Single unit responses were recorded in the pulvinar nucleus of the squirrel monkey (Saimiri sciureus) while awake and alert, with the head fixed but free to make eye movements. Peri-saccadic time histograms revealed only post-saccadic responses to eye movements made spontaneously in the dark or in a uniformly illuminated field (Ganzfeld), or to trained eye movements made in response to a spot of light in the periphery. Of 120 pulvinar neurons that responded to eye movements in the light, approximately one-quarter was responsive to eye movements in the dark. In one group of monkeys about half of the eye movement-responsive cells in the light were responsive to light flash in the dark; in another group approximately half of the eye movement-responsive cells in the light were also responsive to trained eye movements. Of particular interest is the fact that pulvinar neurons responsive to eye movements were located within a restricted region oriented vertically and cutting across lateral and inferior pulvinar, rostrally, and lateral and medial pulvinar, caudally. The results have been interpreted as supporting the concept of convergence and integration of visual and oculomotor input in the pulvinar and also its potential role in the mediation of visual attention.
在清醒警觉的松鼠猴（Saimiri sciureus）的丘脑枕核中记录单个神经元的反应，实验时头部固定，但可自由进行眼球运动。扫视周围时间直方图显示，仅在黑暗中或均匀照明场（全视野）中自发进行的眼球运动，或对周边光点做出的训练性眼球运动后，才会出现扫视后反应。在120个对光下眼球运动有反应的丘脑枕神经元中，约四分之一对黑暗中的眼球运动有反应。在一组猴子中，光下约一半对眼球运动有反应的细胞对黑暗中的闪光有反应；在另一组中，光下约一半对眼球运动有反应的细胞也对训练性眼球运动有反应。特别值得关注的是，对眼球运动有反应的丘脑枕神经元位于一个垂直定向的受限区域内，该区域从前向后穿过丘脑枕外侧和下部，以及从尾向头穿过丘脑枕外侧和内侧。这些结果被解释为支持丘脑枕中视觉和动眼神经输入的汇聚与整合概念，以及其在视觉注意力调节中的潜在作用。
