Effect of head-centered and body-centered hemispace in unilateral neglect.
The aim of this study was to evaluate the effects of head-centered and body-centered hemispace on a line bisection task in patients with left unilateral neglect. Five patients with left unilateral neglect were given a line bisection task under four different conditions. The results clearly demonstrate that both head-centered and body-centered hemispace had a statistically significant effect on the line bisection task. The results are discussed with respect to a reference frame of space and the validity of dividing unilateral neglect into two components (i.e., spatial neglect and object neglect) is proposed.
