Figure 2.
Significant differences in brain response between the sessions recorded after 14 h and 1.5 h of wakefulness. a, PER35/5 significantly reduced response in the right posterior inferior frontal gyrus during ES compared with MS. Statistical results are overlaid to the population mean structural image (p uncorrected < 0.001). No significant changes were observed in PER34/4. b, Mean activity estimates (a.u. ± SEM; in all figures * indicates the significant differences at p < 0.05 at the voxel level after correction for multiple comparisons).
