 		INFO: Reduction....
The Penrose reduction relation: t=E/hbar

Shadows of the Mind

Quote:
Subjective reduction is what happens when an observer measures a quantity in a quantum system: the system is not in any specific state (the system is in a "superposition" of possible states) until it is observed, the observation causes the system to reduce (or "collapse") to a specific state. This is the only reduction known to traditional Quantum Theory.

Objective reduction is a Penrose discovery, part of his attempt at unifying Relativity Theory and Quantum Theory. Superpositioned states each have their own spacetime geometries. Under special circumstances, which microtubules are suitable for, the separation of spacetime geometry of the superpositioned states (i.e., the "warping" of these space-times) reaches a point (the quantum gravity threshold) where the system must choose one state. The system must then spontaneously and abruptly collapse to that one state.
This "self-collapse" results in particular "conformational states" that regulate neural processes. These conformational states can interact with neighboring states to represent, propagate and process information. Each self-collapse corresponds with a discrete conscious event. Sequences of events then gives rise to a "stream" of consciousness. The proteins somehow "tune" the objective reduction which is thus self-organized, or "orchestrated".
...
In general, the collapse of the wave function is what gives the laws of nature a non-algorithmic element. Otherwise we would simply be machines and we would have no consciousness.
