Neuroscientist Nicho Hatsopoulous and his team taught monkeys that lost limbs through accidents how to control a robotic arm. The work has profound implications on what they call the brain-machine interface.

“That's the novel aspect to this study, seeing that chronic, long-term amputees can learn to control a robotic limb,” said Nicho Hatsopoulos, PhD, professor of organismal biology and anatomy at UChicago and senior author of the study. “But what was also 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.”
Here's the basic setup in a similar lab with non-amputee monkeys. The monkey gets juice or some other treat for successfully completing the tasks.
Here's a detailed lecture on the current work in the field:

NASA’s Juno spacecraft took this glamour shot of Jupiter on October 29, 2018, from about 4,400 miles (7,000) kilometers above the planet’s clouds. From NASA: A multitude of magnificent, swirling clouds in Jupiter’s dynamic North North Temperate Belt is captured in this image… Appearing in the scene are several bright-white “pop-up” clouds as well as […]
