This article reviews some recent findings on the character of the neuronal organization lying between the optic tectum and motor pattern-generating circuitry in the case of orienting behaviors. It focuses on frogs but notes parallels to existing work on saccade control in mammals and suggests some additional ones for further exploration. In general, the map-like function of orienting does not appear to be subserved by a comparable map-like organization. It is argued that the current conceptual vocabulary for describing interface organization (sensory map, motor map, pattern-generating circuitry) is inadequate and that some additional concepts (activity-gated divergence, intermediate spatial representation) are necessary. Finally, some questions are raised about the appropriateness of the term 'motor map'.
本文回顾了一些关于在定向行为中位于视顶盖和运动模式生成回路之间的神经元组织特征的近期研究发现。它主要聚焦于青蛙，但也指出了与哺乳动物扫视控制方面现有研究的相似之处，并提出了一些有待进一步探索的其他相似点。总体而言，定向的地图样功能似乎并非由类似的地图样组织所支持。有人认为，当前用于描述界面组织（感觉地图、运动地图、模式生成回路）的概念词汇并不充分，还需要一些额外的概念（活动门控发散、中间空间表征）。最后，针对“运动地图”这一术语的适用性提出了一些问题。
