Dear ResearchGate community,
My recent work, "The Phenomenological Trace: A Neuro-Quantum Model of Consciousness Based on the Fractal Geometry of Microtubules," dares to confront one of the most notorious and persistent "killers" of quantum theories of mind: Tegmark's decoherence problem. Tegmark argued, compellingly, that any coherent quantum state in the brain would dissipate on timescales too short to be functionally relevant to consciousness. This critique, supported by figures such as Koch and Hepp, has relegated many neuro-quantum proposals to the realm of speculation.
However, my model, the "Phenomenological Trace," proposes a radical paradigm shift: instead of trying to "catch" the ephemeral quantum event itself, we must search for its "echo"—a residual classical energetic "trace" left in the neural structure. I postulate that the ideal physical substrate for the generation and detection of this trace resides in the fractal geometry of microtubules, whose self-similarity across scales provides an optimal architecture for quantum information processing. The conscious detection of this "trace" would correspond to the psychological experience of "insight" or "Aha!", whose empirical signature is a burst of gamma waves.
The question I pose to the scientific community, with the intention of generating an honest and, perhaps, uncomfortable debate, is the following:
If the "Phenomenological Trace" solves the "decoherence problem" by not requiring direct observation of the quantum state, but rather of its classical "echo," are we truly solving the enigma of quantum consciousness, or are we simply shifting the complexity of how the quantum influences the classical to a new layer of neurobiological mystery: how the brain "reads" or "tunes" this subtle "trace"?
Beyond "insight" or "Aha!", if the brain has the ability to "tune in" to these residual traces, could my model offer a way to explain other elusive phenomena of consciousness, such as the enigmatic Déjà Vu?
Let me be even more provocative: Déjà Vu is a well-studied psychological phenomenon, but curiously, none of the existing theories—be it parallel processing, fragmented memory, split perception, or memory similarity—has achieved a definitive explanation or unanimous universal acceptance. They all offer plausibility, but lack the "silver bullet" that science seeks. Isn't this precisely the gap where a fundamentally new perspective, such as the "Phenomenological Trace" of a neuroquantum event, could not only shed light, but perhaps offer the missing piece to a puzzle that classical neuroscience alone has been unable to fully solve?
Could this "trace" be an underlying mechanism that explains the feeling of having "already lived" an experience, or are we simply extending speculation into another realm without a solid empirical basis for these cases?
I look forward to your arguments and critiques!
