DARPA, the highly secretive arm of the Department of Defense, have launched various projects that will involve implanting microchips into soldiers’ brains – in an attempt to enhance battlefield performance and repair the traumatized minds of soldiers returning from war. “Of the 2.5 million Americans who served in Iraq and Afghanistan, 300,000 of them came home with traumatic brain injury,” author Annie Jacobsen told NPR. “DARPA initiated a series of programs to help cognitive functioning, to repair some of this damage. And those programs center around putting brain chips inside the tissue of the brain.” Fusion.net reports: In her new book about the history of DARPA, “The Pentagon’s Brain,” Jacobsen writes about DARPA’s “classified brain programs.” Scientists, she says, are already testing “implantable wireless ‘neuroprosthetics’” to help soldiers with brain injuries. “[S]oldiers allow the tiny machines, or chips, to be implanted in their brain,” Jacobsen writes in the book. “Despite multiple appeals through the Office of the Secretary of Defense, DARPA declined to grant me an interview with any of these brain-wounded warriors.” A DARPA spokesperson told Fusion that “brain-neural interfaces” have not been implanted in soldiers, though researchers have already begun testing such devices by temporarily implanting electrical arrays into the brains [...]
