Monkey uses its mind to control another primate, in tests scientists hope could help paralysed people  - Scientists have developed a way for monkeys to control “avatars” that could be used to help paralysed people move their bodies. In the tests scientists found that brain signals from the master monkey’s mind could be used to stimulate an avatar’s spinal cord to control its movements. The findings published in the Natural Communications journal have been called a “key step forward” and could help people who have damaged their spinal cord to the extent that its stops information flowing from the brain to the body. People with such damage are often left unable to walk or feed themselves, and researchers say that even the smallest amount of movement could dramatically improve a person’s life, the BBC reported. The scientists from Harvard Medical School in the US envisage their findings could go towards creating machinery to help patients. As researchers said they could not justify paralysing a monkey for the study, they used a conscious monkey with an implanted brain chip, and an unconscious avatar to be controlled. During the experiment, the conscious monkey’s movements were mapped according to patterns of electrical activity in its neurons. The scientists then hooked the avatar’s spinal cord up to 36 electrodes to measure how it moved according to different combinations of stimulation. In a different test, as the sedated monkey held a joystick, the master thought about moving a cursor up and down. In 98 per cent of tests, the master could correctly control the avatar’s arm.
