Fig. 8.

(A) Experimental data of grid cell firing patterns deformed, curving away from a wall in an irregular geometry. (B1) A full simulation of Eq. 15. Eq. 13 also yields grid firing patterns bent away from the wall. (B2) Visualization of the average attractor state as a function of position ${\mathit{\varphi }}^{\mathbf{\text{A}}}\left(\mathbf{\text{r}}\right)$ (periodicity removed for visualization purposes). The reversal between the bending of the internal attractor phase and the bending of firing-rate maps is similar to the reversal seen in Fig. 6B. (C1 and C2) Same as B1 and B2, but for a slightly different geometry.
