We explored spatio-temporal gene expression as well as rs-fMRI connectivity patterns in preterm newborns. We observe an important role of the somatosensory and motor cortices that might be linked to specific gene expressions in the same regions.
Figure 3: (A) Positive delta (neonatal vs late fetal) changes. Nodal size corresponds to the delta values: bigger nodes corresponds to higher functional maturation values. (B) Negative delta changes: bigger nodes correspond to lower functional maturation values. (C) Bar plot showing both positive and negative delta values for the 11 regions. The brain plots were created by mapping the delta values of these 11 regions to the corresponding AAL regions. Nodes with same colour belong to the same region (of these 11). The abbreviations correspond to the standard AAL 90 regions atlas.
