The role of oscillations in grid cells’ toroidal topology

Fig 8

The dependence of the degree of toroidality on the field size with and without oscillations.

(A, B) The barcodes of the simulated populations modulated by oscillations are similar to the associated experimental module for large enough values of , averaged over 20 realizations (shaded area indicates standard deviation). The parameters for the oscillations are as described in Methods. Removing the oscillations dramatically reduces this similarity and increases the variability both in (A) and (B). (C, D) Similarity measures and between the barcodes from the simulations and a reference barcode produced from the simulated population with two long bars in H₁ and one long bar in H₂, as descried in text.
