- Researchers connected a human to a rat via a computer without the need for brain implants
- Anaesthetised rat hooked up to a device to fire its neurons remotely
- Could be used to teach paralysed patients to use their limbs again
Harvard researchers have completed a bizarre experiment which allows a human volunteer to remotely wag a rat’s tail using just brainwaves.
The unique experiment paves the way for ‘mind control’ systems.
Researchers even hope that a similar system could be used to ‘teach’ paralysed patients to move their limbs again.
HOW IT WORKED
The human volunteers wore electrode caps that monitored their brain activity using electroencephalography (EEG).
Across the lab, an anaesthetised rat was hooked up to a device that made the creature’s neurons fire whenever it delivered an ultrasonic pulse to the rat’s motor cortex
COULD THIS BE USED IN REVERSE TO CONTROL HUMAN SUBJECTS OBVIOUSLY THE ANSWER IS YES.
Using this system, all six of the volunteers were able to trigger movement in the rat’s tail with little difficulty, and the system was 94% accurate.
Professor Yoo says it should be possible for two humans to use a similar system in the foreseeable future.
‘Our results demonstrate the feasibility of a computer-mediated BBI (Brain to Brain interface) that links central neural functions between two biological entities, which may confer unexplored opportunities in the study of neuroscience with potential implications for therapeutic applications,’ the team wrote.
