In this chapter, we consider the contribution of the posterior parietal cortex (PPC) to obstacle avoidance behavior and we define a model that identifies the major planning processes that are required for this task. A key aspect of this planning process is the need to integrate information concerning the obstacle, obtained from vision, together with an estimation of body and limb state. We suggest that the PPC makes a major contribution to this process during visually guided locomotion. We present evidence from lesion and single unit recording experiments in the cat that are compatible with this viewpoint.
在本章中，我们将探讨后顶叶皮层 (PPC) 在障碍物回避行为中的作用，并定义一个模型，该模型确定了完成这项任务所需的主要规划过程。这个规划过程的一个关键方面是需要将来自视觉的有关障碍物的信息与对身体和肢体状态的估计结合起来。我们认为，在视觉引导的运动中，PPC 对这个过程做出了重大贡献。我们提出了来自猫的损伤和单细胞记录实验的证据，这些证据与这一观点相符。
