Numerical analysis of the EN dynamics with uniform orientation stimulus ensemble and fixed representation of visual space far from pattern formation threshold. (a) OPMs and their power spectra in a representative simulation of Equation (3) with r(x) = 0, r = 0.8, σ/Λ = 0.3 (η = 0.028) and uniform stimulus ensemble. (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 and their power spectra in a representative simulation of Equation (3) with r(x) = 0 and σ/Λ = 0.12 (η = 0.57), other parameters as in a. (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).
