Neglect from bilateral brain injury can disrupt responses along space defined by the vertical and radial axes. The spatial reference frames for vertical and radial neglect remain largely undefined, however. The viewer centred system, for example, consists of retinocentric and cephalocentric/corporacentric frames. In the present study, different viewer centred reference frames were dissociated in a patient with combined far radial superior vertical neglect through performance of radial line bisections above and below eye level. To separate reference frames for vertical space, bisections were performed while the patient was lying sideways. Results suggest that this patient's neglect respected a retinotopic viewer centred reference frame.
双侧脑损伤导致的忽视会干扰沿垂直轴和放射状轴所定义空间的反应。然而，垂直和放射状忽视的空间参照系在很大程度上仍未明确。例如，以观察者为中心的系统由视网膜中心和头/身体中心参照系组成。在本研究中，通过让一名患有远放射状上垂直忽视合并症的患者对高于和低于眼水平的放射状线进行平分，分离出了不同的以观察者为中心的参照系。为了分离垂直空间的参照系，在患者侧卧时进行平分。结果表明，该患者的忽视遵循视网膜定位的以观察者为中心的参照系。
