Large brain projects worldwide, such as the American BRAIN initiative and the European Human Brain Project, are generating vigorous moral discussions on a number of topics. They range from how responsible research should be carried out and how to ethically use the findings, to critical questions about the impact of neuroscientific findings on human lives in general and subjective human experiences in particular. One important concern that has been voiced is that advances in brain research can potentially threaten human identity either by substantially altering it or by directly undermining it. In this paper, the author identifies and presents some of these identity related concerns.
