Order parameter as a function of the synaptic gain $\left(g\right)$ of connections and frequency bands $\left(\delta ,\alpha \hspace{0.17em},\beta ,\hspace{0.17em}\gamma \right)$ for increasing the myelination rate $\left(\mathit{ϵ}\right)$. In each case, the order parameter $r$ was measured across independent trials, for increasing synaptic gain $g$ and local oscillation frequency. As the myelination rate is increased from $\mathit{ϵ}=0$ to $\mathit{ϵ}=0.2$ (i.e., from the not plastic to the plastic case), the phase-locking region increases. In the absence of adaptive myelination, phase locking is achieved only for strong coupling and for low frequencies. When $\mathit{ϵ}$ is increased, the synchronization regime becomes more prevalent, not only for higher coupling gains but also across frequency bands and for weaker synaptic coupling: (A) $\mathit{ϵ}=0.0$, (B) $\mathit{ϵ}=0.1$, and (C) $\mathit{ϵ}=0.2$. Here, ${\alpha }_c=1$.
