It is precisely because the electromagnetic field isn’t physical that it can observe. If the physical world is a virtual reality, the quantum reality that created it must be able to observe it. Quantum theory requires quantum entities to observe when they interact but these infinitesimal observations are to us proto-consciousness, not the consciousness we know.
That would be the end of it but when quantum entities entangle, they merge and act as one. When photons entangle in physics, the ensemble instantly knows what happens to either, even if they are too far apart to exchange data physically. This isn’t information exchange but it has the same effect, so when nerve units entangle by synchrony, the ensemble can collapse to observe any unit combination at any field point. Distant neural areas don’t exchange information by wiring but by forming a common quantum observer. Applying Penrose’s logic to nerves, if synchronized firing can entangle molecules to observe as one, it can entangle nerves to do the same, and we call the result consciousness. The observer is in the electromagnetic field the brain creates but it isn’t physical.
It isn’t proposed that all the brain’s nerves synchronize but that local synchronies let nerves entangle to solve local problems, allowing an evolution from microcolumns to macrocolumns and so on, step-by-step. Nor is it required that all nerves synchronize perfectly, as only some need to do so to achieve the effect. Just as nerves that wire together fire together, so nerves that fire together observe together. What we call consciousness is nerves using synchrony to merge local observations into a global observation.
A neuron that observes when it fires is like a closed window that opens for a moment and neurons firing in synchrony open a bigger observation window. The brain’s answer to the binding problem was to use neural synchrony to create consciousness, hence:
1. Consciousness takes time. Neural synchronies take time to form.
2. Consciousness scales. Synchrony applies at multiple scales of brain activity.
3. Consciousness cascades. Small-scale synchronies lead to large-scale synchronies.
