Geometry as a Guide: Enclosure Effects on Spatial Mapping (Commentary on Xu et al. 2024).

A recent paper by Xu et al. proposes that cognitive maps in mice emerge during spatial navigation from path integration anchored to a starting position. We challenge this understanding by arguing that enclosure geometry rather than path integration shapes cognitive maps.

The grid-cell normative model: Unifying 'principles'.

A normative model for the emergence of entorhinal grid cells in the brain's navigational system has been proposed (Sorscher et al., 2023. Neuron 111, 121-137).
