Tought-controlled prosthetic arm is about to change everything

For the current crop of state-of-the-art prosthetic arms,
you have to control the fingers and finer movements with your feet. It
takes a lot of getting used to and is completely unlike using a normal
arm. But a new model purports to be controlled by thoughts, which could
be revolutionary.













It's especially good news for quadriplegics, who don't have the
option of controlling an arm with their feet. That's who will get the
first system, testing the arm's ability to sidestep spinal injuries. It
will be controlled via sensors implanted in the brain, and it'll work
both ways, with sensors in the fingers sending signals back to the
brain. Pretty amazing stuff.

Will it work? We'll see, but I sure hope so. It could be revolutionary.

What if someone has suicidal thoughts?
