Imagine mastering instruments, learning to tango and becoming fluent in French — in months, weeks, even days. No, it’s not science fiction: A new program by the government’s Defense Advanced Research Projects Agency aims to tweak your nervous system to make you learn better and faster.

The goal of the new DARPA program, called Targeted Neuroplasticity Training, is to stimulate your peripheral nervous system, the network of nerves on the outside of your brain and spinal cord, to facilitate the development of cognitive skills. If it works, TNT could become a faster and cheaper way to train people on foreign languages, intelligence analysis, cryptography and more.
