Novel neurotechnologies, like deep brain stimulation and brain‐computer interface, offer great hope for treating, curing, and preventing disease, but raise important questions about effects these devices may have on human identity, authenticity, and autonomy. After briefly assessing recent narrative work in these areas, we show that agency is a phenomenon key to all three goods and highlight the ways in which neural devices can help to draw attention to the relational nature of our agency. Drawing on insights from disability theory, (...) we argue that neural devices provide a kind of agential assistance, similar to that provided by caregivers, family, and others. As such, users and devices participate in a kind of co‐agency. We conclude by suggesting the need for developing relational agency‐competencies—skills for reflecting on the influence of devices on agency, for adapting to novel circumstances ushered in by devices, and for incorporating the feedback of loved ones and others about device effects on agency.

Deep brain stimulation (DBS) uses electrodes implanted in the brain to modulate dysregulated brain activity related to a variety of neurological and psychiatric conditions. A number of people who use DBS have reported changes that affect their sense of self. In the neuroethics literature, there has been significant debate over the exact nature of these changes. More recently, there have been suggestions that this debate is overblown and detracts from clinically-relevant ways of understanding these effects of DBS. In this paper, (...) we offer an alternative approach to understanding the effects of DBS on the self, drawing on John Sadler’s work on self-illness ambiguity. We argue that self-illness ambiguity is a complex concept, with at least three different aspects, and that each of the three aspects we identify also characterizes one kind of DBS-related change. Our analysis also suggests ways of helping patients to adjust to life as a DBS user. (shrink)
