to the development of novel biomarkers for ASD diagnosis and intervention.
