Abstract
[Purpose] In order to elucidate the brain mechanisms for visual perception on Autism spectrum disorders (ASD), we basically observed brain activities of neurotypical subjects with magnetic encephalography (MEG) during a visual task. [Methods] The visual task required the subjects (n=3) to shift their attention via eye movements to a target mark randomly displayed on the right or left side of the screen. The cue images included human side gaze images (gaze condition) or arrow images (arrow condition). We averaged -100-700 ms of MEG data for each condition and performed the analysis of source current presumption by MSP with SPM12. [Results] We observed considerable brain activity for 160-200 ms after displaying visual cues; this activity may be a M170 response, which relates to face and gaze perceptions. These activities were observed on the fusiform face area and superior temporal sulcus. [Conclusion] Our visual task presumably detected the subjects’ brain activities that relate to perception of gaze direction.
