Plants have microtubules and their phototropism is inhibited by anesthesia. They probably have ten conscious moments per minute. We have 10,000,000 per second.

Do plants have minds? Can we see past our soul-blindness to recognise plant minds? In the 1840s, the iconoclastic scientist Gustav Fechner made an inspired case for taking seriously the interior lives of plants (via @aeonmag )

Absurd. Dave says we don’t know how the brain produces consciousness, therefore AI will definitely be conscious. He can’t be serious. The brain’s not just a machine Dave, it’s 1) alive, 2) hierarchically fractal, 3) quantum, 4) dependent on microtubules acting as time crystals.

@StuartHameroff When we say “MT are quantum structures”, what’s meant by this experimentally? What’s the falsifiable observable that we look for in experiment to confirm that MT “exhibit quantum behavior”? What do we mean when we say quantum behavior in this context?

@StuartHameroff Since animals, even reptiles, can be anesthesized does that imply that consciousness is ubiquitous in life? What about insects and birds? Germs? Does the same frequency hierarchy in MTs exist in other animals?

Closer than any other theory. Orch OR quantum/classical transition or collapse can vary with frequency, and thus maybe different Koshas. Faster than terahertz might be transcendent, or quantum super-radiant. Then non-local. The deeper you go, the higher you fly. (Beatles)
