Replytocriticismofthe‘OrchORqubit’–‘Orchestratedobjectivereduction’isscientificallyjustified

The critical commentary by Reimers et al. [1] regarding the Penrose–Hameroff theory of ‘orchestrated objective reduction’ (‘Orch OR’) is largely uninformed and basically incorrect, as they solely criticize non-existent features of Orch OR, and ignore (1) actual Orch OR features, (2) supportive evidence, and (3) previous answers to their objections (Section 5.6 in our review [2]). Here we respond point-by-point to the issues they raise.

Reimers et al.
… For quantum information processing one must have quantum information storage units such as qubits … the involvement of quantum gravity in the manifestation of consciousness would need to be described in terms of how quantum gravity affected the operation of these qubits …

Consciousness in the universe: A review of the ‘Orch OR’ theory

See on Scoop.itBounded Rationality and Beyond

Abstract

The nature of consciousness, the mechanism by which it occurs in the brain, and its ultimate place in the universe are un- known. 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, neu- roscience, physics and cosmology. We also introduce a novel suggestion of ‘beat frequencies’ of faster microtubule vibrations as a possible source of the observed electro-encephalographic (‘EEG’) correlates of consciousness. We conclude that consciousness plays an intrinsic role in the universe.

Sir Roger Penrose — The quantum nature of consciousness – YouTube

https://www.youtube.com/v/3WXTX0IUaOg?fs=1&hl=fr_FR

Sir Roger Penrose. Quantum Consciousness Theorist — Co-creator of the Orch OR model of the quantum nature of consciousness and memory. http://GF2045.com/speakers/

Knighted in 1994 for his contributions to science, Sir Roger Penrose OM FRS, is an English mathematical physicist, mathematician and philosopher.

The extraordinary scope of his work ranges from quantum physics and theories of human consciousness to relativity theory and observations on the structure of the universe. Penrose is internationally renowned for his scientific work in mathematical physics, in particular for his contributions to general relativity and cosmology. His primary interest is in a field of geometry called tesselation, the covering of surfaces with tiles of different shapes.

Among numerous prizes and awards, he received the 1988 Wolf Prize for physics, which he shared with Stephen Hawking for their contribution to our understanding of the universe.

He is the Emeritus Rouse Ball Professor of Mathematics at the Mathematical Institute of the University of Oxford, as well as an Emeritus Fellow of Wadham College.

“There is a current view that consciousness is something which arises from some complicated computation. So we have our computers, and people think that because they can do things amazingly fast, and they can calculate very quickly, and they can play chess extremely well, that they are superior to us even, and it is only some complicated aspect of this computational activity that somehow consciousness arises from that. Now my view is quite different from this. I think there is a lot of computational activity going on in the brain, but this is basically unconscious. So consciousness seems to me to be something quite different.”

The science behind how brains process logos

See on Scoop.itBounded Rationality and Beyond
How a brain processes a logo

Because you’re a professional, you know that your logo is the most important first impression you make, especially in a digital world, but do you know how the brain’s visual cortex interacts with that image, and how many milliseconds it takes to process?

No? You’re not alone. Knowing the science behind how the brain “sees” a logo can help to make sure you’re putting your best foot forward.
