The sum of their main ideas: Consciousness has multiple facets. The two hemispheres can have different states of consciousness. The right hemisphere has more limited cognitive capacities than the left one, but however should be invested with some respectability, cause it is more than an automaton, demonstrating a variety of complex cognitive abilities as exhibition of goal-directed behavior, formulating some basic hypotheses regarding the relation of its actions to the world, the desire to cooperate with the experimenter in experimental tasks.
        Separation of the two hemispheres shows some cognitive function losses (e.g. writing performace, memory performence) that confirm the principle that the whole is more than the sum of its parts; that is, some cognitive tasks implies the unidirectional or bidirectional communication between different systems, that are not present in both hemispheres, from both hemispheres. The left hemisphere is the dominant one. The the loss of communication between hemispheres does not prevent the maintenace of an independent sense of self.
        The brain has modules that operate largely outside the realm of awareness and of which computational products are sent to various executive systems that result in behavior or cognitive states. There are multiple executive systems that can have selective influence over behavior. The left hemisphere has an interpreter module that manages and interpretes all constant and parallel activities, both those that origined in it and those that are not origined in it.
