The linearization of the EN model dynamics around the unselective fixed point. (a) Eigenvalue spectra of the linearized retinotopy dynamics for longitudinal mode ( λ L r ( k ) , blue trace) and transversal mode ( λ T r ( k ) , red trace). (b) Longitudinal mode ~ k ϕ e i k ϕ x +c.c. (left) and transversal mode ~ k ϕ + π 2 e i k ϕ x +c.c. (right). (c) Spectrum of eigenvalues of the linearized OPM dynamics (red trace) for σ < σ*(η). Orange region marks the unstable annulus of Fourier modes (critical circle). (d) Stability regions of the nonselective state in the EN model. The stability border is given by σ*(η) (Equation (12)).
