The Next-Generation Nonsurgical Neurotechnology (N3) program aims to develop high-performance, bi-directional brain-machine interfaces for able-bodied service members. Such interfaces would be enabling technology for diverse national security applications such as control of unmanned aerial vehicles and active cyber defense systems or teaming with computer systems to successfully multitask during complex military missions.

Because DARPA’s programs push the leading edge of technology, they are sometimes society’s first notable encounter with the societal dilemmas associated with new capabilities. DARPA pursues these technologies because of their promise, and the Agency is committed to exploring domains that could leave the Nation vulnerable if not pursued. But DARPA’s leadership and team members also understand that, in this pursuit, the Agency’s work will at times raise ethical, legal, security or policy questions that cannot and should not go unaddressed.

Previous efforts to understand brain injuries that result from nonkinetic explosive effects have focused only on a single explanation—blast overpressure. Improvised explosive device (IED)-induced injuries in Iraq, however, do not fit this hypothesis. Evidence indicates that traumatic brain injuries unique to blast exposure do not exhibit typical overpressure injuries, such as damage to gas-filled organs like lungs and bowel. DARPA’s Preventing Violent Explosive Neurologic Trauma (PREVENT) program is comprehensively evaluating the physics of the interaction between an IED blast and the brain and has identified which blast components are associated with neurologic injury.
Improved technology for military uniforms, body armor, and equipment saves the lives of thousands of Service members injured on the battlefield. Unfortunately, many of those survivors come home seriously and permanently wounded, suffering unprecedented rates of limb loss and traumatic brain injury. This crisis has motivated great interest in the science of and technology for restoring sensorimotor functions lost to amputation and injury to the central nervous system.
The Histology for Interface Stability over Time (HIST) effort identifies leading mechanisms of interface degradation and failure. HIST teams are also developing new invasive and non-invasive histology methods to assess neural-recording-interface status and performance, accurate predictive models of interface performance, and methods to reduce the time required to assess and develop robust interfaces.
