To study the distributions and the neural correlates of left hemispatial neglect with different reference frames.
Data were collected from patients with right brain injury who participated in a case series.
Hospital departments of rehabilitation and neurology.
Right brain-damaged patients (N=110).
Not applicable.
The frequency of left hemispatial neglect with different reference frames was investigated, and the respective brain lesions were displayed and analyzed.
Not all subjects finished predesigned neglect tests because of their condition: 8 of the 55 neglect patients were unable to complete the test for classification. Thirty (63.83%) of 47 subjects with neglect displayed both allocentric and egocentric neglect, while 17 subjects showed pure egocentric neglect. The lesions in the inferior frontal gyrus, precentral gyrus, postcentral gyrus, superior temporal gyrus (STG), middle temporal gyrus (MTG), insula, and surrounding white matters were more frequent in the neglect group than in the control group. Compared with the egocentric neglect group, the lesions in the right STG, MTG, lenticular nucleus, and the surrounding white matter were damaged more frequently in the group displaying both allocentric and egocentric neglect.
More than half of the subjects with left neglect after right brain injury have both egocentric and allocentric neglect. The right inferior frontal gyrus, precentral gyrus, postcentral gyrus, STG, MTG, insula, and the surrounding white matter are associated with left hemispatial neglect. Left allocentric neglect is associated with the right STG, MTG, and lenticular nucleus.
研究不同参照系下左侧空间忽略的分布及其神经相关性。

研究不同参照系下左侧空间忽略的频率，并显示和分析各自的脑损伤。
并非所有患者都能完成预定的忽略测试，因为他们的病情：55 名忽略患者中有 8 人无法完成分类测试。47 名有忽略的患者中有 30 名（63.83%）表现出了定向和自我中心忽略，而 17 名患者表现出了单纯的自我中心忽略。在忽略组中，下额回、中央前回、中央后回、颞上回（STG）、颞中回（MTG）、岛叶和周围白质的损伤比对照组更常见。与单纯自我中心忽略组相比，同时表现出定向和自我中心忽略的患者中，右侧 STG、MTG、豆状核和周围白质的损伤更频繁。
右脑损伤后有超过一半的左侧忽略患者同时存在自我中心和定向忽略。右侧下额回、中央前回、中央后回、STG、MTG、岛叶和周围白质与左侧空间忽略有关。左侧定向忽略与右侧 STG、MTG 和豆状核有关。
