Outline of Final Research Achievements

We aimed to clarify the neural basis of children with Autistic Spectrum Disorder (ASD) about an adaptive locomotion. The adaptive locomotion is the one that the locomotion flexibly changes to visual stimuli in the environment. We used the direction distinguish task, and healthy adults and ASD children participated in the present study. The subjects performed behavioral and electroencephalogram (EEG) experiment. In the behavior experiment, we recorded a button response time and a bar catching distance. In the EEG experiment, an event related potential was analyzed. All subjects reproducibly showed N200 component of event related potential in the parietal cortex, and behavioral data and the latency or amplitude of N200 component revealed correlation. As a N200 component reflects the visual dorsal pathway function which plays an important role in spatial integration, we believe the visual task used in the present study is useful to evaluate the visual dorsal pathway of ASD children.
