Neuroethics examines the ethical issues that arise from developments in brain sciences, that is, from the advancement in our understanding of the human brain and our ability to monitor and influence it, and from our improved understanding of the biological basis of agency. Neuroethics also deals with the implications of applying neurotechnologies, such as neuroimaging and psychotropic drugs, for ethical decision-making and human self-perception and self-understanding.
