The volume has three parts: 1) Past, Present and Future of BCI technology, 2) Ethical and Philosophical Issues and 3) Legal and Policy Implications. The rich and detailed picture of the field of BCI ethics with contributors from various fields and backgrounds, from academia and from the commercial sphere may serve as an introductory textbook into the neuroethics of BCI, or as a resource for neuroscientists, engineers, and medical practitioners to gain additional insight into the ethical and policy implications of their work.
