The second animal, or 'avatar', was fully sedated in a separate enclosure with its arm strapped to a 360-degree joystick.
This joystick was used to move the cursor, and chase the circular target, on the screen in front of the 'master.'
As the 'master' thought of moving the cursor, its brain signals were decoded to determine which of the two targets it had in mind.
This data was relayed in real-time to the spinal cord of the sleeping avatar, whose arm manipulated the joystick accordingly.
Every time the cursor hit its target, the master received a squirt of juice as reward.
In 98% of tests, the master could correctly control the avatar's arm.
One of the researchers said: "The goal is to take people with brain stem or spinal cord paralysis and bypass the injury.
"The hope is ultimately to get completely natural movement, I think it's theoretically possible, but it will require an exponential additional effort to get to that point."
