Speaker 0 explains that when you move your arm, your brain sends a signal to your muscles, and there is a nerve near the skin (the ulnar nerve) that innervates three fingers. The idea presented is to stimulate that nerve so that copying your brain signal sent to your hand makes your hand move when your brain tells it to move. In other words, this could cause someone to “take away your free will” and become your agent, removing control over the hand.
The demonstration proceeds with locating the ulnar nerve and connecting it to a human-to-human interface. Sam is asked to squeeze his hand to provide a signal. The setup is described as feeling strange at first, similar to losing free will and having someone else act as your agent, so Sam is asked to relax his hand.
Miguel is invited to participate. Sam squeezes again, and the device is connected so the signal can be simulated in the hand. Miguel is asked if he is ready; he says he is. The device is turned on, and Miguel’s hand begins to move in response to the brain signal. Sam is asked to squeeze again, and the response is repeated with a small, controlled movement.
The presenter then demonstrates that both hands can be controlled: the brain is currently controlling both Miguel’s arm and Sam’s arm. Miguel is asked to relax his hand, and the question is posed: what happens if the presenter takes over control of Miguel’s hand? When Miguel relaxes, nothing happens because the brain must initiate the movement. Miguel then performs the action again, confirming the effect.
The session concludes with gratitude to the participants. The presenter notes that this is happening worldwide in electrophysiology and proclaims a forthcoming “neuro revolution.”
