Abstract: The subject of the study is the relation of consciousness and physical reality, which is considered in the context of the modification proposed by the author of the theory of quantum measurement of Everett-Mensky. In this connection, the conceptual basis of measurement theory in quantum mechanics is also explored, in particular, the possibility of modifying the Everett interpretation of the measurement process in such a way as to exclude the need for any "splitting" of both the universe and the observer entity is investigated. Further, it is investigated how from the received picture of measurement it is possible to receive conclusions concerning character of communication of consciousness and quantum reality. The research methodology is based on the principle of interdisciplinarity (related issues of philosophy of physics and philosophy of consciousness), comparativeness and system analysis. An original approach to the solution of the psychophysical problem based on the philosophically rethought "multi-world" interpretation of quantum mechanics by H. Everett is proposed, as well as Mensky's idea of the identity of awareness with the process of selection of the quantum alternative. An explanation is given of the apparent psychophysical interaction (when the principle of the causal closure of the physical universe is taken into account) and the process of reduction of the wave function in quantum mechanics.

Abstract: The author of the article discusses the hypothesis offered by Henry Bergson about extrasomatic ('out of the body') nature of a certain element of permanent memory. Based on the hypothesis, at least some part of the permanent memory exists as a direct access to the past (in the form of past states of mind or consciousness) but not as an engram (recording). The author provides grounds for this hypothesis from the point of view of psychology, neuroscience and philosophy. He also viwes possible mechanisms of extrasomatic memory and offers his own concept of 'consciousness in the quantum world'. This concept continues Everett-Mensky's theory on the relation between consciousness and quantum reality. The author also studies some additional aspects of the model of 'consciousness in the quantum world' associated with the role of brain in performance of psychic processes and the nature of space and time. The author also analyzes how this model can be used to explain the process of biological evolution.
