Two or three sites in the region of the frontal lobe of marmoset and squirrel monkey are definable as frontal eye fields (FEF) on the basis of electrical stimulation which results in slow and/or saccadic eye movements. In the squirrel monkey these are located on the banks of the arcuate and principal sulci; in the marmoset at estimated analogous locations. Eye ball deviations result from stimulation of these sites with a return to initial position at the end of stimulation. The induced eye movements included large, slow eye movements of varying speeds, micro- and macro-saccades, pendular eye movements, and saccadic stairways. The direction of these eye movements depended on the site stimulated. Both smooth slow and saccadic eye movements were obtained even with stimulation of the same site, depending on the stimulus intensity and the depth of anesthesia. A precise relationship between the site stimulated and the type of eye movement elicited could not be established in these species. Effective stimulus was 300 Hz frequency, 0.2-0.5 ms pulse duration, 0,05-0.05 mA current, and trains of 4-160 pulses. Characteristically, sites for induction of saccadic eye movements were frontal to sites for induction of slow eye movements.
根据电刺激能引发缓慢和/或扫视性眼球运动这一现象，在狨猴和松鼠猴的额叶区域可确定两到三个部位为额叶眼区（FEF）。在松鼠猴中，这些部位位于弓形沟和中央沟的脑岸上；在狨猴中则位于估计的类似位置。刺激这些部位会导致眼球偏斜，刺激结束时眼球会回到初始位置。诱发的眼球运动包括不同速度的大幅度缓慢眼球运动、微扫视和宏扫视、钟摆式眼球运动以及扫视阶梯。这些眼球运动的方向取决于所刺激的部位。即使刺激同一部位，根据刺激强度和麻醉深度，也能获得平稳缓慢和扫视性两种眼球运动。在这些物种中，无法确定所刺激部位与诱发的眼球运动类型之间的确切关系。有效刺激参数为300赫兹频率、0.2 - 0.5毫秒脉冲持续时间、0.05 - 0.5毫安电流以及4 - 160个脉冲的序列。典型的情况是，诱发扫视性眼球运动的部位在诱发缓慢眼球运动的部位前方。
