Stability of the homogeneous stationary solutions for heterogeneous perturbations.
(A) Spectrum of the full Jacobian matrix 
(blue dots, 
) compared with predictions from the random matrix approximation. The dashed black circle corresponds to the radius r (25), the orange and green markers indicate the predicted outliers 
and 
, respectively. In this panel J0 = 0.1 and 
. (B) Maximum real part of the eigenvalue spectrum of 
as a function of J0, compared with the radius r predicted by the random matrix approximation for various values of I0. (C) Critical coupling Jc as a function of network size N for different values of I0.
