Grid cell symmetry is shaped by environmental geometry
Krupic et al. Nature
Grid-cell firing patterns were distorted by environmental geometry, showing that spatial coding is shaped by enclosure boundaries rather than being perfectly metric.
ND-0063 · 2020 · Human VR experiment
Deforming the metric of cognitive maps distorts memory
Authors per journal record. Nature Human Behaviour
Spatial memory and distance judgments were systematically distorted in deformed geometry, consistent with geometry-dependent cognitive maps.
ND-0065 · 2010 · Human neuroimaging study
Evidence for grid cells in a human memory network
Doeller, Barry & Burgess. Nature
Human entorhinal signals showed six-fold directional modulation consistent with grid-cell-like coding.
ND-0066 · 2006 · Foundational theory/review
The boundary vector cell model of place cell firing and spatial memory
Barry et al. Reviews in the Neurosciences
Proposes that boundaries at specific distances and directions contribute to place-cell firing and spatial memory.
ND-0112 · 2022 · Review
A theory of geometry representations for spatial navigation
Authors per journal record. Progress in Neurobiology
Synthesizes how the brain may represent environmental geometry for navigation across several coding systems.
ND-0114 · 2026 · Review
(Remembering) Vector Coding of Boundaries and Objects in the Subiculum
Colin Lever. Hippocampus
Reviews vector coding of environmental boundaries and objects in hippocampal-related systems.
