Grid cells are neurons in the entorhinal cortex that are thought to perform computations in support of spatial navigation. As direct recordings of grid cells from the human brain are only rarely possible, functional magnetic resonance imaging (fMRI) studies proposed and described an indirect measure of entorhinal grid-cell activity, which is quantified as a hexadirectional modulation (HM) of fMRI activity as a function of the subject’s movement direction through a virtual environment. However, the contributing role of the aggregated activity of grid cells to this modulation remains unclear. Ou
