quantum consciousness microtubules

They are beholden to particular interpretations of quantum mechanics and this is far from a settled field, to put it mildly. But it is worthwhile to try and draw a rough circle around the problematic features of conscious experience, if we can. The apparent differences here may be more one of style than of substance, despite the intricacies of these metaphysical debates. And as to the question of why this particular neural state should be identical to this particular phenomenal state, the answer is that this is just the way things are. as follows: "junctional communication may provide metabolic and electrotonic interconnections between neuronal and astrocytic networks at early stages of neural development and such interactions are weakened as differentiation progresses. In more detail, the challenge arises because it does not seem that the qualitative and subjective aspects of conscious experience—how consciousness “feels” and the fact that it is directly “for me”—fit into a physicalist ontology, one consisting of just the basic elements of physics plus structural, dynamical, and functional combinations of those basic elements. Perhaps, though, we know enough already to establish that consciousness is not a physical phenomenon. On October 6, 2009, my 20-year-old son Erik, took his own life. An amazing set of experiments suggest that events in the future may influence things happening in the world now. The main difference between such claims by reductionists and by mysterians is that the mysterians reject the idea that current reductive proposals do anything at all to close the gap. This amounts to a rejection of the idea that experience is simple and basic, that it stands as a kind of epistemic or metaphysical “ground floor.”  Strong reductionists must hold that consciousness is not as it prima facie appears, that it only seems to be marked by immediacy, indescribability, and independence and therefore that it only seems nonfunctional and intrinsic. Our conscious mental lives are not themselves quantum phenomenon—how, then, do micro-phenomenal quantum-level properties combine to constitute our experiences? Hameroff's 1998 hypothesis required that cortical dendrites contain primarily 'A' lattice microtubules,[47] but in 1994 Kikkawa et al. What came first, you or the universe? The Penrose-Hameroff theory of quantum consciousness argues that microtubules are structured in a fractal pattern which would enable quantum processes to occur. Rather, you find the tree, as it appears to you, as you represent it. Deductive entailment is a logical relation where if the premises of an argument are true, the conclusion must be true as well. A review and update of a controversial 20-year-old theory of consciousness published in Physics of Life Reviews claims that consciousness derives from deeper level, finer scale activities inside brain neurons. David Chalmers coined the name “hard problem” (1995, 1996), but the problem is not wholly new, being a key element of the venerable mind-body problem. A weak reductionist might hold that this is a question we at present cannot answer. You should enjoy this book, and it should help you on your personal journey to understanding.”—Richard Conn Henry, Professor of Physics and Astronomy, Johns Hopkins University, “It is genuinely an exciting piece of work…and coheres with some of the things biology and neuroscience are telling us about the structures of our being. The direct access of phenomenal concepts seems to require that phenomenal states themselves inform us of what they are like. Get cozy and expand your home library with a large online selection of books at eBay.com. Hameroff (1994)), who has been conjecturing on the computational capacities of microtubules … For example, the gene may be reductively explained in terms of DNA as follows: Chalmers contends that such reductive explanations are available in principle for all other natural phenomena, but not for consciousness. They agree that there is a real gap at present between consciousness and the physical and they agree that nothing in current science seems up to the task of solving the problem. In this provocative book, he argues that fashion, faith, and fantasy, while sometimes productive and even essential in physics, may be leading today's researchers astray in three of the field's most important areas—string theory, quantum ... Another strongly reductive approach holds that conscious states are states representing the world in the appropriate way (Dretske 1995, Tye 1995, 2000). The HOT theory of consciousness: Between a rock and a hard place? [14][15] Koch and Hepp concluded that "The empirical demonstration of slowly decoherent and controllable quantum bits in neurons connected by electrical or chemical synapses, or the discovery of an efficient quantum algorithm for computations performed by the brain, would do much to bring these speculations from the 'far-out' to the mere 'very unlikely'. Putting these two ideas together, we find a motivation for the sorts of views canvassed here. Both groups plan to test whether anaesthetics, which switch consciousness on and off, have any impact on microtubules … Fractals are structures that are neither two-dimensional nor three-dimensional, but are instead some fractional value in between. if you like our Facebook fanpage, you can read everyday such amazing stories. Found insideThis book presents an extensive treatment of the introduction of modern physical concepts into biology. This Text Is Divided into 14 Sections with 70+ Chapters Section I. Cosmology of Consciousness Section II. Brain and Mind Section III. argued that aromatic molecules cannot switch states because they are delocalised; and that changes in tubulin protein-conformation driven by GTP conversion would result in a prohibitive energy requirement.[37][33][38]. Can Objects And Machines Be Made To Think. Our brains are composed of cells called neurons, and their combined activity is believed to generate consciousness. Brain neuron axon showing the network of microtubules. If death doesn’t exist, then what happened to your dog? Whenever there is a physical cause of behavior, the underlying phenomenal (or neutral) basis will be present to do the work. [32] He then proposed a Frohlich condensate, a hypothetical coherent oscillation of dipolar molecules. And if qualia are essential to consciousness, this, too, amounts to an eliminativism about consciousness. First, it is again the case that phenomenal properties are posited at an extreme micro-level. Explaining why consciousness occurs at all can be contrasted with so-called “easy problems” of consciousness:  the problems of explaining the function, dynamics, and structure of consciousness. Taking the reader on a fascinating tour of both Western and Eastern thought, Wolf explains the differing view of the soul in the works of Plato, Aristotle, and St. Thomas--the ancient Egyptian's believe in the nine forms of the soul/ the ... Sometime in the future science life will finally figure out how to escape from its corporeal cage. Non-stationary wave functions are linear combinations of the eigenstates of the system, a phenomenon described by the superposition principle. We assume there’s a universe “out there” separate from what we are, and that we play no role in its appearance. Nature appears to be composed of two completely different kinds of things: rocklike things and idealike things. First-order representational states are conscious because they do the right thing:  they make us aware of just the sorts of features that make up conscious experience, features like the redness of an apple, the sweetness of honey, or the shrillness of a trumpet. Aufbau. Found insideOur current theories about conscious life-of people, animal, even robots--are transformed by the new perspectives found in this book. Consciousness might be the one thing that is certain in our epistemology. Hameroff frequently writes: "A typical brain neuron has roughly 107 tubulins (Yu and Baas, 1994)", yet this is Hameroff's own invention, which should not be attributed to Yu and Baas. Science, IT, Nature. On this view, it is metaphysically possible that the physical substrate occurs without the phenomenal properties, indicating their ontological independence, but phenomenal properties cannot exist on their own. And since representation can plausibly be reduced to functional/physical processes, there is no lingering problem to explain (though see Gennaro 2005 for more on this strategy). The quantum mind or quantum consciousness is a group of hypotheses proposing that classical mechanics cannot explain consciousness. WIRED [Read More]Discover Magazine [Read More]. quantum coherence) and of a newly proposed physical phenomenon of quantum wave function “self-collapse” (objective reduction: OR - Penrose, 1994) are essential for consciousness, and occur in cytoskeletal microtubules and other structures within each of … Chalmers explains the persistence of this question by arguing against the possibility of a “reductive explanation” for phenomenal consciousness (hereafter, I will generally just use the term ‘consciousness’ for the phenomenon causing the problem). But conscious experience instead reveals various sensory qualities—the redness of the visual experience of an apple or the painfulness of a stubbed toe, for example. This is the hard problem of consciousness. Quote from pissedlizard on July 3, 2021, 9:00 am. Robert Lanza claims the theory of biocentrism says death is an illusion. If a state is available to the mind in this way, it is a conscious state (see also Dennett 1991). In this paper we propose that aspects of quantum theory (e.g. Kriegel labels this feature the subjective component of consciousness. The idea is that consciousness arises when gravitational instabilities in the fundamental structure of space-time collapse quantum wave functions in tiny proteins called microtubules, which are found inside neurons. It is because we, the physicists, do NOT say it–or if we do say it, we only whisper it, and in private–furiously blushing as we mouth the words. Weak reductionism, in contrast to the strong version, holds that consciousness is a simple or basic phenomenon, one that cannot be informatively broken down into simpler nonconscious elements. Why are we here? Further, these representations are “nonconceptual” in nature:  they represent features even if the subject in question lacks the concepts needed to cognitively categorize those features. The hard problem was so-named by David Chalmers in 1995. It may just seem obvious that consciousness could not be physical or functional. Still, it may be that some future conceptual revolution in the sciences will show how to close the gap. It follows that there is no further hard problem to deal with. The lack of a functional analysis is also shown by the continued conceivability of spectrum inversion (perhaps what it looks like for me to see green is what it looks like when you see red), the persistence of the “other minds” problem, the plausibility of the “knowledge argument” (Jackson 1982) and the manifest implausibility of offered functional characterizations. Lanza (with Barnard & Cooper), JAMA 249; 1746 (1983) Then we find what neural processes are reliably correlated with those reported experiences. Religion vs. Science’s Answers to the Big Questions. “Two Dogmas of Empiricism.”. There seems to be an unbridgeable explanatory gap between the physical world and consciousness. However, Penrose determined that wave function collapse was a prime candidate for a non-computable process. The Orch-OR Theory. We’re all ephemeral forms of an individuality greater than ourselves, eternal even when we die. But whether awake or dreaming, you’re experiencing the same bio-physical process. The hypothesis combines approaches from molecular biology, neuroscience, pharmacology, philosophy, quantum information theory, and quantum gravity. The Hundred Greatest Mathematicians of the Past. What’s more, if we take the panpsychic route, we are faced with the claim that every physical object has a phenomenal nature of some kind. Quantum consciousness theory suggests that microtubules are shaped as "fractal patterns" that allow quantum processes to occur. Phenomenal properties, on this view, may be lawfully correlated with physical properties, thus assuring that whenever a brain event of a particular type occurs, a phenomenal property of a particular type occurs. However, there remains considerable resistance to strongly reductive views. But once we understand the differences in the two concepts, there is no need to accept this intuition. Josh Weisberg quantum coherence) and of a newly proposed physical phenomenon of quantum wave function "self-collapse" (objective reduction: OR - Penrose, 1994) are essential for consciousness, and occur in cytoskeletal microtubules and other structures within each of … Lanza (with Skinner & Epstein), SCIENCE 212; 695 (1981) The author of … Lewis, D.K. Hameroff reasoned that such condensate behavior would magnify nanoscopic quantum effects to have large scale influences in the brain. A dual-aspect view holds that there is one basic underlying stuff that possesses both physical and phenomenal properties. Causal closure is a long-held principle in the sciences, so its rejection marks a strong break from current scientific orthodoxy (though see Collins 2011). Still, this is an alluring area of investigation, bringing together the mysteries of consciousness and quantum mechanics. Brains and fractals. Most physical laws are computable, and thus algorithmic. Quantum mechanics plays an essential role in the understanding of human consciousness; specifically, he believes that microtubules within neurons support quantum superpositions. [29][30] Throughout the 1990s, the two collaborated on the Orch OR theory, which Penrose published in Shadows of the Mind (1994). “Psychophysical and Theoretical Identifications.”. Found insideFrom the emergence of life at deep-sea vents to solar-powered starships sailing through the galaxy, from the Big Bang to the intricacies of intelligence in many life forms, acclaimed author Ann Druyan documents where humanity has been and ... But surely she still lacks some knowledge of what it’s like to see red, for example? The answer lies in your own backyard. If collapse is truly random, then no process or algorithm can deterministically predict its outcome. Earlier versions of the theory had required tubulin-electrons to form either Bose–Einsteins or Frohlich condensates, and the Reimers group noted the lack of empirical evidence that such could occur. Neurological and phenomenal properties do not seem to be basic in this way. The theory that blew your mind in Biocentrism and Beyond Biocentrism is back, with brand-new research revealing the startling truth about our existence. Or the term may serve no use at all in any scientific theory, and so may drop out of a scientifically-fixed ontology (Rey 1997). Representation, even the sort of representation involved in experience, is no more than various functional/physical processes of our brains tracking the environment. Still, there may be good reasons to hold at present that the most parsimonious metaphysical picture is the physicalist picture. To see this, note that even when we have explained the performance of all the cognitive and behavioral functions in the vicinity of experience—perceptual discrimination, categorization, internal access, verbal report—there may still remain a further unanswered question:  Why is the performance of these functions accompanied by experience? They must be poised to influence the higher-level cognitive systems of a subject. “My special guest is Dr. Robert Lanza and his extraordinary mind, I just finished reading his book Biocentrism and I said to myself, ‘Finally, aha, somebody that I can totally relate to.’”, “TIME Magazine: Top 100 Icons of the Century”, “To give us a glimpse about some of the big breakthroughs that were made in biotechnology, we have Dr. Robert Lanza of Advanced Cell Technology. But these nonconceptual representations must play the right functional role in order to be conscious. "Reimers et al have most definitely NOT shown that strong or coherent Frohlich condensation in microtubules is unfeasible. “I downloaded a digital copy of [Biocentrism] in the privacy of my home, where no one could observe my buying or reading such a “New Agey” sort of cosmology book. Levine, J. If it is definitional of consciousness that it is nonfunctional, then holding that the mind is fully functional amounts to a denial of consciousness. For example, it might be reasonable to demand some explanation of how particular neural states correlate with differences in conscious experience. This compatibilism is achieved at the price of consciousness epiphenomenalism, the view that conscious properties can be caused by physical events, but they cannot in turn cause physical events. Found insideThis text originates from the second of two conferences discussing the concept of consciousness. In 15 sections, this book demonstrates the broad range of fields now focusing on consciousness. Because of the subjective differences in these modes of conceptual access, consciousness does not seem intuitively to be physical. But where are they all? Dualistic challenges to this claim will be discussed in later sections. Have you heard of Dr. Stuart Hameroff or Sir Roger Penrose?
