| Outline of Final Research Achievements |
The activity of the primary somatosensory cortex plays a vital role in enhancing tactile perceptual performance. In this study, we first evaluated how the activity of primary somatosensory cortex is influenced by improving the tactile perceptual performance using peripheral electrical stimulation. Second, we confirmed what kind of transcranial electrical stimulation modulates the activity of the primary somatosensory cortex and eventually the tactile perceptual performance. Consequently, we observed that decreased activity of inhibitory circuits in the primary somatosensory cortex correlated with improved tactile perceptual performance. Furthermore, transcranial pulsed current stimulation and of the primary somatosensory cortex decreased the activity of inhibitory circuits in the primary somatosensory cortex and transcranial random noise stimulation increased the activity of the primary somatosensory cortex, thus improving the tactile perceptual performance.
