先前的功能性磁共振成像研究结果表明，运动前区-顶叶网络参与了序列信息的知觉加工。鉴于运动前区功能传统上仅限于需要运动或感觉运动计算的行为，本患者研究的目标是进一步研究外侧运动前区皮质在纯粹的感知排序中是否至关重要。腹侧运动前区或下顶叶病变的患者，除了患者与前额叶病变和年龄和性别匹配的健康对照，进行了测试，在处理的时间，对象特异性，和空间序列。结果显示，运动前患者以及顶叶患者在所有序列任务中的错误率均显著高于健康对照组。相比之下，前额叶患者没有表现出行为缺陷。这些发现支持腹外侧运动前区皮质的重要性，除了顶叶区，在非运动（注意）功能。
Previous functional MRI findings have indicated that a premotor-parietal network is involved in the perceptual processing of sequential information. Given that premotor functions have traditionally been restricted to behaviors requiring motor or sensorimotor computations, the goal of the present patient study was to further investigate whether the lateral premotor cortex is critical in purely perceptual sequencing. Patients with either ventral premotor or inferior parietal lesions, in addition to patients with prefrontal lesions and age- and gender-matched healthy controls, were tested during the processing of temporal, object-specific, and spatial sequences. Results revealed that premotor patients as well as parietal patients showed significantly higher error rates than did healthy controls on all sequence tasks. In contrast, prefrontal patients showed no behavioral deficits. These findings support the significance of the ventrolateral premotor cortex, in addition to parietal areas, in nonmotor (attentional) functions.
