Abstract

We tested the hypothesis that the right hemisphere is dominant for motor activation of "intention." If the right hemisphere is dominant for intention and if intention is a prerequisite for movement, motor impairment should be worse after an infarct in the right hemisphere than in the left. We asked nine subjects with right and nine with left hemisphere infarcts to elevate each shoulder independently. Subjects with right hemisphere lesions had more trouble moving the contralateral shoulder. The data are consistent with the hypothesis that the right hemisphere is dominant for motor activation or intention.

摘要

我们检验了这样一个假设，即右半球在“意图”的运动激活方面占主导地位。如果右半球在意图方面占主导地位，并且如果意图是运动的先决条件，那么右半球梗死之后的运动障碍应该比左半球梗死之后更严重。我们让9名右半球梗死患者和9名左半球梗死患者分别独立抬起每一侧肩膀。右半球病变的患者在移动对侧肩膀时遇到更多困难。这些数据与右半球在运动激活或意图方面占主导地位的假设相一致。
