Figure 5

Synchronization vs. identifiability. In (A), we show the correlation between the structural and functional networks \(Co(\mathbf{A}^{\xi },\mathbf{S})\) (blue line, values on the left vertical axis) and the optimal differential identifiability \(I_{diff}^{PCA}\) (orange line, values on the right vertical axis) as a function of the noise amplitude \(\xi\) for a fixed coupling parameter \(\kappa =0.075\). In the inset (A), we plot the differences between the normalized values \(I_{norm}-Co_{norm}\). Dashed lines indicate the values of \(\xi\) at where \(Co(\mathbf{A}^{\xi },\mathbf{S})\) and \(I_{diff}^{PCA}\) begin to decrease significantly. In (B), we plot the same variables as a function of the coupling strength \(\kappa\). In this case, we set the noise amplitude to \(\xi =0.18\).
