Abstract

This paper presents an explanation for the neural basis of consciousness from the perspective of the QBIT theory. It is hypothesized that consciousness is substrate-dependent, and the substrate of consciousness is tubulin. Consciousness depends on the spontaneous emergence of coherence in a population of microtubules located at the axon initial segments of cortical neurons. When quantum coherence spontaneously emerges in a system consisting of many microtubules, the resultant entity is a kind of matter-field. Different configurations of this field correspond to different conscious experiences. © 2025 Elsevier B.V., All rights reserved.
