      Well there is the exciting area called optogenetics (https://en.wikipedia.org/wiki/Optogenetics) which basically means using light to control cells for example muscle cells, its akin to fibre optic broadband. These muscle nerves can be described a series of electrical signals that can be converted to movement. This technology is a long way off, but has been demonstrated useful in rats to excite parts of the brain associated with positive reinforcement

      Zach has answered it pretty well – I’ll leave that one to him, I cant add anything of value!
