New BRAIN Initiative K99/R00 Career Transition award to promote diversity, women, and individuals from diverse backgrounds.

In a recent interagency program solicitation, the National Science Foundation (NSF) announced funding opportunities for the Smart and Connected Health (SCH) program. Related to the SCH program, the National Institute of Neurological Disorders and Stroke (NINDS) is soliciting applications directed at the treatment of pain.

The meeting will convene BRAIN Initiative awardees, staff, and leadership from contributing federal agencies, plus representatives and investigators from participating non-federal organizations, and members of the media, public, and Congress. This open meeting provides a forum for discussing exciting scientific developments and potential new directions, and to identify areas for collaboration and research coordination.
