灵长类顶叶下小叶皮质对空间知觉和空间定向行为具有重要作用。记录的单个神经元在这一领域的行为猴子表明，视觉敏感性的视网膜感受野的变化系统的注视角度。许多神经元的活动在很大程度上可以通过增益因子的乘积来描述，增益因子是眼睛位置和视觉感受野的响应曲线的函数。该操作产生针对以头部为中心的坐标空间中的位置的眼睛位置依赖性调谐。
The cortex of the inferior parietal lobule in primates is important for spatial perception and spatially oriented behavior. Recordings of single neurons in this area in behaving monkeys showed that the visual sensitivity of the retinotopic receptive fields changes systematically with the angle of gaze. The activity of many of the neurons can be largely described by the product of a gain factor that is a function of the eye position and the response profile of the visual receptive field. This operation produces an eye position-dependent tuning for locations in head-centered coordinate space.
