Neural basis for the control of visual fixation and eye movements by the frontal eye field and the superior colliculus

在功能上，眼球运动的抑制在视觉固定过程中是必要的，以保持目标的图像在中央凹（选择性注意）。在本研究中，我们确定了猴子额眼野（FEF）的一个局部区域，在该区域，电刺激在低阈值下诱导抑制了双侧扫视的开始。该区域还与刺激对眼球平滑追求运动的抑制作用有关，这表明对扫视和追求的抑制控制可能是由FEF中一个共同的神经元集合施加的。

Functionally, the suppression of eye movements is essential during visual fixation to hold the image of the target on the fovea(selective attention). In the present study, we identified a localized area in the monkey frontal eye field(FEF) at which electrical stimulation induced suppression of the initiation of saccades bilaterally at low thresholds. This area was also associated with the suppressive effect of stimulation on smooth pursuit eye movements, suggesting that the suppressive control of saccades and pursuit may be exerted by a common neuronal assembly in the FEF.
