DOI: 10.1016/j.cobeha.2017.08.012
Abstract: It has been proposed that path integration in mammals is performed by the convergence of internally generated speed and directional inputs onto grid cells. Although this hypothesis has been supported by the discovery that head… read more here.

DOI: 10.1016/j.cub.2017.06.067
Abstract: The firing fields of mammalian grid cells, which map an animal's environment, lie on hexagonal lattices. Three new studies report significant field-to-field differences in the firing rates, a finding with far-reaching consequences for how grid… read more here.

DOI: 10.1038/s41586-021-03783-x
Abstract: As animals navigate on a two-dimensional surface, neurons in the medial entorhinal cortex (MEC) known as grid cells are activated when the animal passes through multiple locations (firing fields) arranged in a hexagonal lattice that… read more here.

DOI: 10.1038/s41593-017-0036-6
Abstract: Natural environments are represented by local maps of grid cells and place cells that are stitched together. The manner by which transitions between map fragments are generated is unknown. We recorded grid cells while rats… read more here.

Abstract: Neuroimaging studies of human entorhinal cortex activity revealed 60-degree spatial periodicity, a hallmark of grid cells, as gaze movements were made throughout the visual field. This activity may serve as a framework for organizing visuospatial… read more here.

DOI: 10.1038/s41593-021-00907-4
Abstract: We investigated how entorhinal grid cells encode volumetric space. On a horizontal surface, grid cells usually produce multiple, spatially focal, approximately circular firing fields that are evenly sized and spaced to form a regular, close-packed,… read more here.
