Defense Advanced Research Projects Agency (DARPA) is undergoing research to develop a helmet that could control the minds of soldiers through the use of TPU. It would have the potential to control a soldier’s stress and anxiety levels with the click of a remote controlled button. Sound waves would target specific areas of the brain to stimulate activity in regions only a few cubic millimeters in size. This would allow them to target very specific areas of the brain with great accuracy and without inflicting damage to its surroundings. A prototype of this device is currently being worked upon to better the ability and potential of soldiers.
(Inverse) Facebook has some big plans for the future of social networking. A series of job postings discovered Thursday suggest the company wants to use non-invasive techniques to measure user’s’ brain waves, with artificial intelligence decoding the data. The listings are all for the company’s Building 8 lab, a secretive organization headed by the former head of the Defense Advanced Research Projects Agency (DARPA).
One listing seeks a brain-computer interface engineer for a two-year project in the lab focused on advanced brain technologies. The candidate will be responsible for the “application of machine learning methods, including encoding and decoding models, to neuroimaging and electrophysiological data.” In other words, Facebook wants to apply artificial intelligence to brain scan data.
Another listing, for a neural imaging engineer, sheds some light on how Facebook might actually scan people’s brains. The company wants someone to design methods based around “optical, RF, ultrasound, or other entirely non-invasive approaches.”
