Visually Induced Analgesia: Seeing the Body Reduces Pain (http://www.jneurosci.org/cgi/content/abstract/29/39/12125)
Given previous reports of strong interactions between vision and somatic senses, we investigated whether vision of the body modulates pain perception. Participants looked into a mirror aligned with their body midline at either the reflection of their own left hand (creating the illusion that they were looking directly at their own right hand) or the reflection of a neutral object. We induced pain using an infrared laser and recorded nociceptive laser-evoked potentials (LEPs). We also collected subjective ratings of pain intensity and unpleasantness. Vision of the body produced clear analgesic effects on both subjective ratings of pain and the N2/P2 complex of LEPs. Similar results were found during direct vision of the hand, without the mirror. Furthermore, these effects were specific to vision of one's own hand and were absent when viewing another person's hand. These results demonstrate a novel analgesic effect of non-informative vision of the body.
Here are exciting blogposts related to the topic (more exciting than I can write right now) all with extensive links, some of which lead to Moseley:
Neurocritic: "It hurts less when I can see it" (http://neurocritic.blogspot.com/2009/10/it-hurts-less-when-i-can-see-it.html) (maybe because one can see that it isn't bleeding?)

I think the whole point here is that kinesthetic and visual processing are very, very overlapped. We can use that. The future of all this may make us go extinct if we don't.
