Intracranial electrical recordings and neuro-stimulation of neurosurgical patients have made fundamental contributions to our understanding of vision, speech, decision making, memory, and sensorimotor processing. The use of these methods has burgeoned over the last decade due to technological advances and an increase in the number of patients undergoing neurosurgery for different neurological disorders.

Recent meetings of the Multi-Council Working Group (MCWG) for the NIH BRAIN Initiative and the MCWG Neuroethics Division provided updates on BRAIN’s scientific progress, considerations of the neuroethical issues surrounding the science, and discussions on how to continue working toward the goals of the BRAIN 2025 report…

In December, the NIH BRAIN Initiative held its third annual BRAIN Initiative Investigators Meeting, gathering experts from around the globe to share their cutting-edge BRAIN-funded research. The attendees spent three days learning about each other’s work, forming new collaborations, and hearing from members of the BRAIN Initiative Alliance.

Advances in neurotechnology are aimed at helping us better understand normal brain function and how to treat dysfunction associated with brain disorders. These technological advances carry potentially profound ethical implications. A set of recently published articles highlight how the NIH BRAIN Initiative is working to integrate neuroethics in neurotechnology research and development.

Despite being a relatively new effort, research funded under the NIH BRAIN Initiative already is producing new technologies and methods
