Highlights • It is commonly assumed that grid cell inputs generate hippocampal place fields, but recent empirical evidence brings this assumption into doubt.• We suggest that place fields are primarily determined by environmental sensory inputs.• Grid cells provide a complementary path integration input and large-scale spatial metric.• Place and grid cell representations interact to support accurate coding of large-scale space.

网格单元对位置单元发射有何贡献？

亮点 • 通常假设网格单元输入会产生海马位置场，但最近的经验证据对这一假设提出了质疑。• 我们建议位置场主要由环境感觉输入决定。• 网格单元提供互补的路径集成输入和大尺度空间度量。• 位置和网格单元表示交互以支持大规模空间的准确编码。
