Visual analgesia: Seeing the body reduces pain

Visual analgesia: Seeing the body reduces pain : Neurophilosophy: "These phenomena occur because the brain fuses stimuli from different sensory systems to generate a coherent experience of bodily sensations. The precise mechanisms are unknown, and it is also unclear whether these effects depend upon specific visual stimuli. But according to a new study from University College London, the general 'context' of vison is enough to modulate pain. In the current issue of the Journal of Neuroscience, they report that merely looking at one's hand can affect the perception of laser-induced pain, and how it is processed in the cerebral cortex. Together with earlier work, these findings point to a simple method for managing acute pain."
