Nascent Transhuman
Ahah, thanks for reminding me about the other Big Deal study on this topic, which demonstrated that primates - not even humans, monkeys! - already have the necessary degree of neuroplasticity to directly accept arbitrary extra limbs.I mean, I'm guessing that they could eventually find some way to create a machine mind with enough cognitive plasticity (or whatever you would need) to adapt to non-human bodies or senses (like extra arms or the ability see in ultraviolet or whatever), but I would think that would involve a lot of trial and (probably pretty unpleasant) error. Even if they found a way to make it work, there could be side effects for the successes. Like, maybe they manage to stop machines from being discomforted when houseed in non-humanoid bodies by 'turning off' the part of the mind that identifies with your body, and, like... sure that would technically achieve the goal, but it sounds like it would make a bunch of new problems.
But maybe not. There was an experiment a few years back that genetically modified mice to have an additional color sensing-cone in their eyes. Baby mice that grew up with the extra colors seemed to handle it just fine. And I think that's kinda neat.
You know the feeling you have when you're using a broom to sweep a floor or cutting up an onion with a knife or drawing with a pencil? How you don't really have to think about moving your fingers individually and you just kind of go "Move the broom there" or "Put a line here" or "Cut this bit" and your body does it? That's the same bit of neurological circuitry that handles driving, jet fighters, and Halo; you don't have to think about "move the stick up" or "wrap fingers around wheel and pull to the right", you just go "park there" or "pull up" or "shoot that" and your brain has incorporated the car or jet fighter or Master Chief simulation into your proprioception. Well, it turns out that that precise system is also flexible enough that you can drop a grid of electrodes into a monkey's brain and hook the electrodes up to a robot arm and the monkeys will immediately begin learning to use that arm. It won't even take them very long to get good enough at it to feed themselves. As far as your brain is concerned, a broom or a car is an extra arm.
Article: Here we describe a system that permits embodied prosthetic control; we show how monkeys (Macaca mulatta) use their motor cortical activity to control a mechanized arm replica in a self-feeding task. In addition to the three dimensions of movement, the subjects' cortical signals also proportionally controlled a gripper on the endof the arm.
