Two monkeys have lately given new meaning to brain power — they used their thoughts to move a wheelchair, driving it forward in pursuit of fresh grapes.

The eye-popping occurrence wasn't telekinesis in action. Rather, scientists at Duke Health used the electrical signals firing inside a monkey's brain to direct the wheelchair's movement. They envision that similar technology someday could be used to help people with severe paralysis, such as quadriplegics or those with Amyotrophic Lateral Sclerosis, better known as Lou Gehrig's Disease.
