P _corr stands for nonstationary, whole brain corrected cluster P‐values, k for the cluster size, t _peak for the t‐value of the peak‐voxel (F for F‐value), Inf for inferior, Sup for superior, [x, y, and z] coordinates are in MNI‐space. Post‐hoc contrasts were computed with sleep restriction, S2 amount and S4 amount as covariates. There were no significant clusters of activation at the employed threshold in other post‐hoc contrasts. The cluster in the amygdala and hippocampus was noted also for the CS_E (left, P _corr = 0.156, and right, P _corr = 0.166) and for the CS_U (left, P _corr = 0.174).
