Krupic, Bauza, Burton, Barry, & O'Keefe (Grid cell symmetry is shaped by environmental geometry. Nature, 518, 232-235, 2015) found that the grids of grid cells in the entorhinal cortex of rats become sparser at the sharp end of a trapezoidal space. This makes grids, and grid cells, unsuitable for measuring distance traveled (odometry) and suggests that grid cells may have more to do with sorting out directions.
克鲁皮克、包扎、伯顿、巴里和奥基夫（《网格细胞对称性受环境几何形状影响。自然》，2015年，第518卷，第232 - 235页）发现，在梯形空间的尖锐末端，大鼠内嗅皮质中网格细胞的网格会变得更稀疏。这使得网格以及网格细胞不适用于测量行进距离（里程计），并表明网格细胞可能更多地与分辨方向有关。
