oligodendrocytes, astrocytes and neurons, respectively, in every network (P ≤ 4.3 × 10−37, P ≤ 2.5 × 10−61 and P ≤ 5.4 × 10−5, respectively; Table 1 and Supplementary Table 7 online). Comparisons with the results of genome-wide in situ hybridization experiments from the Allen Brain Atlas31 revealed that M9, M15 and M16 were significantly enriched with markers of oligodendrocytes, astrocytes and neurons, respectively, in every network (P ≤ 1.1 × 10−27, P ≤ 7.2 × 10−9 and P ≤ 0.041, respectively; Table 1 and Supplementary Table 7).
