The first direct brain-machine interface, developed in the 1990s, connected a computer to a rat. By 2003, scientists had mostly replaced rats with nonhuman primates. One of which is Jianhui, an eight-year-old rhesus macaque at Zhejiang University in eastern China.
Electrodes implanted in his motor cortex intercept electrical pulses fired from approximately 70 neurons. A computer interprets those signals and sends commands to motors in each finger of the robotic hand. When Jianhui completes a task, such as grasping onto an extended handle, he receives a sip of water from a tube. The imposing device in which he sits keeps his head immobilized during the experiment. Training sessions last for two hours, five days a week. Jianhui has recently mastered grasping, so researchers will now begin teaching him to use all of the fingers on the robot hand in a single, coordinated motion.

What a horrible picture!
Take it down!
I agree, terrible picture. I don't think that monkey would be enjoying that.

Do you enjoy steak occasionally?
How is picture horrible? Grow up people. It doesn't look like it's angry or scared to me, it's not being tortured, and if it was fighting to get out, they would take it out.
Not all scientists are heartless turds like so many of you are completely convinced of. I'm sure they take very good care of that monkey for the time they need him/her.
@DirtySquirties - China's not known for being conscious morally. Maybe looks deceive, but it is disturbing to me.
As a paraplegic of 11 years, I am eagerly anticipating this type of technology being advanced to the next stage of using human subjects. I would love to volunteer to be able to "think" my legs to function again using a computer and external stimuli.
God bless the researchers and the animals they use.

When will DNA paternity tests become 100% accurate?
The scientist now-a-days do not harm the animals and carry on with their research on them..So one cannot think that this is a horrible case!!

Poor monkey, did they paralyze this critter in the lab so out of pity gave it a robotic arm?
But great scientific and medical implications.
