Focal cerebral blood flow changes for judgment of line orientation were determined using the 133Xe inhalation technique with 18 normal right-handed male subjects. Measurements were made during three conditions in the same session: a line orientation task, a sensorimotor control task, and normal rest. Blood flow changes attributable to the judgment of line orientation were found for the measure f1 at a detector centered over the right temporo-occipital region. For the measure IS this activation was significant in the temporo-occipital region in both hemispheres but significantly greater in the right hemisphere. For f1 the change in blood flow and for IS the percent change in blood flow in the right temporo-occipital region attributable to judgment of line orientation decreased as performance on the line orientation task improved.
使用吸入¹³³Xe技术，对18名正常右利手男性受试者进行了局灶性脑血流变化测定，以判断线条方向。在同一次实验中，于三种条件下进行测量：线条方向任务、感觉运动控制任务和正常休息。在位于右颞枕区上方的一个探测器处，发现测量指标f1存在归因于线条方向判断的血流变化。对于测量指标IS，这种激活在双侧颞枕区均显著，但在右半球更为显著。对于f1，右颞枕区归因于线条方向判断的血流变化，以及对于IS，该区域血流的百分比变化，均随着线条方向任务表现的改善而降低。
