[Cyborg] rat brain robots

Kevin Warwick gave a talk at CMU just a few weeks ago in which he
talked about this and some other research. The wiring of neurons to
electrode arrays is VERY cool, and very promising, but I'm really
unconvinced about the so-called "learning" of his robots.

He also talked at-length about getting an electrode array implanted
into some nerves in his arm. Using this to output signals from his
body to the computer is very impressive. However, as far as the things
he did to input signals from computer to brain, these seemed like they
could all be done using non-invasive displays, (i.e. haptics). I feel
in a certain sense this obsession with direct electrical stimulation
of nerves has held back sensory extension technology by being
expensive and dangerous, but in terms of bandwith per square cm it's
pretty unbeatable!
