CBS News have produced a 12 minute segment of their '60 minutes' documentary, which takes a look in depth at the development of BrainGate and other direct-implantation Brain-Computer Interfaces, or BMI.

They take the human angle, looking at how such connections have changed lives, before moving into the basics of technical specifics, enough that the documentary serves as a base-level, rounded introduction to this new interface paradigm.
