This reminds me of an experiment where they put an implant in monkeys&#x27; brains that allowed them to control a robotic arm: <a href="http:&#x2F;&#x2F;www.nytimes.com&#x2F;2008&#x2F;05&#x2F;29&#x2F;science&#x2F;29brain.html?_r=1" rel="nofollow">http:&#x2F;&#x2F;www.nytimes.com&#x2F;2008&#x2F;05&#x2F;29&#x2F;science&#x2F;29brain.html?_r=1</a>.<p>That article doesn&#x27;t mention it, but another article I read at the time (or maybe it was for a followup experiment?) pointed out that while at first the monkeys were moving their own arm in tandem with the robotic arm, eventually they learned to control the robot arm independently of their own arm.<p>That was the most interesting part to me, because it raises the possibility of someday having something like a Dr. Octopus suit.
