The neural basis of consciousness is a central issue in the field of neuroscience, with the "hard problem" of consciousness revolving around the unclear physical origin of subjectiveexperience. Existing theories (such as IIT, GWT, etc.) are confined to information-logicrecursive frameworks, failing to identify core physical structures and often focusing on thecortex, which contradicts clinical evidence that thalamic damage leads to loss of consciousness.To address these limitations, this paper proposes and argues that the central medial thalamicnucleus (CM) is the core anchor for consciousness generation. Using the Consciousness Flow Vortex Model (CFVM) as an analytical framework, the study systematically elucidates CM's critical role in information convergence, rhythm regulation, and global integration from three dimensions: closed-loop cycles, central focusing, and global synchronization. The analysis demonstrates that CM can serve as the central anchor for consciousness production, effectively explaining the characteristics of awareness, integration, stability, and subjectivity in consciousness. This hypothesis not only constructs a comprehensive theoretical model for consciousness research but also provides a clear structural localization for the neuralmechanisms of consciousness, offering new opportunities for breakthroughs in theneuroscience of consciousness.
