Maps of cells in clusters with enhanced synchronisation and cluster order parameter $R_c$ for each cluster of the cell population of density $\rho =0.1\%$ (shown in Fig. 1). (a, c) Maps of clusters with enhanced synchrony during partial synchronisation. When the cluster order parameter exceed the threshold of $R_c\ge 0.75$, the phases ${\varphi }_i$ of the cells were mapped onto their positions, else the cells are indicated by points. Clusters obtained by segmentation with respect (a) to $r_{\mathit{ij}}$ and (c) to ${\sigma }_i$. Video S2 compiles the time evolution of the dynamics in the spatial clusters. Persistence of the enhanced synchrony in the clusters obtained by segmentation (b) with respect to $r_{\mathit{ij}}$ and (d) to ${\sigma }_i$.
