Figure 4.
Neural activity related to the onset of the decision option (conjunction analysis control + sleep-deprived, pFWE < 0.05 corrected for whole-brain volume) projected onto a glass brain (a). The most prominently activated clusters were located in the lateral occipital cortex (LOC), ACC, and inferior frontal gyrus (IFG) (b). In these regions, task-related responses were of similar magnitude in CON and SD. c, Right insula activation was greater in CON than SD, whereas a posterior mOFC cluster showed greater activity for SD than CON. Activations are projected onto the mean normalized T1 image.
