Abstract
In the modern society, many people feel loneliness and uneasiness, dissatisfaction memtally. These accumulations may produce serious social problems such as the suicide. "Iyashi" that is stimulation to restore a state of mind is effective to improve these problems. In this study, I focused on tactile stimulation and measured the brain activity of the "Iyashi" state using fMRI and alanyzed it. In fMRI experiments, "Iyashi" state was reproduced by tactile stimulations and storythinking. The areas activated in "Iyashi" state by tactile stimulation were anterior cingulate cortex and middle frontal gyrus. Anterior cingulate cortex was also activated by storythinking. It was shown that these areas was deeply related to "Iyashi". In addition, I inspected whether could distinguish "Iyasi" state by a brain activation pattern. In the case of only tactile stimulation data, it was succeeded to distinguish significantly. In the case of different input stimulation data, it was not succeeded. It was suggested that processes of "Iyashi" were different.
