The purpose of the article is an interdisciplinary analysis of the concepts of «neurophilosophy» and «neurobibliology» in the system of cognitive sciences as varieties of cognitive sciences. It shows the importance of a new formulation of the problem. Neurophilosophy is an area of interdisciplinary research based both on knowledge of the neurophysiological foundations of mental phenomena and on computer methods for modeling brain activity. The brain cannot be understood without the problem of subjective experience and consciousness, but consciousness cannot be understood without studying the brain. Academician of the Russian Academy of Sciences K.V. Anokhin considers the problems of creativity in the context of the cognitome / connectome construction. The cognitome is a reflection of the system of subjective experience, and the connectome is the architecture of the body's neural network. According to K.V. Anokhin, the book is an external cognitome. The author proposes the concept of neurobibliology as an interdisciplinary scientific direction at the intersection of bibliology and the theory of cognitive processes. It is based on the «cognitome» research program. The key object of study of neurobibliology is the «book – book business – reader» system in relation to the brain mechanisms of the behavior of the cognitome. The book science of neurosciences is a study of book science concepts of library science, bibliographic studies, reader studies, which underlie a particular neuroscience, as well as the study and analysis of the goals, methods, and problems of individual neurosciences. Thus, bibliology of neurosciences can be considered as a derivative of neurobibliology, which forms and solves the problems of neurosciences. Neurobibliology and bibliology of the neurosciences can be defined more as «a complex knowledge science» than «a complex cognitive science».
