Abstract
Clinical aspects and neuropsychological mechanisms of anosognosias in the broad sense were mentioned : anosognosia in (1) Anton syndrome, (2) Wernicke aphasia, (3) anterograde amnesia and (4) denial of left hemiplegia (Anosognosia of type Babinski). We considered anosognosia of Babinski as the result of impaiment of “body consciousness”. Body Schema and Body Consciousness were distinguished along Edelman's hypothesis. The former might belong to Higher Order Consciousness and have symbolic nature. The latter belonging to Primary Consciousness might have immediate, non-symbolic nature. The author stressed the idea that if body consciousness would be represented predominantly by right hemisphere, namely bilateral body would be represented by right hemisphere and right side body by left hemisphere, we could explain ingeniously the phenomena of “denial of left hemiplegia” (anosognosia of type Babinski) and somatoparaphrenia described by Gerstmann.
