Six right-handed patients with a lesion affecting the left (3 patients) or right (3 patients) supplementary motor area were studied using single and sequential memory-guided saccade paradigms. Accuracy of single saccades was preserved in both groups, compared to control subjects, and the chronology of saccade sequences was disturbed in the group with the left lesion but not in the group with the right lesion. The results suggest that neither side of the supplementary motor area is involved in spatial memory, and that the left supplementary motor area plays a greater role in motor sequencing than does the right supplementary motor area.
对六名右利手患者进行了研究，这些患者的病变影响了左（3例）或右（3例）辅助运动区，采用了单次和连续记忆引导扫视范式。与对照组相比，两组患者单次扫视的准确性均得以保留，且左病变组扫视序列的时间顺序受到干扰，而右病变组则未受影响。结果表明，辅助运动区的任何一侧均不参与空间记忆，且左辅助运动区在运动序列方面比右辅助运动区发挥着更大的作用。
