  Other physical theories have gone beyond the neural and placed the natural locus of consciousness at a far more fundamental level, in particular at the micro-physical level of quantum phenomena. According to such theories, the nature and basis of consciousness can not be adequately understood within the framework of classical physics but must be sought within the alternative picture of physical reality provided by quantum mechanics. The proponents of the quantum consciousness approach regard the radically alternative and often counterintuitive nature of quantum physics as just what is needed to overcome the supposed explanatory obstacles that confront more standard attempts to bridge the psycho-physical gap.
