FIG. 7.

Phase diagram with the human brain network coupling strength distribution as a function of $\alpha$, $\beta$, and $d_0$ determining the form of the coupling function. Representative fixed values of $\alpha$ are chosen at (a) $\alpha =0$ where $\sin \alpha =0,\cos \alpha =1$, (b) $\alpha =0.25\pi$ where $\sin \alpha >0,\cos \alpha >0$, (c) $\alpha =0.5\pi$ where $\sin \alpha =1,\cos \alpha =0$, and (d) $\alpha =0.75\pi$ where $\sin \alpha <0,\cos \alpha >0$. Phase diagrams with order parameter $\tilde{R}$ (first row), phase spread $\mathrm{\Delta }=\omega -\mathrm{\Omega }$ (second row), and the slope of the amplitude curve $(K_j,{r_j}^{\ast })$ calculated as the average value of $\frac{\mathrm{\partial }{r}_j^{\ast }}{\mathrm{\partial }{K}_j}$ among the locked oscillators (third row). The boundaries and other details are as in Fig. 3. For the obtained coupling strength set $K_j$ with $N=989$, $(K_{\text{mean}},{\sigma }_K,K_{\text{min}},K_{\text{max}})=(36.5,15.8,1.01,98.1)\times {10}^{-3}$. Simulation parameters: $\lambda =1$, $\omega =\pi$, $S=1$, $N=989$.
