How the Sense of Body Influences the Sense of Touch
How the Sense of Body Influences the Sense of Touch
Vision has an impact on the primary levels of tactile processing, and visual information related to the body appears to be effective in enhancing the tactile sensation. To substantiate this notion, this chapter discusses how visuotactile interactions improve the tactile perception. Visual enhancement of touch and visual remapping of touch are the two types of visuotactile interaction that show modulation of the tactile sensation in the presence of visual information related to the body. Visual information pertaining to the body gets integrated within the somatosensory system to enhance the tactile perception. The response of neurons in the primary somatosensory cortex helps determine tactile sensitivity. In visual enhancement of touch, body space where sensory stimuli are perceived can be determined through body-related visual information. In visual remapping of touch, somatosensory systems are activated through the observation of touch, and perceive tactile stimuli.
