Due to advances in computing and sensor technologies, the production and marketing of a number of neurotechnologic devices is increasing.  Brain-machine interface (BMI) devices are being developed for a variety of uses, from the treatment of neuropsychiatric disorders, to commercially available controls for computer games.  In this commentary we argue that any consideration of neurotechnological interventions and interfaces must: 1) be regulated and controlled if and when used in devices that will be available to the general public; and, 2) be subject to similar controls when employed in clinical settings, with the additional proviso that any and all such therapeutic treatments be rendered by trained specialists who are well-qualified to soundly steward the knowledge, and skills required to uphold right and ethically good care. In support of this, we provide a notional framework meant to help guide the development of research and policy on the ethical, legal, and social issues of brain-machine interface (BMI) neurotechnologic devices.
