||Neuroethics is a nascent subdiscipline that has emerged out of bioethics and neuroscience to consider the ethical issued raised by developments in neuroscience, particularly recent developments in neuroetechnologies. The scope of neuroethics is broad and heterogeneous. In her seminal 2002 paper, philosopher and neuroscientist Adina Roskies bisected the field of neuroethics into two broad sectors: the ethics of neuroscience, and the neuroscience of ethics. The ethics of neuroscience overlaps significantly with traditional issues in biomedical ethics, including the ethics of neuroscientific research, and the ethical, legal, and social implications of new developments and discoveries in neuroscience. The “neuroscience of ethics” engages with traditional ethical questions, and (controversially) overlaps with neurophilosophical, metaphysical inquiries concerning free will and personal identity as they inform and interact with important ethical and social issues. Specific areas of neuroethical interest include: cognitive enhancement, disorders of consciousness and neurological impairment, psychiatric disorders, brain imaging, free will/moral responsibility, and addiction, and the neuroscientific study of morality and decision-making.
