Changes of cerebral activation owing to the difference of qigong sensitivity : Deactivation of the anterior cingulate gyrus in a qigong-sensitive subject(Report by ISLIS President)(Without Peer Review)(The Thirteenth Symposium on Life Information Science)

Abstract

A qigong experiment was conducted on the right laokung of a qigong-sensitive subject and a qigong-insensitive subject. The changes of cerebral activation were examined using f-MRI. As qigong is said to be effective for cerebral relaxation, both the activation and the deactivation of cerebral activities were focused on and comparatively studied. Activation was observed in the first left somatosensory area and the right visual area, while deactivation was seen in the first right motor area and the anterior cingulate gyrus of the qigong-sensitive subject. On the other hand, little activation in the same areas was observed in the qigong-insensitive subject. These results enabled the authors to conjecture that the degree of cerebral activation during qigong depends on the subject's sensitivity and that strong deactivation occurs in the anterior cingulate gyrus, particularly when qigong is effective.
