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

从功能上讲，在视觉注视过程中，抑制眼球运动对于将目标的图像保持在中心凹(选择性注意)是必不可少的。在本研究中，我们在猴额叶视野(FEF)中确定了一个局部区域，在该区域，电刺激在低阈值下诱导抑制双侧眼跳的启动。这一区域还与刺激对平稳追踪眼动的抑制效应有关，提示眼跳和追踪的抑制控制可能是通过FEF中共同的神经元组装来实施的。

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.
