Abstract Recent work has claimed that the emergence of grid cells from trained path-integrator circuits is a more fragile phenomenon than previously reported. In this note we critically assess main analysis and simulation results underlying claim, within proper context published theoretical work. Our assessment reveals entirely consistent with prior theory: hexagonal robustly emerge precisely when theory predicts they should, don’t should not.
