Abstract

Neuronal grid cells fire in a spatial grid pattern laid out across the surface of a familiar environment, however the role of environmental boundaries in the construction of this pattern is not well understood; this study shows that the grid pattern orients to the walls of polarized environments such as squares but not circles and that the hexagonal grid symmetry is permanently broken in highly polarized environments such as trapezoids.
