B. RNAseq data are plotted in log2 fold change (FC) levels of protrusions over cell bodies against adjusted -log10 false discovery rate (FDR) (n=2 replicates, average FC values are represented). The horizontal dashed line marks the FDR (q) = 0.05 threshold; vertical dashed lines mark the FC = 0.625 (left) or FC = 1.6 (right) thresholds.
