Abstract

Grid cells are neurons whose regularly spaced firing fields form apparently symmetric arrays, or grids, that are thought to collectively provide an environment-independent metric framework for the brain's cognitive map of space. However, two recent studies show that grids are naturally distorted, revealing greater local environment-specific effects than previously recognized.

摘要

网格细胞是一类神经元，其规则间隔的放电场形成明显对称的阵列，即网格，人们认为这些网格共同为大脑的空间认知地图提供了一个独立于环境的度量框架。然而，最近的两项研究表明，网格会自然扭曲，揭示出比之前认识到的更大的局部环境特异性效应。
