다국어 초록 (Multilingual Abstract)

The purpose of our study is to clarify about the influence that the visual information gives to the brain activities when pressure exerted the abdomen by waist belts. The visual information means that the some different visual information is inputted it, and the brain activity is evaluated by Electroencephalogram(EEG) measurements. At the same time, we carried out the sensory tests and verified about the relations between the psychological stress and the brain activities. There was a difference in change in the power of the α wave with the eyes opened between man and woman. From the result of the sensory test, in the case of under the condition in the darkness with the eyes opened, there was no change in the a wave with before the pressure and after the pressure. In the other cases, α wave changed in the same way with before the pressure and after the pressure. In the case of the visible and the invisible in pressure place, α wave changed in the same way with before the pressure and after the pressure, but there was a difference in value. From the above, it isn``t recognized that the visual information is influencing a pressure sense but some influences are given to it to the brain activities.
