Indeed, there are many definitions of consciousness and multiple approaches to study the neural correlates of consciousness (NCC). Therefore, the main aim of this article is to collect data on the various theories of consciousness published between 2007–2017 and to synthesize them to provide a general overview of this topic. To describe each theory, we developed a thematic grid called the dimensional model, which qualitatively and quantitatively analyzes how each article, related to one specific theory, debates/analyzes a specific issue. -
Mind Byte” Series Disperses Particles from the Consciousness Documentary “The Deeper You Go”
STORY LLC CONTACT 11TH STORY LLC FOR IMMEDIATE RELEASE Tel: 414.301.1102 or 2 [email protected] November 4, 2014 “MIND BYTE” SERIES DISPERSES PARTICLES FROM THE CONSCIOUSNESS DOCUMENTARY “THE DEEPER YOU GO” “Mind Byte” an ongoing series of one minute interview clips to promote the 2015 release of “The Deeper You Go” launched with controversial biologist Rupert Sheldrake. In “The Deeper You Go” Milwaukee filmmakers Lora Nigro and Kevin Rutkowski, reunited with Los Angeles cinematographer Vincent Gaudes, interviewed keynote speakers on the fly at The Toward a Science of Consciousness Conference organized and sponsored by The Center for Consciousness Studies; University of Arizona this April. Setting up camp in the hotel courtyard where the conference was held, they shot guerilla style with one HD camcorder and boom microphone but seized a hotel storage closet for the makeshift indoor shots. Known luminaries and TED talkers Deepak Chopra, Susan Blackmore, David Chalmers, Dan Dennett, Stuart Hameroff, John Searle, Stanislas Dehaene and NY Times best selling author Eben Alexander, Proof of Heaven are among the rock star line up. The Sneak Preview demo introduced this September captured the ensuing debate in quick point-counter point edits, suggesting that the sharpest minds in the field don’t agree much on the nature of mind. “Consciousness” the film’s featured soundtrack single also became available web-wide. Nigro and Rutkowski’s background as recording artists, whose lyrical explorations of the meaning of existence, provides a context for their interest in the subject. Consciousness is fundamental to our reality. Once the domain of religion, the study of human consciousness has exploded in the last decades, making headway in the fields of neuroscience, psychology, philosophy and other disciplines. -

Hameroff,* and Roger Penrose† * Anesthesiology and Psychology, Center for Consciousness Studies, Banner-University Medical Center The University of Arizona, Tucson, Arizona, USA † Mathematical Institute and Wadham College, University of Oxford, Oxford, UK Abstract The nature of consciousness, the mechanism by which it occurs in the brain, and its ultimate place in the universe are unknown. We proposed in the mid 1990’s that consciousness depends on biologically “orchestrated” coherent quantum processes in collections of microtubules within brain neurons, that these quantum processes correlate with, and regulate, neuronal synaptic and membrane activity, and that the continuous Schrödinger evolution of each such process terminates in accordance with the specific Diósi–Penrose (DP) scheme of “ objective reduction” (“OR”) of the quantum state. This orchestrated OR activity (“Orch OR”) is taken to result in moments of conscious awareness and/or choice. The DP form of OR is related to the fundamentals of quantum mechanics and space–time geometry, so Orch OR suggests that there is a connection between the brain’s biomolecular processes and the basic structure of the universe. Here we review Orch OR in light of criticisms and developments in quantum biology, neuroscience, physics and cosmology. We also introduce novel suggestions of (1) beat frequencies of faster Orch OR microtubule dynamics (e.g. megahertz) as a possible source 517 bb2237_Ch-14.indd2237_Ch-14.indd 551717 44/15/2016/15/2016 112:31:372:31:37 PPMM FA b2237 Biophysics of Consciousness: A Foundational Approach “9x6” 518 S. -
"Orchestrated Objective Reduction"(Orch OR)
Orchestrated Objective Reduction of Quantum Coherence in Brain Microtubules: The "Orch OR" Model for Consciousness Stuart Hameroff & Roger Penrose, In: Toward a Science of Consciousness - The First Tucson Discussions and Debates, eds. Hameroff, S.R., Kaszniak, A.W. and Scott, A.C., Cambridge, MA: MIT Press, pp. 507-540 (1996) Stuart Hameroff and Roger Penrose ABSTRACT Features of consciousness difficult to understand in terms of conventional neuroscience have evoked application of quantum theory, which describes the fundamental behavior of matter and energy. In this paper we propose that aspects of quantum theory (e.g. 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 the brain's neurons. The particular characteristics of microtubules suitable for quantum effects include their crystal-like lattice structure, hollow inner core, organization of cell function and capacity for information processing. We envisage that conformational states of microtubule subunits (tubulins) are coupled to internal quantum events, and cooperatively interact (compute) with other tubulins. We further assume that macroscopic coherent superposition of quantum-coupled tubulin conformational states occurs throughout significant brain volumes and provides the global binding essential to consciousness. We equate the emergence of the microtubule quantum coherence with pre-conscious processing which grows (for up to 500 milliseconds) until the mass-energy difference among the separated states of tubulins reaches a threshold related to quantum gravity. According to the arguments for OR put forth in Penrose (1994), superpositioned states each have their own space-time geometries. -
Chapter 5 the "Quantum Soul": a Scientific Hypothesis
Chapter 5 The "Quantum Soul": A Scientific Hypothesis Stuart Hameroff and Deepak Chopra Abstract The concept of consCiousness existing outside the body (e.g. near-death and out-of body experiences, NDE/OBEs, or after death, indicative of a 'soul') is a staple of religious traditions, but shunned by conventional science because of an apparent lack of rational explanation. However conventional science based entirely on classical physics cannot account for normal in-the-brain consciousness. The Penrose-Hameroff 'Orch OR' model is a quantum approach to consciousness, con necting brain processes (microtubule quantum computations inside neurons) to fluctuations in fundamental spacetime geometry, the fine scale structure of the uni verse. Recent evidence for significant quantum coherence in warm biological sys tems, scale-free dynamics and end-of-life brain activity support the notion of a quantum basis for consciousness which could conceivably exist independent of biology in various scalar planes in spacetime geometry. Sir Roger Penrose does not necessarily endorse such proposals which relate to his ideas in physics. Based on Orch OR, we offer a scientific hypothesis for a 'quantum soul'. 5.1 Brain, Mind, and Near-Death Experiences The idea that conscious awareness can exist after bodily death, generally referred to as the "soul," has been inherent in Eastern and Western religions for thousands of years. In some traditions, memories and awareness may be transferred after death to other lifetimes: reincarnation. In addition to beliefs based on religion, innumerable S.

6 Consciousness, Neurobiology and Quantum Mechanics: the Case for a Connection
6 Consciousness, Neurobiology and Quantum Mechanics: The Case for a Connection Stuart Hameroff Summary. Consciousness is generally considered to emerge from synaptic com- putation among brain neurons, but this approach cannot account for its critical features. The Penrose–Hameroff “Orch OR” model suggests that consciousness is a sequence of quantum computations in microtubules within brain neurons, shielded from decoherence to reach threshold for objective reduction (OR), the Penrose quantum gravity solution to the measurement problem. The quantum computations are “orchestrated” by neuronal/synaptic inputs (hence “Orch OR”), and extend throughout cortex by tunneling through gap junctions. Each Orch OR is proposed as a conscious event, akin to Whitehead’s philosophical “occasion of experience”, occurring in concert with brain electrophysiology. This chapter discusses the need for such an approach and its neurobiological requirements. 6.1 Introduction: The Problems of Consciousness Consciousness involves phenomenal experience, self-awareness, feelings, choices, control of actions, a model of the world, etc. But what is it? Is con- sciousness something specific, or merely a byproduct of information process- ing? Whatever it is, consciousness is a multifaceted puzzle. Despite enormous strides in behavioral and brain science, essential features of consciousness continue to elude explanation. Unresolved problems include: 1. Neural correlates of conscious perception apparently occur too late – 150 to 500 milliseconds (ms) after impingement on our sense organs – to have causal efficacy in seemingly conscious perceptions and willful actions, often initiated or completed within 100 ms after sensory impingement. For example, in the color phi and cutaneous rabbit anomalies, the brain apparently fills in conscious sensory information that is not yet avail- able [130, 71, 40]. -
Neuroscience, Quantum Space-Time Geometry and Orch OR Theory
Journal of Cosmology, 2011, Vol. 14. JournalofCosmology.com, 2011 Consciousness in the Universe: Neuroscience, Quantum Space-Time Geometry and Orch OR Theory Roger Penrose, PhD, OM, FRS1, and Stuart Hameroff, MD2 1Emeritus Rouse Ball Professor, Mathematical Institute, Emeritus Fellow, Wadham College, University of Oxford, Oxford, UK 2Professor, Anesthesiology and Psychology, Director, Center for Consciousness Studies, The University of Arizona, Tucson, Arizona, USA Abstract The nature of consciousness, its occurrence in the brain, and its ultimate place in the universe are unknown. We proposed in the mid 1990's that consciousness depends on biologically 'orchestrated' quantum computations in collections of microtubules within brain neurons, that these quantum computations correlate with and regulate neuronal activity, and that the continuous Schrödinger evolution of each quantum computation terminates in accordance with the specific Diósi–Penrose (DP) scheme of 'objective reduction' of the quantum state (OR). This orchestrated OR activity (Orch OR) is taken to result in a moment of conscious awareness and/or choice. This particular (DP) form of OR is taken to be a quantum-gravity process related to the fundamentals of spacetime geometry, so Orch OR suggests a connection between brain biomolecular processes and fine-scale structure of the universe. Here we review and update Orch OR in light of criticisms and developments in quantum biology, neuroscience, physics and cosmology. We conclude that consciousness plays an intrinsic role in the universe. KEY WORDS: Consciousness, microtubules, OR, Orch OR, quantum computation, quantum gravity 1. Introduction: Consciousness, Brain and Evolution Consciousness implies awareness: subjective experience of internal and external phenomenal worlds. Consciousness is central also to understanding, meaning and volitional choice with the experience of free will. -

Discursive Deep Structure and Philosophy of Mind
DISCURSIVE DEEP STRUCTURE AND PHILOSOPHY OF MIND A CRITIQUE OF PATRICIA CHURCHLAND’S NEUROPHILOSOPHY PIETER REPKO. M.B. Ch.B. M.Med. (neurosurgery). Dissertation submitted in fulfilment of requirements for the Master’s Degree in the Faculty of Humanities, Department of philosophy, University of the Free State. The question of how the brain represents its world, both inner and outer, has traditionally been construed as a philosophical question through and through, posed not in terms of the brain but the mind, and addressable not experimentally, but from the comfort of the proverbial armchair. Part of what is exciting about this epoch in science is that both of these assumptions have gradually lost their stuffing, and experimental science – the mix of ethology, psychology, and neuroscience – continues to press forward with empirical techniques for putting the crimp on these ancient questions. A corner that many philosophers thought was utterly unturnable has in fact been turned, if not in popular philosophy, then certainly within the mind/brain sciences.

Physics of Consciousness: David Chalmers Source URL: https://www.closertotruth.com/interviews/54806 Transcript - Long Robert Lawrence Kuhn: Dave, when you started on this rather magnificent journey in trying to explore consciousness, seeing it as fundamental, the hard problem, that was pretty much what your vision was, that there was something special here. And in the intervening couple of decades or more, people have been moving in on your territory, which you're probably pretty happy about, but physicists, in general, or approaches that come from physics or quantum physics have been seeking to explain, whether it's quantum physics mechanisms or consciousness being part of quantum physics or integrated information theory. There are a whole bunch of things that are now coming in, so how do you analyze the physics of consciousness, particularly quantum physics? David Chalmers: Yeah, there are a whole lot of at least potentially intriguing connections between physics and consciousness, and especially quantum mechanics. This is tied partly to the idea that traditional formulations of quantum mechanics seem to give a role to measurement or observation and, well, what is that? It's like, well, the natural hypothesis is that measurement or observation is conscious perception. It's somehow a role of a conscious observer, so that's extremely suggestive for connecting the two, but you can connect them in a lot of ways. Some people might try to reductionistically explain consciousness in terms of quantum mechanical processes. In my view, that works no better than explaining it in terms of classical processes. But another thing you might do is try to, not try to reduce consciousness, but find roles for consciousness in quantum mechanics.
