Joint attention is a social interaction skill that normally develops in infancy and involves following another’s gaze to a stimulus. This skill is absent or developmentally delayed in autism spectrum disorders (ASD), causing cascading effects on development. Neural synchrony in the gamma frequency band is thought to be involved in cognitive functions such as joint attention. The current study investigated differences in gamma power between neurotypicals and ASD as measured by magnetoencephalography (MEG) while performing a gaze cueing task simulating joint attention. Results support lower frontal gamma power in ASD, suggesting that impaired generation of gamma activity in the prefrontal …
