thank you for your excellent summary.
I'm familiar and very supportive of the holonomic brain model.
Where I go, I would suggest, further in the book is to a wholeworld-view of unified reality - where our entire Universe is innately in-formed and holographically manifest - and that
information is reality (with its complementary expressions of energy-matter and space-time as emergent phenomena)
mind is matter
and consciousness isn't something we have but what we and the whole world are.
Within this wholeworld-view of the cosmic hologram,the brain is naturally holonomic.
