The articles I am linking to are of course spinning in the positive.
But, this is DARPA, talking of controlling the human brain.
That which controls every function of your body.
So put aside the fairy tales of wounded soldiers, for their is another agenda at hand.
Controlling the Brain
-The implants would use light pulses to activate certain brain regions and reroute function
-Such brain implants made from electrodes or optical fibers would sit on the brain’s surface and monitor the electrical signals sent among neurons. They would also beam light pulses to stimulate specific parts of the brain
Stimulate them for what exactly? Who would control the 'stimulation'?
"Learning how to manage the human brain has been a top priority for DARPA in recent years"
Pentagon turns to Brain Implants via DARPA
Scientists can create conceptual, mathematical models of brain activity, and are also able to record the electrical pulses emitted by individual neurons in the brain, which offers insight into how those neurons communicate.
But what experts can’t yet do, Shenoy said, is alter those electrical pulses to turn brain circuits on or off. So, what brain circuits is DARPA looking to shut down, alter or bypass?
