The purpose of this article is to determine the objectivity of culture from the perspective of the neuroscience`s research interests of and to identify neuroethical problems that arise in the process of using neurotechnologies and applying research results. The following aspects were set: to provide a clear understanding of the reasons behind neuroscience’s growing interest in culture; to identify new scientific and neurobiological directions studying the relationship between a culture and humans; to substantiate the importance of the emergence of cultural neuroscience, to identify some ethical categories revealed through analysis of research results; to highlight ethical problems that arise or may arise near future during the application of neurotechnologies and the use of research results in this field. The main conclusion of this article is that the development and application of neurotechnologies will be the main priority for many countries, especially taking into account the interest in understanding the cultural characteristics of all people living in the same territories. On the one hand, the knowledge can help to prevent cross-cultural conflicts and improve the effectiveness of management systems in the social sphere. On the other hand, it may lead to bioethical problems due to possible manipulations in various fields as business and politics.
