Fig. 3

Topographical statistical map of the difference in SO (0.5–1.25 Hz) spectral power between the IMMO and CTRL groups during the first 20 min of NREM2 sleep (IMMO-CTRL contrast). The color bar represents the t-test values. Negative t values (blue) represent lower spectral power for the IMMO group (n = 15) compared with the CTRL group (n = 15). White areas represent the non-significant differences between groups after the Student’s t permutation test (1000 permutations). The red dots highlight the electrodes with statistical differences after correction for multiple comparisons using the Benjamini–Hochberg procedure to control the false discovery rate (Ntests = 63).
