Abstract
The subjective location of the mid-sagittal plane was assessed by a free-field auditory localization task in the front and in the back half-spaces in 11 right brain-damaged patients with spatial hemineglect, 10 right brain-damaged patients without spatial hemineglect, and 11 normal control subjects. In patients with hemineglect the subjective mid-sagittal plane was found to be displaced rightwards in both half-spaces. Both patients without hemineglect and controls, in contrast, made a minor error and showed a greater displacement cowards the left side in the back half-space. In four right brain-damaged patients the rightward displacement was confined either to the front, or to the back half-space. This pattern of impairment may be explained by a rightward, ipsilesional, pathological translation of an egocentric coordinate system, rather than by a rotation around the vertical axis of the body.
