[Neuroethics--a future discipline?].

Progress in neuroscience leads not only to novel therapeutic opportunities but also raises several ethical problems. These problems are often subsumed under the term "neuroethics," of which the definition and purpose often remain unclear. We discuss the problems of informed consent, free will, sense of self, and personality in light of recent neuroscientific progress. Due to distinct categories and frames of reference, these philosophical-ethical terms cannot be limited only to the brain; the development of systematic relations is suggested. This accounts for the "special ethical position of the brain." It is concluded that only this sense can neuroethics account for the ethical complexity in neuropsychiatric disorders.
