有机体准确地从一个地方导航到另一个地方的能力需要整合多个空间结构，包括确定一个人在空间中相对于异中心地标的位置和方向、运动速度以及运动目标的感知位置。在这篇综述中，我们提出，虽然边缘区域对于空间方向感很重要，但后顶叶皮层负责将这种感觉与导航目标的位置联系起来，并制定实现该目标的计划。因此，后顶叶皮层对于计算导航时要遵循的正确轨迹或路线非常重要。前额叶和运动区随后负责执行计划的运动。利用这一理论，我们能够弥合啮齿类和灵长类文献之间的差距，表明啮齿类 PPC 的异中心作用在很大程度上类似于灵长类中通常强调的自我中心作用，即在目标导向运动的规划中将空间定向与潜在目标相结合。
The ability of an organism to accurately navigate from one place to another requires integration of multiple spatial constructs, including the determination of one's position and direction in space relative to allocentric landmarks, movement velocity, and the perceived location of the goal of the movement. In this review we propose that while limbic areas are important for the sense of spatial orientation, the posterior parietal cortex is responsible for relating this sense with the location of a navigational goal and in formulating a plan to attain it. Hence, the posterior parietal cortex is important for the computation of the correct trajectory or route to be followed while navigating. Prefrontal and motor areas are subsequently responsible for executing the planned movement. Using this theory, we are able to bridge the gap between the rodent and primate literatures by suggesting that the allocentric role of the rodent PPC is largely analogous to the egocentric role typically emphasized in primates, that is, the integration of spatial orientation with potential goals in the planning of goal-directed movements.
