神经生理学研究表明，大鼠位置和头部方向(HD)细胞的放电可以与可感知环境的特征联系在一起，这表明这些特征部分地指定了大鼠的位置和方向。相比之下，行为学研究表明，迷失方向的大鼠和人类儿童完全依赖于他们周围环境的形状，而忽略了许多地方和HD细胞对其做出反应的信息。在目前的研究中，通过调查幼儿在迷失方向后在正方形房间中定位物体的能力来探索这种差异。18-24个月大的孩子使用独特的几何提示来定位物体，而不是使用独特的彩色墙壁，即使他们熟悉了彩色墙壁。结果表明，重新定向和物体定位背后的空间表征在人类和其他哺乳动物中是共同的。结合神经生理学的发现，这些实验对海马区和HD细胞作为目标定位的一般定位装置的假设提出了质疑。
Neurophysiological studies show that the firing of place and head-direction (HD) cells in rats can become anchored to features of the perceptible environment, suggesting that those features partially specify the rat's position and heading. In contrast, behavioral studies suggest that disoriented rats and human children rely exclusively on the shape of their surroundings, ignoring much of the information to which place and HD cells respond. This difference is explored in the current study by investigating young children's ability to locate objects in a square chamber after disorientation. Children 18–24 months old used a distinctive geometric cue but not a distinctively colored wall to locate the object, even after they were familiarized with the colored wall. Results suggest that the spatial representations underlying reorientation and object localization are common to humans and other mammals. Together with the neurophysiological findings, these experiments raise questions for the hypothesis that hippocampal place and HD cells serve as a general orientation device for target localization.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
