This view is compatible with grid cells recorded in empty boxes but inconsistent with data from more naturalistic settings. We review evidence arguing against the global-metric notion, including <strong><span style=\"color: #ff0000;\">the distortion and disintegration of the grid pattern in complex and three-dimensional environments<\/span><\/strong>. We argue that deviations from lattice symmetry are key for understanding grid-cell function. <strong><span style=\"color: #ff0000;\">We propose three possible functions for grid cells<\/span><\/strong>, which treat real-world grid distortions as a feature rather than a bug. First, grid cells may <strong><span style=\"color: #ff0000;\">constitute a local metric<\/span> <\/strong>for proximal space rather than a global metric for all space. Second, grid cells could <strong><span style=\"color: #ff0000;\">form a metric for subjective action-relevant space<\/span><\/strong> rather than physical space. Third, <strong><span style=\"color: #ff0000;\">distortions may represent salient locations<\/span><\/strong>. Finally, we discuss mechanisms that can underlie these functions. These ideas may transform our thinking about grid cells.&#8221;<\/p>\n<p style=\"text-align: justify;\">Ginosar, Gily, Johnatan Aljadeff, Liora Las, Dori Derdikman, and Nachum Ulanovsky. &#8220;<a href=\"https:\/\/www.cell.com\/neuron\/fulltext\/S0896-6273(23)00223-4\"><strong>Are grid cells used for navigation?
