Abstract

Motor neglect is characterised by an underutilisation of one side, without defects of strength, reflexes or sensibility. Twenty cases of frontal, parietal and thalamic lesions causing motor neglect, but all without sensory neglect, are reported. It is proposed that the cerebral structures involved in motor neglect are the same as those for sensory neglect and for the preparation of movement. As in sensory neglect, the multiplicity of the structures concerned suggests that this interconnection is necessary to maintain a sufficient level of activity. Predominance of left sided neglect by right sided lesions suggests that the left hemisphere is dominant for deliberate activity; hemispheric dominance could be applied to sensory neglect where conscious awareness would play the role of deliberate activity.

摘要

运动忽视的特征是一侧利用不足,而不存在力量、反射或感觉缺陷。本文报告了20例导致运动忽视但均无感觉忽视的额叶、顶叶和丘脑病变病例。有人提出,参与运动忽视的脑结构与参与感觉忽视和运动准备的脑结构相同。与感觉忽视一样,相关结构的多样性表明这种相互连接对于维持足够的活动水平是必要的。右侧病变导致左侧忽视占主导,这表明左半球在有意活动中占主导;半球优势可应用于感觉忽视,其中意识觉知将发挥有意活动的作用。
