| Research Abstract |
Although cross-modal integration(e. g. visual and tactile sensations) plays is important for adaptation to different environmental conditions, it remains unclear whether or how visual input affects learning of cross-modal integration. To explore this issue I operated intensity of pain by visual information. Forty subjects initially acquired the newly formed visual-tactile integration by using the rubber hand illusion paradigm(Botvinick & Cohen, 1998) to provide false visuospatial perception. Fifteen minutes later, I measured visuospatial false perception and habituation as represented by the skin conductance response. The intensity of pain perception was varied by intensity of visual information. Here I show that visual input affects the learning of visuo-tactile integration and pain perception. Furthermore, I made a tactile stimuli device of compressed-air operated pump to use functional magnetic resonance imaging, and I started the experiment. This study should be contributed to exclude the pain perception mechanism.
