A virtual rat randomly explored a virtual burrow, based on those observed by John B. Calhoun, with chambers and tunnels.","gist":"Simulating a virtual rat exploring a burrow-like environment, the authors found that grid cell patterns lose long-range order and become incoherent clusters, unlike in a flat box.","meaning":"Most grid cell research uses simple, flat, open enclosures, but animals in the wild move through irregular spaces. The claim says that, in the model, the burrow's shape largely undermines the regular hexagonal firing patterns seen in lab boxes. Connections between grid units help only modestly and only if they are of the right strength. If it holds, it suggests grid cells in natural settings may behave quite differently from the classic picture.","findings":["Lateral connections between grid units may improve gridness, but only within a limited range of strength.","The irregular burrow geometry disables long-range order and obstructs short-range order in the grid patterns.","What looks like a smooth continuous attractor in a flat box becomes an incoherent mix of unit clusters, flexible or unstable."],"terms":[{"term":"gridness","means":"A score of how closely a cell's firing pattern forms a regular, repeating hexagonal grid across space."},{"term":"lateral connectivity","means":"Connections between units of the same kind, here between grid units, as opposed to input arriving from another cell type."},{"term":"long-range and short-range order","means":"How far the regular repeating pattern of grid firing stays consistent across space, over large distances or only nearby."}],"basis":"abstract","abstractFrom":"crossref","model":"claude-sonnet-5-5","writtenAt":"2026-10-15T20:46:58.883Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-15T20:46:58.883Z","attempts":1,"model":"claude-sonnet-5-5","why":null},"note":"Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong.
