"...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."
In a near death experience the microtubules lose their quantum state
"It appears that our experience of consciousness is the result of quantum gravity effects in these microtubules, a theory which they dubbed orchestrated objective reduction (Orch-OR), which has been heavily criticised and remains controversial among other scientists."
"According to the new insights, consciousness is a program for a quantum computer in the brain which can persist in the universe even after death, explaining the perceptions of those who have near-death experiences."
