DARPA backing cortical modem:

The first Program Manager to present, Phillip Alvelda, opened the event with his mind blowing project to develop a working “cortical modem”. What is a cortical modem you ask? Quite simply it is a direct neural interface that will allow for the visual display of information without the use of glasses or goggles. I was largely at this event to learn about this project and I wasn’t disappointed.

Leveraging the work of Karl Deisseroth in the area of optogenetics, the cortical modem project aims to build a low cost neural interface based display device. The short term goal of the project is the development of a device about the size of two stacked nickels with a cost of goods on the order of $10 which would enable a simple visual display via a direct interface to the visual cortex with the visual fidelity of something like an early LED digital clock.

The implications of this project are astounding.
