The Orch in Orch-OR stands for orchestrated to give the full name of the theory Orchestrated Objective Reduction.

With reference to this question, a paper by the physicist, Max Tegmark, refuting the Orch-OR model and published in the journal, Physical Review E is widely quoted.

in Nature does indicate quantum coherent electrons as being functional in energy transfer within photosynthetic organisms, but the quantum coherence described lasts for 660 fs rather than the 25 milliseconds required by Orch-OR, and this is compatible with Tegmark's calculations.

Hameroff, however, claims that 8 MHz coherence is sufficient to support the Orch-OR proposal.

The Orch-OR theory is generally discredited among neuroscientists.

Notable theories falling into this category include the Holonomic brain theory of Karl Pribram and David Bohm, and the Orch-OR theory formulated by Stuart Hameroff and Roger Penrose.

In their controversial Orch-OR theory of consciousness, Roger Penrose and Stuart Hameroff postulate that microtubules in neurons conduct quantum-level manipulations of matter, which produces consciousness, based partially on some observations of Gamma Synchrony that indicate that information may propagate through the brain much faster than a chemically mediated neural network would physically permit.

Penrose and Hameroff initially developed their ideas quite separately from one another, and it was only in the 1990s that they cooperated to produce the Orch-OR theory.

The Orch-OR theory arose from the cooperation of these two scientists, and was developed in Penrose's second consciousness book Shadows of the Mind ( 1994 ).

The Orch-OR theory combines Penrose's hypothesis with respect to the Gödel theorem with Hameroff's hypothesis with respect to microtubules.

As a result, Hameroff's group claimed a decoherence time seven orders of magnitude greater than Tegmark's, but still well short of the 25 ms required if the quantum processing in the theory was to be linked to the 40 Hz gamma synchrony, as Orch-OR suggested.

Orch-OR combines approaches to the problem of consciousness from the radically different angles of mathematics, physics and anesthesia.

In their reply to Tegmark's paper, also published in Physical Review E, the physicists Scott Hagan, Jack Tuszynski and Hameroff claimed that Tegmark did not address the Orch-OR model, but instead a model of his own construction.

This involved superpositions of quanta separated by 24 nm rather than the much smaller separations stipulated for Orch-OR.

The Reimers paper claimed that microtubules could only support ' weak ' 8 MHz coherence, but that the Orch-OR proposals required a higher rate of coherence.

In this update, however, he acknowledges the possibility of Penrose-Hameroff Microtubule quantum processing ( Orch-OR ) and states that if his calculations of the processing capability of the brain are off by a factor of a billion, the double-exponential growth of technology will still catch up to it twenty-four years after his original projections.

In the Request for Further Information procedure, use of standard pre-printed forms is not common, and any such request would almost certainly be looked upon critically by the courts, as use of standard forms rather than requests tailored specifically to the case is likely to offend against the ' Overriding Objective ' in that it is unlikely to be proportionate to the case, and instead result in the parties or their lawyers having to spend time, money and resources in answering the questions.
