Connecting the human brain to a computer has the potential to help paralyzed and immobilized individuals to control external devices, such as a robotic arm. Brain-computer interfaces have provided control of a single prosthetic arm but never two arms at the same time.

By recording and decoding the activity of sets of almost 500 brain cells in two monkeys, researchers were able to develo...
