Roger Penrose talked about this with Lex Fridman. The anesthesiologist Stuart Hameroff is looking into how anesthesia affects microtubules and the implications for consciousness. Penrose is intrigued by the symmetry of microtubules and the possibility for this symmetry to enable quantum coherence to be accessible biologically. His larger point is that consciousness is not a computation. https://youtu.be/hXgqik6HXc0 https://youtu.be/hXgqik6HXc0 Relevant part starts around 3:30.
