What is Brain Science?

In this three-part series, we discuss nanotechnological devices as a relatively new focus, which includes brain scanning tools, directed energy, trans-cranial magnetic and electrical stimulation, and deep brain stimulation - all of which can be used in military and intelligence operations. What are some of the latest developments in brain science and technology? How might differing values around the world address the development and use of these technologies? What are the relative costs and the burdens or risks associated with these possible values?
