Thought control

Morris Gallo

An article in the December 7 Computerworld titled “Monkey Think, Robot
Do” describes how researchers at Duke University have implanted
electrodes into the brains of trained Owl Monkeys, and used their brain
waves to control a robot arm. Brain waves were picked up by as many as
96 hair thin electrodes, processed by a computer using custom
algorithms, and the processed control signals transmitted to a robot
arm. The trained monkeys were able to manipulate the arm using thought
control. They initially trained rats to control a robot arm using
nothing other then brain waves. During these experiments the scientist
have not only been able to harness the electrical energy of the thought
process but they have learned much of the basic science of the brain.
The article mentions the use of this process to control a prosthesis.
Imagine using either internal or external electrodes to monitor your
thoughts, have this information transmitted to a small processor that
would then control your prosthesis. This would make myoelectrics
obsolete as well as the “advanced” computer-controlled lower limb
prosthesis now on the market.
