The 10-year Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative is now nearing the halfway point, transitioning from its first stage of developing tools for research to its second stage of using those tools to "make fundamental discoveries about how brain circuits work and what goes wrong in disease." The NIH is requesting information to "help inform their discussions of the BRAIN Initiative's progress and potential updates to the plan moving forward." Responses are due November 15, 2018, and must be submitted electronically using the web-based form or via email to BRAINFeedback@nih.gov with "BRAIN RFI" in the subject line.
