Summary
Children with autism spectrum disorder (ASD) and sensory processing dysfunction (SPD) show distinct brain connectivity patterns. These neural synchrony differences may help identify biomarkers for both conditions.
Area of Science:
- Neuroscience
- Developmental Neuroscience
Background:
- Sensory processing dysfunction (SPD) affects individuals with autism spectrum disorder (ASD) and others without ASD.
- The link between sensory dysfunction and resting-state brain activity is not well understood.
Approach:
- Compared long-range resting-state functional connectivity in children aged 8-12 years using magnetoencephalography (MEG).
- Analyzed neural oscillatory behavior in alpha and beta frequency bands.
- Examined group differences between ASD, SPD, and typically developing control (TDC) participants.
Key Points:
- Distinct functional connectivity patterns were observed between ASD and SPD groups in the beta band, but not the alpha band.
- Both ASD and SPD groups differed from the TDC group in both alpha and beta bands.
- Somatosensory cortical beta-band connectivity correlated with tactile processing, and auditory cortical alpha-band connectivity correlated with auditory processing.
Conclusions:
- Findings reveal distinct long-range neural synchrony alterations in SPD and ASD.
- Neural synchrony measures show potential as sensitive biomarkers for ASD and SPD.
