The Pentagon ’s enquiry arm wants to trick out troops ’ brains , from the country that regulate vigilance and cognition to psychiatrical well - being . And they want to do it all from the outside in , with a gadget installed inside the troops ’ helmet .
“ Remote Control of Brain Activity Using Ultrasound , ” the Defense Department ’s Armed with Science blog promises .
It ’s the late out - there project in the military ’s growing arsenal of brainiac - based research . In late month alone , the Pentagon ’s funded project tooptimize troop ’s minds , prevent injuriesand evenpreemptively assesscognitive ability and exposure to traumatic strain . Now , Darpa ’s fund one lab that ’s trying to do it all – from boosting scout group smartness to preclude traumatic brain injuries .
Arizona State University neuroscientistWilliam Tylerhas been go with funding from the Army Research Laboratory for years . That neurotechnology work has now caught the eye of Darpa , which awarded his lab a Young Faculty Award to improve upon non - invasive approach to brain stimulation .
“ When hoi polloi require what this kind of equipment could do , I ask them what their brain does for them , ” Tyler tells Danger Room . “ The brain process all the functions of your body , and if you knew the neuroanatomy , then you may start to regulate each one of those functions . ”
Already , scientist have devised cutting - boundary brain stimulation method to treat aesculapian disorder , like Parkinson ’s disease or grievous clinical depression . But current deep - brain approach involve trespassing surgery to implant electrode and stamp battery , and external ultrasound stimulation ca n’t bottom “ the deep brain circuits where many diseased circuits occupy , ” Tyler writes atArmed With Science .
Now , Tyler and his research team have created a “ transcranial pulsate ultrasound ” that ’s able-bodied to hasten a myriad of encephalon circuits from the outside in . The gadget has already proven open of point deep encephalon regions , unlike existing methods . And it ’s capable of zeroing in on exceedingly specific brain zones , as small as two or three millimeters . Plus , epitome devices are small enough to be fitted inside a distinctive helmet .
“ die deeply beneath the skull and have super specific spacial resolution are two huge advantages over exist approaching , ” Tyler says . “ Depth and specificity are what allow the ultrasound to do what other methods ca n’t . ”
With Darpa ’s financial support , Tyler plans to expand the uses of the ultrasound and improve the machine ’s spatial resolution even more , wee it a veritable all - in - one psyche stimulation machine . Using a microcontroller twist , the ultrasound would stimulate different brain regions to encourage troop alertness and noesis , ease stress and pain , and protect them against traumatic brain injuries .
“ The really damaging part of a TBI is n’t the initial injury , ” Tyler says . “ It ’s the metabolic damage , the liberal radicals and the swelling that are happen in the hour subsequently . If you could flick your remote and trigger an immediate interposition , you ’d be curbing what might otherwise be lifelong learning ability price . ”
