The article deals with the philosophical problem field of modern neuroethics. The general idea of the state of modern neuroethics is given and it is shown that research in this area encompasses both fundamental problems that classically belonged to the field of philosophy research (for example, such as the problem of psychophysical dualism, the physical bases of consciousness, freedom of will and its interrelation with brain activity) and problems with applied orientation, explicating the ethical-social and legal dimension of innovation development in the field of neuroscience and actualizing the analysis of their social risks. It is shown that the development of neuro-ethics in the modern world became possible thanks to a special way of functioning of modern science, which was called the technology of science and to the development of the phenomenon of technological development ethification, which in practical terms was expressed in the study of the problem of the correspondence of the results of innovative scientific and technical projects to the interests of various social groups, their expectations and values, and also helped to determine the status of new technologies in relation to social reality. The article gives an idea of the existing normative field necessary for the development of neuro-ethics. On the basis of using the resource of discourse analysis of R. Harre, who singled out personal grammar (P-grammar), organism grammar (O-grammars) and molecular grammar (M-grammar), a philosophical analysis of such a problem of modern neuroethics as brain death was carried out. Also was given a structural description of new biotechnogenic identities of human being. The conclusion is drawn that the concept of brain death is an example of the conventional nature of scientific truth, the formation of which is influenced by various socio-cultural and economic factors. In the context of the development of neuroscience and the emergence of new methods of brain regeneration, it can be rethought.
