Lower Cortical Activation and Altered Functional Connectivity Characterize Passive Auditory Spatial Attention in ASD.
Sergio Osorio, Jasmine Tan, Grace Levine and 12 others
PMID 40988632WHAT IT FOUND
Children with ASD showed lower brain activation and different connectivity patterns when hearing sounds change location, even while ignoring them.
These neural differences correlated with autism severity and auditory sensory symptoms, suggesting distinct processing of spatial audio cues.
Key findings
01ASD individuals had significantly lower auditory cortical activation magnitudes during spatial jump trials compared to typically developing peers.
02Alpha-band functional connectivity from the auditory cortex to prefrontal and parietal regions differed between groups, with ASD showing higher connectivity during spatial jumps.
03Connectivity measures in the ASD group correlated with autism severity scores and auditory sensory profile scores.

What it does not show
The sample size was relatively small, which limits the generalizability of the findings. The task was passive, so it is unclear if participants with ASD were attending to the sounds differently than typically developing peers despite instructions to ignore them. The study did not include behavioral measures of auditory spatial attention, so it is unknown if the neural differences translate to observable functional deficits in sound localization.
Declared interests
The authors declare no conflict of interest.
The easy way to misread this
Do not assume these neural differences directly cause specific behavioral deficits in sound localization, as the study did not measure behavioral performance on the auditory task. The findings describe brain activity patterns during passive listening, not active attention or functional outcomes.
