By means of their efferent projections to motor and premotor structures, the cells in the deep superior colliculus are intimately involved in behaviors that control the orientation of the eyes, pinnae, and head. These same efferent cells receive multiple sensory inputs, thereby apparently enabling an animal to orient its receptor organs in response to a wide variety of cues. This sensory convergence also provides a system in which motor responses need not be immutably linked to individual stimuli but can vary in reaction to the multitude of stimuli present in the environment at any given moment.
通过其向运动和运动前结构的传出投射，上丘深部的细胞密切参与控制眼睛、耳廓和头部定向的行为。这些相同的传出细胞接收多种感觉输入，从而显然使动物能够根据各种各样的线索定向其感受器器官。这种感觉汇聚还提供了一个系统，在这个系统中，运动反应不必一成不变地与单个刺激相关联，而是可以根据任何给定时刻环境中存在的大量刺激而变化。
