| Outline of Final Research Achievements |
Previous studies suggest that the primary visual cortex can be activated by touching tactile stimuli while participants are closing their eyes. In this study, we investigated whether the activation in the primary visual cortex induced by tactile stimulation represents tactile stimulus information using neural decoding techniques. Results showed that the primary visual cortex was activated by tactile stimulation even for normal sighted participants but tactile stimulus prediction from the activity in the primary visual cortex was not statistically significant for all participants. These results suggest that the activity in the primary visual cortical evoked by tactile stimulation might not contain tactile stimulus information, at least with regard to types of tactile stimuli used in our experiments.
