[The Laterality of Parietal Association Areas: Hemispatial Neglect, Body Images and Body Schema].

This paper discusses the laterality of parietal association areas, focusing on hemispatial neglect and body representation. Extra-personal spatial neglect can be severe and is frequently observed following right parietal lesions; personal neglect is also common with right parietal lesions. According to the frame of awareness and perception, I speculate that the awareness of space is related to hemispatial neglect of extra-personal space, and awareness of body is related to personal neglect. Both clinical symptoms are common with right parietal lesions. On the other hand, I speculate that the perception of body is related to autotopagnosia, which could be associated with left parietal lesions.
