Mind Matters

At New Scientist last week, science writer and editor George Musser talked about the way a theory of consciousness that sees the brain as a quantum system is now under reluctant consideration. Musser, author of Putting Ourselves Back in the Equation (Farrar, Straus and Giroux, 2023) went to visit anesthesiologist Stuart Hameroff, who — with theoretical physicist Roger Penrose — advances the quantum-based Orch Or Theory (orchestrated objective reduction of the quantum state).
Do quantum phenomena create conscious experience?
Musser explains the basic idea of the Orch Or Theory (OOT), that conscious experience arises from quantum phenomena in the brain. 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 (lumps of brain tissue grown in a medium), along with other new methods may enable the theory to be tested:
