Object-based neglect for the near peripersonal space in drawing tasks.
We report a patient with a right cortical and subcortical temporo-occipital lesion who showed spatial neglect mainly involving the left and the near peripersonal space. In drawing tasks the patient omitted the elements closer to him within each figure. A copying task with pairs of radially aligned line drawings demonstrated that the patient's radial neglect was based on within-object coordinates. This novel observation extends the egocentric-allocentric distinction to the radial dimension.
