Definitely not the first attempt by DARPA researchers to construct a brain-machine interface, although efforts in the past certainly were limited in functionality. As for the latest Neural Engineering System Design (NESD) research program, it intends to increase brain neuron interaction from tens of thousands to touch the figure of millions at any one time.
The future will see DARPA develop a chip that is smaller than one cubic centimeter, and this chip will be implanted within the brain in order to function as a neural interface. What are some of the practical applications that follow? The ability to improve a wearer’s hearing or vision through the feeding of external digital auditory or visual information into the brain. Who doesn’t like a dose of cyborg soldiers in their army anyway?
