一个新的或行为上重要的刺激的突然发作通常会触发将眼睛、外耳、头部和/或身体定向到刺激源的反应。因此，便于接收源自源的附加信号以及适当的肢体和身体运动的感觉引导。来自解剖学、电生理学和损伤实验的证据表明，上级丘是负责产生定向反应的神经基质的重要组成部分。本文简要回顾了哺乳动物上级丘的功能组织，并讨论了可能的联系之间的感觉和运动地图观察到在这个结构。假设是先进的感觉地图组织在电机（而不是感觉）坐标和感觉空间的地图是动态的，转移与眼睛，头部和身体的相对运动。
The sudden onset of a novel or behaviorally significant stimulus usually triggers responses that orient the eyes, external ears, head and/or body toward the source of the stimulus. As a consequence, the reception of additional signals originating from the source and the sensory guidance of appropriate limb and body movements are facilitated. Converging lines of evidence, derived from anatomical, electrophysiological and lesion experiments, indicate that the superior colliculus is an important part of the neural substrate responsible for the generation of orienting responses. This paper briefly reviews the functional organization of the mammalian superior colliculus and discusses possible linkages between the sensory and motor maps observed in this structure. The hypothesis is advanced that the sensory maps are organized in motor (not sensory) coordinates and that the maps of sensory space are dynamic, shifting with relative movements of the eyes, head and body.
