In the mid-1990s Hameroff teamed with British physicist Sir Roger Penrose to develop the controversial theory of consciousness called “orchestrated objective reduction” – Orch OR theory – in which consciousness derives from quantum computations in microtubules inside brain neurons, quantum computations connected to the fine- scale consciousness and (2) that OR played a key role in life’s evolution. The proposed Orch OR concluded that consciousness plays an intrinsic role in the universe and suggests a connection between brain biomolecular processes and fine-scale structure of the universe. The theory gained little traction in the past because it was difficult to test but Musser thinks that the use of anesthetics on brain organoids (picture above, they are lumps of brain tissue grown in a medium), along Orch OR is quite simply completely impossible; it flies in the face of everything we know about neural function AND quantum mechanics.
