Different paradigms of saccades were recorded electro-oculographically in 2 patients with infarction affecting the left supplementary motor area. Saccades made toward visual targets (visually-guided saccades) or away from them (antisaccades) were normal in both patients. Memory-guided saccades, made to the remembered position of a flash occurring 2 seconds before, were preserved in 1 patient and only slightly impaired in the other. However, sequences of two or three memory-guided saccades were severely impaired in both patients. It has previously been reported that the supplementary motor area plays an important role in programming sequential limb movements. Our data suggest that this area plays a similar role in the control of sequential eye movements.
采用眼电图记录了2例左侧辅助运动区梗死患者不同模式的扫视运动。两名患者向视觉目标进行的扫视运动（视觉引导性扫视）或背离目标的扫视运动（反扫视）均正常。对2秒前出现闪光的记忆位置进行的记忆引导性扫视，在1例患者中得以保留，在另一例患者中仅有轻微受损。然而，两名患者进行的连续两个或三个记忆引导性扫视序列均严重受损。此前有报道称，辅助运动区在编排肢体连续运动中起重要作用。我们的数据表明，该区域在控制眼球连续运动中起类似作用。
