We analyzed magnetoencephalography data obtained from 21 healthy elderly subjects (60–75 years old) who had participated in our previous intervention study, which included three types of intervention groups. After cognitive intervention, high-gamma activities (52–100 Hz) were differently altered between groups. Our preliminary results suggest the usefulness of high-gamma activities as an index of the effectiveness of cognitive training in elderly subjects.
