Summary
AI-generated from the abstractMicrotubules, nanoscale structures within neurons, can act as spintronic oscillators with memristive properties. Under specific conditions in the axon initial segment, these properties allow quantum coherence to emerge spontaneously in a population of microtubules. According to QBIT theory, this spontaneous coherence is both necessary and sufficient for the brain to generate a micro-consciousness, or quale. The simultaneous generation of multiple qualia through synchronized activity across different parts of the cerebral cortex creates the appearance of a unified macro-consciousness, or a seemingly unified subjective experience.

Abstract
Microtubules are nanoscale spintronic oscillators with memristive properties. Spintronic and memristive effects, together with some unique conditions found in the axon initial segment (AIS), allow quantum coherence to emerge spontaneously in a population of microtubules located within the AIS. According to the QBIT theory, the spontaneous emergence of coherence in a population of microtubules is the necessary and sufficient condition for the generation of a micro-consciousness (a quale) by the brain. Simultaneous generation of multiple qualia by synchronized activity in different parts of the cerebral cortex gives rise to the appearance of a macro-consciousness: a seemingly unified subjective experience.
