    Surely consciousness is a CONCEPT and as such not suitable for detection

    You may ask a person (as I was required to do frequently) if a person was " aware of your surroundings" and a few like questions to guage the person's level of being conscious

    Consciousness goes one level higher, in such, the person is not only aware (perhaps just as important alert to their surroundings) and is conscious and alert of being conscious and alert along with being a independent entity able to act independently, not merely subject to forces outside of theirself

    I would contend once a entity gains the ability of being conscious and alert add a few more neurones to the processing unit and CONSCIOUSNESS will arise

    It is an emergent sophistication in sensory reception and awareness of meaning, evolved from the fundamental need for "life-sustaining energy " and "fight or flight" survival mechanisms.

    This sensory awareness begins very early in the cytoplasm of even single-celled organisms like the paramecium.

    Watch these Amoebas, microtubular pseudopods, hunt Parameciums that are trying to escape via their microtubular ciliary propulsion.


    and this perfect example of microtubule catastrophe, causing the loss of cytoplasm and the resulting death of this organism.

    How can billvon be missing his own point?

    Because it isn't relevant to the phenomenon we are discussing.

    But perhaps you misunderstand billvon and you are the one missing the relevance. Maybe billvon can confirm your understanding of the point he was making.

    In regard to ORCH OR this may be of interest.

    What is quantum coherence?

    Well yes, your post # 5 itself is 4 years old and all the objection mentioned in that post have been addressed and resolved. If you had read some of my posts you would be familiar with the current state of critical reviews.

    Most objections have been proven premature and some valid objections due to flawed maths have been addressed and corrected.

    There are no outstanding objections. There are still a number of unresolved questions, but there is currently no danger of an outstanding argument that would be fatal to ORCH OR or any of the similarly based competing hypotheses. ORCH OR is not the only proposition that uses terms like Orchestration, or Integration, or Global Workspace, all requiring a form of Reduction.

    Well I've just checked and here is the current version of the same link I posted in post 5 four years ago: https://en.wikipedia.org/wiki/Quantum_mind

    The text I quoted four years ago has not been changed. So it is false to say the objection have been overcome. They haven't. Orch-OR is just as much a dead end now as it was then - in fact more so, since more time has elapsed.

    Well, the text of the bible hasn't changed in 3000 years and it is still wrong.

    Signal transmission through elements of the cytoskeleton form an optimized information network in eukaryotic cells - Scientific Reports

    Multiple prior empirical and theoretical studies have demonstrated wire-like flow of electrons and ions along elements of the cytoskeleton but this has never been linked to a biological function. Here we propose that eukaryotes use this mode of signal transmission to convey spatial and temporal...

    And we have the rudimentary beginnings of a generalized conscious response system. In the brain, this may well be the model for the evolution of self-aware consciousness.

    And a little reminder of what the microtubule population in the cytoplasm and cytoskeleton of each individual cell in the body looks like.

    Now imagine 1oo trillion cells connected by 1000 trillion synapses in brain alone constantly processing and transporting electrochemical information.

    One can see that the resulting network is unmatched by any other physically connective structures.

    If consciousness emerges from somewhere at all, the microtubule network is the ONLY qualifying candidate, IMO.

    And this, your opinion isn't worth anything at all.

    Obviously, you are completely ignorant about this subject and have no clue as to what I am talking about. Try to inform yourself before you make a "contribution" to this conversation.

    If you cannot refrain from ad hominem , it's better you don't post at all and soil this informative thread with your NON-SENSE, ok?

    Of course it isn't!

    You haven't ruled out the possibility that consciousness emerges as a result of connections between neurons, way above the size scale of anything that's happening in microtubules.

    Without microtubules there isn't any connection. Synapses are the terminal ends of microtubule bundles inside axions and dendrites!

    All cellular connections at all scales are provided by microtubules. Doesn't anybody read any of the quoted science?

    What you are asking is if an electrical network can have an electric field without copper wiring inside the cable transporting the electricity. Can it?

    Do dendrites connect to synapses?

    Highlights
    . Axons are the cable-like extensions of neurons which wire the brain.
    . Axon formation and maintenance requires ordered microtubule (MT) bundles.
    . We discuss the mechanisms that regulate the de/polymerisation of axonal MTs.
    . We discuss the model of local homeostasis to explain the maintenance of MT bundles.

    My search led me to this astounding video.

    This video may be revelatory of interpretation of natural fractals and how this might affect consciousness.

    Do plants have a form of consciousness?
    If microtubules are associated with sensory data processes, they should affect the behavior of plants. Plants have microtubules in their cytoskeleton and cytoplasm


    And behold they do!

    The uncanny ability of microtubules to detect and control cellular responses and activities in flora as well as in fauna makes the microtubule network in cytoskeleton, cytoplasm, and neural network a prime candidate for consideration as a form of cellular proto-sentience in all eukaryotic organisms.
