The Daily Mail (UK) reports that “about 2.7 million Americans served in the Iraq and Afghanistan wars, and at least 20 per cent of them have Post Traumatic Stress Disorder (PTSD).”  

“The US Defense Advanced Research Project Agency (Darpa) says it can reduce this number by treating war veterans using chip implants.”  

“Researchers at the organisation say wireless ‘neuroprosthetic’ brain implants will also help restore memory functions and heal traumatic brain injuries.”
