ABSTRACT
As is known, Wernicke defined three principal areas of psychic experience: corporality, external world, and personality. That this classification is still of major importance, especially in regard to the problem of delusions in schizophrenia, has been indicated by us recently within the framework of a general discussion of the body-mind problem (1). If one pursues the question of which patho-physiological mechanisms can blur the borders between the three areas defined by Wernicke, it is hardly possible to start from schizophrenia. However, partial answers to the question can perhaps be obtained if one examines certain phenomena appearing with localized cerebral affections. These phenomena may be identified collectively as transformations between body image and external world.
