Figure 2. Global properties of the functional connectivity.

A) Reshaping the connectivity matrices as high-dimensional vectors. B) Projection of the vectorized connectivity matrices onto the first three principal components. The matrices of control and ASD are clearly separable. C) Linear stability analysis of the connectivity matrices reveals no significant differences between control and ASD. The y-axis plot the largest real part of the eigenvalues of each matrix. D) There are no significant differences in the correlation between nodal input and nodal output (I: input; O: ouput; +: excitatory; −: inhibitory).
