There is widespread acknowledgment that ethical oversight must keep pace with this rapidly evolving technology. B c ees present multiple concerns, from privacy to personal autonomy. Ethesists stress that users must retain full control of the devices outputs. Developers will have records of ses every communication and crucial data about their brain health. There is also a risk to participants that their devices might not be supported forever or that the companies that manufactured them fold.
Brain–computer interfaces (BCIs) implanted in the brains of people who are paralysed are allowing them to control prosthetics that are restoring a range of skills.
Although the field is relatively young, researchers are making rapid advances in the abilities that these implants can restore. In the past few years, commercial interest in BCIs has soared, but many hurdles remain before these implants can be brought to market.
