| Outline of Final Research Achievements |
Left-right reversed stereophonic space was achieved in a wearable manner, and adaptation processes during about one-month exposure to this unusual space were examined using magnetoencephalography. The exposure revealed the presence of early adaptation related to perception in which cross-sensory errors are compensated based on a new integration rule, late adaptation related to behavior in which a priority of integration processing is changed, and their intermediate process. Moreover, the early and late adaptations are considered to be reflected in brain rhythms and evoked responses, respectively. Although multisensory information processing has been typically discussed from a viewpoint of additive brain activity that cannot be explained by a summation of unimodal activity, this study revealed the importance of structured brain rhythms with dynamic characteristics in addition to it.
