The monkeys were coaxed into moving the robot arm to reach and grab a ball, incentivized with sips of sweet juice as a reward.The robot prosthetic isn't directly connected to the monkey (a la Silicon Valley), but instead is linked to the computer that processes signals from the electrodes.

But for the neurons on the same side of the amputated limb, the behavior was reversed.

The connections between neurons started off strong, and were pruned over time to build a new, dense network of cells for muscular control. Karthikeyan Balasubramanian, who led the study and is postdoctoral researcher at the University of Chicago, said the strength of the connections “were shedding off as the animal was trying to learn a new task, because there is already a network controlling some other behavior.

The Plymouth experiment was part of the Vivaria Project, which plans to install computers in zoos across Europe to study differences between animal and artificial life.

Phillips said the experiment showed that monkeys "are not random generators.

That's how we can begin to create truly responsive neuroprosthetic limbs, when people can both move it and get natural sensations through the brain machine interface," he added.

The researchers hope that this will one day be applicable to humans.But after a few days it started rebuilding into a new network that can control both the intact limb and the neuroprosthetic." Nicho Hatsopoulos, co-author of the study and a professor of organismal biology at the University of Chicago said that the study shows long-term amputees can learn to control robotic limbs."[What’s] interesting was the brain's plasticity over long-term exposure, and seeing what happened to the connectivity of the network as they learned to control the device.The £2,000 was spent on setting up a radio link to live stream the activities in the enclosure.“Compared to the cost of reality TV, this was a tiny pinch of money,” Phillips said.“It provided very stimulating and fascinating viewing.”Ultimately the monkeys may have fallen prey to the distractions which curse many novelists.In their case, it was climbing frames, ropes and toys.The (albeit tongue-in-cheek) experiment was to test the old saw : If you gave an infinite number of monkeys an infinite number of typewriters, would they eventually produce the complete works of Shakespeare?After six months, the monkeys failed to produce a single word of English, broken the computer and used the keyboard as a lavatory.Electrodes were implanted to the monkey’s heads in the area where the primary motor cortex is located - an area of the brain that controls movement - and then to the severed limb.For two of the animals, the electrodes were placed on the opposite side to the amputated arm, and for the other monkey the electrode was on the same side as the injury.In fairness to the Paignton six, the letters A, J, L, and M crept in later.Phillips denied the project was a disaster and told the BBC they had learned “an awful lot”.
