POPULAR SCIENCE: DARPA Wants to Install Transcranial Ultrasonic Mind Control Devices in Soldiers’ Helmets. “DARPA has been trying to crawl inside the minds of soldiers for a while now, but a new ultrasound technology could let them get deeper inside than ever. Working under a DARPA grant, a researcher at Arizona State is developing transcranial pulsed ultrasound technology that could be implanted in troops’ battle helmets, allowing soldiers to manipulate brain functions to boost alertness, relieve stress, or even reduce the effects of traumatic brain injury.”
