Consciousness is considered as a fundamental property of the universe in quantum theories of consciousness. We consider our physical universe as appeared by the phase-like transition of the energy waves, unfolded from 10 dimensions. The human brain and its mental aspects are associated with classical brain physiology and are also part of a quantum physical universe. We consider the whole universe being multi-dimensional, of (4 + D)-dimensional Friedmann-Robertson-Walker-type (FRW), with complex

... scale factor "R + i RI", where "R" is the scale factor corresponding to the usual 4-dimensional universe, and "i RI" is that of D-dimensional space-time. It is found that for D = 6 (i.e. in 10 dimensions), the Wheeler-DeWitt equation is symmetric under the exchange RI ↔ R. Mathematically, when D = 6, it is RI = R and the physical universe starts. The universe starts with the symmetry breaking of group SU(11). We assume that the extra-dimensions "D" are associated with a mental-consciousness or that of the individual mind-consciousness is (partly) an expression of a universal mind-consciousness through holonomic communication with quantum fields. "Consciousness" is created by the electromagnetic force in the framework of SU(6) ´U(1), whereas "mind" is created by the framework of SU(2) ´ U(1). The human brain is conceived as an interfacing organ that not only produces mind and consciousness, but also receives information. The brain or parts of it are conceived as an "interference hologram" of incoming data and already existing ones (a "personal universe"), equivalent to the subject's memory. If properly analyzed, information about the outer world can be distilled, with the analyzer being cerebral electrophysiology.
