Raster plots (left) and normalized BOLD signals (right) for level \(\ell ^*_{13}\), for different values of noise standard deviation \(\sigma _A\) and for fixed \(\sigma =10^{-3}\) (see yellow dots in Fig. 8). Points in the raster plots denote the peaks of excitatory subpopulation activity of each node, with nodes belonging to the same cluster represented as adjacent to each other. The normalized BOLD signals correspond to nodes in three sample clusters, chosen to showcase clusters of different sizes (pink: 8 nodes, teal: 5 nodes, orange: 2 nodes). Values of \(\sigma _A\) increase from top to bottom and correspond to decreasing values of \(\bar{B}\).
