注意力可以在没有眼球运动的情况下被“隐蔽地”引导;然而，即使在注视期间，也存在连续的微扫视（MS）。在猕猴的V4区和IT区，我们发现，放电率和刺激表征增强注意，但只有以下MS对出席的刺激。神经注意力调节的发生与MS的发生密切相关。结果揭示了内隐注意对皮层视觉处理的影响与眼睛的外显运动之间的主要联系。注意力可以在没有眼球运动的情况下被“隐蔽地”引导;然而，即使在注视期间，也存在微扫视。我们发现，神经活动被注意力增强，但只有在对刺激进行微扫视之后，才能揭示内隐注意力和眼神经系统之间的主要联系。
Attention can be “covertly” directed without eye movements; yet, even during fixation, there are continuous microsaccades (MSs). In areas V4 and IT of macaques, we found that firing rates and stimulus representations were enhanced by attention but only following a MS toward the attended stimulus. The onset of neural attentional modulations was tightly coupled to the MS onset. The results reveal a major link between the effects of covert attention on cortical visual processing and the overt movement of the eyes. Attention can be “covertly” directed without eye movements; yet, even during fixation, there are microsaccades. We found that neural activity was enhanced by attention, but only following a microsaccade toward the stimulus, revealing a major link between covert attention and the oculomotor system.
