  If conscious observers are to be included in the quantum mechanical universe,
we need to find the rules that engage observers with quantum mechanical
systems. The author has proposed five rules that are discovered by insisting on
empirical completeness; that is, by requiring the rules to draw empirical
information from Schrodinger's solutions that is more complete than is
currently possible with the (Born) probability interpretation. I discard Born's
interpretation, introducing probability solely through probability current.
These rules tell us something about brains. They require the existence of
observer brain states that are neither conscious nor unconscious. I call them
'ready' brain states because they are on stand-by, ready to become conscious
the moment they are stochastically chosen. Two of the rules are selection rules
involving ready brain states. The place of these rules in a wider theoretical
context is discussed. Key Words: boundary conditions, consciousness,
decoherence, macroscopic superposition, Penrose, state reduction, von Neumann,
wave collapse.
