The grid cells that Nelson and NASA use to ... This is just one example of how Nelson’s map challenges our ideas of what density looks like. “Even among cells with similar population and ...

The metric of this representation is provided by grid cells, cells with spatial firing ... The discrete topography of the grid-map, and the apparent autonomy of the modules, differ from the ...

EC layers were classified using current-source density estimates (see Supplementary Methods). Grid cells were found at an approximately equal frequency across both superficial and deep layers (14 ...
