Systems-Based Neurotechnology for Emerging Therapies (SUBNETS)

"The Systems-Based Neurotechnology for Emerging Therapies (SUBNETS) program aims to improve force health by using neurotechnology as the basis for effective, informed, and precise treatments for neuropsychiatric illnesses in military Service members. The effects of such illnesses, brought on by war, traumatic injuries, and other experiences, remain challenging to treat. Current treatment approaches-surgery, medications, and psychotherapy-can often help to alleviate the worst effects of illnesses such as major depression and post-traumatic stress, but they are imprecise and not universally effective. Through SUBNETS, DARPA seeks to generate the knowledge and technology required to deliver relief to patients with otherwise intractable neuropsychiatric illness. The SUBNETS vision is distinct from current therapeutic approaches in that it seeks to create an implanted, closed-loop diagnostic and therapeutic system for treating, and possibly even curing, neuropsychiatric illness. That vision is premised on the understanding that brain function-and dysfunction, in the case of neuropsychiatric illness-plays out across distributed neural systems, as opposed to being strictly relegated to distinct anatomical regions of the brain. The program also aims to take advantage of neural plasticity, a feature of the brain by which the organ's anatomy and physiology alter over time to support normal brain function. Because of plasticity, researchers are optimistic that by using SUBNETS-developed technology the brain can be trained or treated to restore normal functionality following injury or the onset of neuropsychiatric illness."
