theoretical basis

• P- Sperry's work prompted a theoretical and philosophical debate about the degree of communication between the two hemispheres in everyday functioning and the nature of consciousness
• E- some theorists, for example Roland Pucetti (1977) have suggested that the two hemispheres are so functionally different that they represent a form of duality in the brain- that in effect we are all two minds (and that this situation is only emphasised rather than created in the split-brain patients)
• L- in contras, other researchers have argued that, far from working in isolation, that two hemispheres form a highly integrated system and are both involved in most everyday tasks
