should be proposed as exploratory research and planning activities to establish feasibility and early-stage development that, if successful, would support, enable, and/or lay the groundwork for a potential, subsequent research project grant applications using invasive neural recording and stimulation technologies in the human brain. Projects should maximize opportunities to conduct innovative in vivo human neuroscience research made available by direct access to the brain from invasive surgical procedures. Projects should employ approaches guided by specified theoretical constructs and by quantitative, mechanistic models where appropriate. Recipients will join a consortium working group, coordinated by the NIH, to identify consensus standards of practice, including neuroethical considerations, to collect and provide data for ancillary studies, and to aggregate and standardize data for dissemination among the wider scientific community.
