The ostensible purpose is to better treat mental illness, but I think we all know what the experimental research wing of the military’s real motives are. As reported by the Boston Globe:
The federal Defense Advanced Research Projects Agency, known as DARPA, announced Thursday that it intended to spend more than $70 million over five years to jump to the next level of brain implants, either by improving deep brain stimulation or by developing new technology.
The new program, called Systems-Based Neurotechnology and Understanding for the Treatment of Neuropsychological Illnesses, is part of an Obama administration brain initiative that is intended to promote innovative basic neuroscience. Participants in the initiative include DARPA, the National Institutes of Health, and the National Science Foundation.
DARPA‘s project is partly inspired by the needs of combat veterans who suffer from mental and physical conditions, and is the first to directly invest in researching human illness as part of the brain initiative.
