Abstract:

At present， the application of brain-computer interface technology has shown a trend of continuous extension and expansion from treatment to enhancement， the information flow has expanded from “brain to computer” to “computer to brain”， and the application mode has also shown a trend of invasive re-emergence. The risk has also expanded or turned： the purpose of enhancement has the risk of creating new inequality， the information flow from machine to brain poses the problem of endangering human autonomy， and the way of invading human brain has the crisis of risk dispersion. Therefore， first of all， the brain-computer interface should be deconstructed and the governance focus should be arranged according to the risk characteristics and approach orientation of different technologies. Secondly， according to the diachronic order of technology （policy）-ethics-law， the power of risk regulation is allocated step by step. Finally， by establishing a dynamic consent mechanism， strengthening the follow-up review mechanism and clarifying the responsibility allocation system， the full-cycle regulation of brain-computer interface application can be realized.

Key words: brain-computer interface, artificial intelligence, technological risk, application extension, risk evolution
