Saccadic eye movements are controlled by a cortical network composed of several oculomotor areas that are now accurately localized. Clinical and experimental studies have enabled us to understand their specific roles better. These areas are: (1) the parietal eye field (PEF) located in the intraparietal sulcus involved in visuospatial integration and in reflexive saccade triggering; (2) the frontal eye field (FEF), located in the precentral gyrus, involved in the preparation and the triggering of purposive saccades; and (3) the supplementary eye field (SEF) on the medial wall of the frontal lobe, probably involved in the temporal control of sequences of visually guided saccades and in eye-hand coordination. A putative cingulate eye field (CEF), located in the anterior cingulate cortex, would be involved in motivational modulation of voluntary saccades. Besides these motor areas, the dorsolateral prefrontal cortex (dlPFC) in the midfrontal gyrus is involved in reflexive saccade inhibition and visual short-term memory.
扫视眼动由一个由几个现已精确定位的动眼区域组成的皮质网络控制。临床和实验研究使我们能够更好地理解它们的特定作用。这些区域包括：（1）位于顶内沟的顶叶眼区（PEF），参与视觉空间整合和反射性扫视触发；（2）位于中央前回的额叶眼区（FEF），参与目的性扫视的准备和触发；以及（3）位于额叶内侧壁的辅助眼区（SEF），可能参与视觉引导扫视序列的时间控制和眼手协调。位于前扣带回皮质的假定扣带回眼区（CEF），将参与自主扫视的动机调节。除了这些运动区域外，额中回的背外侧前额叶皮质（dlPFC）参与反射性扫视抑制和视觉短期记忆。
