Anesthesiologist · Quantum consciousness theorist & researcher
Stuart Hameroff, MD
A clinical anesthesiologist and researcher on how the brain produces consciousness — and how anesthetics act to erase it.
In the mid-1990s he teamed with Sir Roger Penrose to develop the controversial Orch OR theory, in which consciousness arises from “orchestrated” quantum vibrations in microtubules, tied to the fine-scale structure of spacetime through Penrose’s “objective reduction.”
