Abstract: Contends that if the commissural-integrative conception (e.g., R. W. Sperry, published 1966-1982) of the normal stream of consciousness is correct, then the consciousness of the deconnected left hemisphere is not a normal consciousness, because the right hemisphere cannot contribute to the left hemisphere's stream except by means of inadequate subcortical connections. Three hypothesized dimensions of deconnected left-hemispheric consciousness are considered: (1) Is the deconnected left hemisphere alienated as agent from behavior produced by the respective right hemisphere? (2) Is the stream of consciousness of the deconnected left hemisphere more narrow and more disunified than the normal stream? (3) Is the deconnected left hemisphere unaware of the commissurotomy-produced deficiencies characterizing its stream of consciousness? These questions represent natural directions in which to investigate the distinctiveness of left-hemispheric consciousness. ((c) 1999 APA/PsycINFO, all rights reserved)
