The early oscillations, synapse formation, cognition attributed to receptors, ion channels actually depend on microtubules (MTs) not mentioned, nor mixed polarity MTs unique to dendrites and soma. Systems Neuroscience doomed by cartoon neuron doctrine. frontiersin.org/journals/molec…

I challenge YOUR statement. What type of simplified neurons can create what kind of simplified consciousness? What flow and control are needed? This is as vacuous an assertion as are cartoon neurons. frontiersin.org/journals/molec…

No, the collapse outcome in Penrose OR is selected neither randomly nor algorithmically but ‘non-computably’. This implies influence by Platonic values embedded in spacetime geometry. Schrödinger equation doesn’t describe collapse, just the process of the prior wavefunction.

Beautiful. How could the 1/16 beat get controlled by neuronal firings with one millisecond refractory time? I once heard bumblebees don’t have enough brain neurons to account for their flying abilities. It must ‘bee’ the microtubules at kilohertz, megahertz, gigahertz, terahertz.

Conscious intentionality depends on physics in quantum-friendly non-polar regions, and not wet chemistry where quantum states decohere rapidly. Denis Noble on right track but his ‘values’ need Orch OR conscious feelings which I think are necessary.

Agreed. Intuition could derive from Penrose Platonic values embedded in space time, along with Jungian archetypes, Akashic record … You access and are influenced by quantum Orch OR in your microtubules. x.com/teejip/status/…

Your grasp at consciousness is very tenuous. As Murad said on your website, ‘Simulated thinking is not thinking’. As Roger said ‘consciousness is non-computable’.

Penrose deduced through Goedel’s theorem that consciousness was noncomputable, and the only source for that was self-collapse/state reduction of the quantum wavefunction by an objective threshold in general relativity context. Objective Reduction (OR). Read ‘Emperor’s New Mind’

You need 1) discrete events, sequences give consciousness (like film, video frames) 2) collapse for causal action, selecting perceptions, actions and qualia 3) a predictive formula for OR events at times t = h/E, form of uncertainty principle.

Penrose says particles go into superposition then reach OR threshold, collapse to classical states,go back into superposition, reach OR threshold…over and over and over. Cyclically. They may also have intrinsic oscillations as in Anirban’s time crystals

The retina is part of the brain, and rods and cones each have microtubule-based cilia through which photons must pass. So yes it’s possible. Cilia in all primitive visual systems, probably do lots more in our eyes too, extract quantum information from photons?

A movie or video is a sequence of frames at about 30 Hz. Our conscious experience of it is continuous, not a series of frames. Consciousness is a sequence of conscious Orch OR moments which is continuous because we’re not conscious in between. The rate may vary as mood.

Dave hasn’t a clue on consciousness in the brain but claims it will occur in AI. He’s ignored and suppressed Orch OR, pushed useless IIT, dropped the hard problem, and sucked up to AI. They say politicians smile when they’re losing. Dave’s smiling a lot lately.

It’s only circular if you have both an observer/self and the experience. In Orch OR they are one. t =h/E events are instantaneous among many entangled tubulins, rearrange Planck scale geometry and generate qualia experience. frontiers-in.org/journals/molec…

The best test for Consciousness is anesthesia which dampens quantum optics in microtubules. Despite the most evidence, Orch OR suppressed, banned by Chalmers, Koch, Seth, ASSC. So including Orch OR ‘in the debate’ is all I’m asking for. But they won’t debate me. 🐓🐓🐓

Neurons can be selective at the membrane level, but mixed/inclusive (like binding) in deeper, faster, (and quantum) microtubule representations inside neurons. These are coherent and fractal-like. Not complex, more simplified, entangled, holographic. frontiersin.org/journals/molec…

Stuart Hameroff (@stuarthameroff) 's Twitter Profile Photo

Free will requires quantum state reduction by Orch OR with retroactivity to avoid consciousness coming too late. It may be deterministic but is neither random nor algorithmic. Born rule holds on average. Read this please: frontiersin.org/journals/integ…

Unicellular organisms have cognition via microtubules, and an amoeba can solve the traveling salesman problem. Why not organoids? Here’s a paper about testing for consciousness in organoids I wrote with UCSD organoid expert Allysson Muotri. researchtrends.net/tia/article_pd…

More evidence that 1) anesthesia acts on, and 2) consciousness comes from microtubules. The microtubule stabilizer drug epothilone B delays anesthetic-induced unconsciousness in rats. Congrats to MC Wiest and Wellesley team! wellesley.edu/news/wellesley…
