The activations and deactivations are thresholded at P < 0.00001, uncorrected. ∆>100% are shown in bold and colored in red (activations) or light blue (deactivations). ∆<−50% are shown in bold and colored in orange (activations) or green (deactivations). Abbreviations: ∆: (PSGS − NO PSGS)/NO PSGS∗100%.
