Grid cell symmetry is shaped by environmental geometry

What the study found

Grid-cell firing patterns were distorted by environmental geometry, showing that spatial coding is shaped by enclosure boundaries rather than being perfectly metric.

Limitations

Rodent neural data; direct human architectural translation is unproven.

Neurodesign interpretation

Geometry can enter the navigation system before conscious wayfinding judgment. The design question is whether certain forms systematically increase spatial uncertainty in humans.

Possible design implications

Use as a mechanism hypothesis for testing human navigation in irregular or polarized geometries, not as a direct design prescription.

Why it stays in the corpus

Retain as the canonical geometry-grid-cell mechanism source.
