Attenuation of sensory processing in the primary somatosensory cortex during rubber hand illusion

Abstract The neural representation of the body is easily altered by integration multiple sensory signals in brain. “rubber hand illusion” (RHI) one most popular experimental paradigms to investigate this phenomenon. During illusion, a feeling ownership rubber created. Some studies have shown that somatosensory processing brain attenuated when RHI occurs. However, it unknown where attenuation Here, we show primary cortex. We found earliest response evoked potentials, which thought originate from cortex, was during RHI. Furthermore, observed before occurrence illusion. Our results suggest cortex factors influencing
