There’s a very interesting event taking place today (Jan. 16, 2014) in Amsterdam, Netherlands titled: NEW PROOF OF REVOLUTIONARY THEORY OF CONSCIOUSNESS (programme).,which is one of a month’s worth of events themed around the brain (The Brainstorming Sessions). The speakers at this event have recently published a paper and a Jan. 16, 2014 news item on ScienceDaily gives some insight into why theirbrainstorming session has the word revolutionary in the title,
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. The recent discovery of quantum vibrations in “microtubules” inside brain neurons corroborates this theory, according to review authors Stuart Hameroff and Sir Roger Penrose. They suggest that EEG rhythms (brain waves) also derive from deeper level microtubule vibrations, and that from a practical standpoint, treating brain microtubule vibrations could benefit a host of mental, neurological, and cognitive conditions.
A Jan. 16, 2014 Elsevier press release,which originated the news item, provides more details about the theory,
The theory, called “orchestrated objective reduction” (‘Orch OR’), was first put forward in the mid-1990s by eminent mathematical physicist Sir Roger Penrose, FRS, Mathematical Institute and Wadham College, University of Oxford, and prominent anesthesiologist Stuart Hameroff, MD, Anesthesiology, Psychology and Center for Consciousness Studies, The University of Arizona, Tucson. They suggested that quantum vibrational computations in microtubules were “orchestrated” (“Orch”) by synaptic inputs and memory stored in microtubules, and terminated by Penrose “objective reduction” (‘OR’), hence “Orch OR.” Microtubules are major components of the cell structural skeleton.
Orch OR was harshly criticized from its inception, as the brain was considered too “warm, wet, and noisy” for seemingly delicate quantum processes. However, evidence has now shown warm quantum coherence in plant photosynthesis, bird brain navigation, our sense of smell, and brain microtubules. The recent discovery of warm temperature quantum vibrations in microtubules inside brain neurons by the research group led by Anirban Bandyopadhyay, PhD, at the National Institute of Material Sciences in Tsukuba, Japan (and now at MIT), corroborates the pair’s theory and suggests that EEG rhythms also derive from deeper level microtubule vibrations. In addition, work from the laboratory of Roderick G. Eckenhoff, MD, at the University of Pennsylvania, suggests that anesthesia, which selectively erases consciousness while sparing non-conscious brain activities, acts via microtubules in brain neurons.
“The origin of consciousness reflects our place in the universe, the nature of our existence. Did consciousness evolve from complex computations among brain neurons, as most scientists assert? Or has consciousness, in some sense, been here all along, as spiritual approaches maintain?” ask Hameroff and Penrose in the current review. “This opens a potential Pandora’s Box, but our theory accommodates both these views, suggesting consciousness derives from quantum vibrations in microtubules, protein polymers inside brain neurons, which both govern neuronal and synaptic function, and connect brain processes to self-organizing processes in the fine scale, ‘proto-conscious’ quantum structure of reality.”
After 20 years of skeptical criticism, “the evidence now clearly supports Orch OR,” continue Hameroff and Penrose. “Our new paper updates the evidence, clarifies Orch OR quantum bits, or “qubits,” as helical pathways in microtubule lattices, rebuts critics, and reviews 20 testable predictions of Orch OR published in 1998 – of these, six are confirmed and none refuted.”
An important new facet of the theory is introduced. Microtubule quantum vibrations (e.g. in megahertz) appear to interfere and produce much slower EEG “beat frequencies.” Despite a century of clinical use, the underlying origins of EEG rhythms have remained a mystery. Clinical trials of brief brain stimulation aimed at microtubule resonances with megahertz mechanical vibrations using transcranial ultrasound have shown reported improvements in mood, and may prove useful against Alzheimer’s disease and brain injury in the future.
Lead author Stuart Hameroff concludes, “Orch OR is the most rigorous, comprehensive and successfully-tested theory of consciousness ever put forth. From a practical standpoint, treating brain microtubule vibrations could benefit a host of mental, neurological, and cognitive conditions.
The review is accompanied by eight commentaries from outside authorities, including an Australian group of Orch OR arch-skeptics. To all, Hameroff and Penrose respond robustly.
The press release ends with this information about the event in Amsterdam,
Penrose, Hameroff and Bandyopadhyay will explore their theories during a session on “Microtubules and the Big Consciousness Debate” at the Brainstorm Sessions, a public three-day event at the Brakke Grond in Amsterdam, the Netherlands, January 16-18, 2014. They will engage skeptics in a debate on the nature of consciousness, and Bandyopadhyay and his team will couple microtubule vibrations from active neurons to play Indian musical instruments. “Consciousness depends on anharmonic vibrations of microtubules inside neurons, similar to certain kinds of Indian music, but unlike Western music which is harmonic,” Hameroff explains.
I wasn’t able to locate information about the three-day event in the press release but I did find this about the month-long series, The Brainstorm Sessions (Dutch language first, scroll down for English language version),
Europe and the USA are looking to completely unravel the secrets of our brains within the next ten years. Europe has designated 2014 as The Year of the Brain. We have decided to dedicate a month to the grey matter. A month in which guest curator Frank Theys – filmmaker, philosopher and visual artist – i.c.w. Damiaan Denys (neuroscientist, philosopher and professor of psychiatry at the AMC-UvA, the Amsterdam Medical Centre of the University of Amsterdam) will bring together elements he considers interesting from an artistic and philosophical viewpoint related to this theme.
Featuring an exhibition at the intersection between artistic and scientific experiments; the first ever performance by ‘stand-up scientist’ Damiaan Denys, Head of Psychiatry at the AMC hospital; a ‘neuro-concert’ by nanoscientist Anirban Bandyopadyay and a film programme in the Kriterion cinema in cooperation with Patricia Pisters, author of The Neuro-Image.

I’m not sure what your chances are for attending the events on Jan. 17 or Jan. 18 but I wish you good luck! For those of us who weren’t able to attend the Jan.16, 2014 event featuring Penrose amd Hameroff, there are recently published papers.
First, the researchers offer a review of their theory along with some refinements,
