The acronyms for the four BRAIN Initiative related IARPA programs are ICArUS. MICrONS, KRNS, and SHARP.

The Intelligence Advanced Research Projects Activity (IARPA) invests in high-risk, high-payoff research programs to tackle some of the most difficult challenges of the agencies and disciplines in the Intelligence Community (IC). IARPA does not have an operational mission and does not deploy technologies directly to the field. Instead, IARPA facilitates the transition of research results to our IC customers for operational application.
