Outline of Final Research Achievements |
This study revealed that tactile stimulation induced the degradation of visual perception. Sound was also found to induce the degradation of visual perception in the very similar manner with the tactile case. We also demonstrated that the paired presentation of visual and tactile inputs induced the activations in the somatosensory brain areas and the deactivations in the visual areas. These findings suggests that perceptual processes would be involved in the degradation of visual perception by another modality inputs, and the facilitatory and inhibitory neural responses and interactions could contribute to the phenomena.
