the neurobiology of conscious minds has been based on combining three perspectives: (1) the direct-witness perspective on the individual conscious mind, which is personal, private, and unique to each one of us; (2) the behavioral perspective, which allows us to observe the telltale actions of others whom we have reason to believe also have conscious minds; and (3) the brain perspective, which allows us to study certain aspects of brain function in individuals whose conscious mind states are presumed to be either present or absent.
