Outline of Final Research Achievements

The aim of this research is to investigate a novel sprout model that "atypicality of auditory information processing affects development". We researched on children with autism with ADHD symptoms. The synchronicity of the auditory evoked responses (P1m) in left and right hemispheres induced by speech stimulation was measured with an child-sized MEG system. We investigated the relationship between this brain functional synchronicity and the behavioral ability to be kept still. In children who cannot stay still, it was found that the synchronicity of the P1m in left and right hemispheres are low. This study revealed that the characteristics of auditory information processing are related to ADHD-like symptoms.
