A planning committee of the National Academies of Sciences, Engineering and Medicine will organize a public workshop to examine scientific, technical, ethical, and regulatory issues related to brain-machine interfaces (BMIs) and related neural interface technologies. The workshop will: 1) review advances in BMI and related neural interface technologies; 2) consider current and future applications; and 3) examine ethical and regulatory issues associated with their use. The workshop will feature invited presentations and discussions that may consider such topics as: 1) the implications of BMIs and related neural interface technologies for user autonomy and privacy; 2) issues associated with private party collection and use of data obtained by BMIs and related neural interface technologies; 3) U.S. and International regulatory frameworks governing the use of BMIs and related neural interface technologies; and 4) potential regulatory gaps in U.S. Food and Drug Administration (FDA) and Federal Trade Commission (FTC) oversight of these technologies. A proceedings in brief prepared in accordance with institutional guidance by a designated rapporteur will be issued following the workshop.
