A Compressing Auto-encoder as a Developmental Model of Grid Cells

The metric representation of space during navigation is attributed to grid cells in the entorhinal cortex. The cell responses form triangular grid-like patterns that tile the entire environment as an animal moves (Giocomo, Moser, and Moser [2011]). Earlier findings suggest that the precision of place cells in the hippocampus (CA1 area) of a rodent’s brain is increased by the inter-connectivity from grid cells in the parahippocampal CA3 area (Moser, Moser, and Roudi [2014]). Figure 1, left, shows the grid cells organised into modules where the receptive fields of the cells in one module have the same spacing and orientation but the scale differs in others forming multiple spatially scaled modules that together precisely encode position over a large space.
