Attention influences the processing of visual information even in the earliest areas of primate visual cortex. There is converging evidence that the interaction of bottom-up sensory information and top-down attentional influences creates an integrated saliency map, that is, a topographic representation of relative stimulus strength and behavioral relevance across visual space. This map appears to be distributed across areas of the visual cortex, and is closely linked to the oculomotor system that controls eye movements and orients the gaze to locations in the visual scene characterized by a high salience.
注意力甚至在灵长类动物视觉皮层的最早期区域就会影响视觉信息的处理。越来越多的证据表明，自下而上的感觉信息与自上而下的注意力影响之间的相互作用会产生一个整合的显著性图，即视觉空间中相对刺激强度和行为相关性的地形图。这个图似乎分布在视觉皮层的各个区域，并且与控制眼球运动并将目光导向视觉场景中具有高显著性位置的动眼系统紧密相连。
