Extended Data Fig. 1: Naive addition of gradient in CAN does not form modularity.
From: Global modules robustly emerge from local interactions and smooth gradients

(a-c) Naive merger of the two mechanisms by smoothly scaling the width of the pattern-forming lateral interaction in the grid cell CAN model18 does not generate global modularity in 2-dimensional (b) or 1-dimensional (c) grid models: the result is one smoothly varying periodic pattern.
