Approaching crystalline n -ECP optima in the EN model with fixed retinotopy. (a) OPMs (upper row) and their power spectra (lower row) in a simulation of Equation (3) with r(x) = 0, r = 0.1, σ/Λ = 0.2 and s4 = 6 (see also Additional file 3). The predicted optimum is the 2-ECP (black frame). (b) Pinwheel density time courses for four different simulations (parameters as in a; gray traces, individual realizations; black trace, simulation in a; red trace, mean value). (c) OPMs (upper row) and their power spectra (lower row) in a simulation of Equation (3) with r(x) = 0, r = 0.1, σ/Λ = 0.3 and s4 = 8 (see also Additional file 4). The predicted optimum is the anisotropic 3-ECP (black frame). (d) Pinwheel density time courses for four different simulations (parameters as in c; gray traces, individual realizations; black trace, simulation in c; red trace, mean value).
