The Defense Advanced Research Projects Agency (DARPA) mission is to create breakthrough technologies for US national security and to protect the health of U.S. service members and veterans.

To better address the health needs of service members and veterans, DARPA has launched four programs that support the goals of the BRAIN Initiative: RAM (Restoring Active Memory), RAM Replay, HAPTIX (Hand Proprioception and Touch Interfaces), and SUBNETS (Systems-Based Neurotechnology for Emerging Therapies).
