Monkey's mind used to control body of 'avatar'

World Bulletin / News Desk

US scientists at Harvard Medical School have used the brain of one monkey to actively control the limbs of another sedated monkey, called an 'avatar'.

The avatar's spinal cord was electrically stimulated by the master monkey's mind, resulting in controlled movement.

Brain scans of the master monkey were taken using a brain chip implanted that could monitor the activity of up to 100 neurons, while the avatar had 36 electrodes implanted in the spinal cord.

A joystick was put in the hands of the sedated avatar, which was then controlled by the mind of the master monkey, with success in 98% of the tests.

Prof Bernard Conway, head of biomedical engineering at the University of Strathclyde, told the BBC: "The work is a key step forward that demonstrates the potential of brain machine interfaces to be used in restoring purposeful movement to people affected by paralysis."

"However, significant work still remains to be done before this technology will be able to be offered to the people who need it," he added.
