Moving a limb by the power of thought alone

The power of thought alone is not enough to move inanimate objects — unless the object is a robotic leg wired to your brain, that is.
A 32-year-old man whose knee and lower leg were amputated in 2009 after a motorcycle accident is apparently the first person with a missing lower limb to control a robotic leg with his mind. A team led by biomedical engineer Levi Hargrove at the Rehabilitation Institute of Chicago in Illinois reported the breakthrough last week in the New England Journal of Medicine1, including a video that shows the man using the bionic leg to walk up stairs and down a ramp, and to kick a football.
Nature is, of course, careful to write up the story so as to avoid any implications of this fact.
