Fig. 7: Multi-scale fluctuations of spindle-band power.

Fig. 7

Grand average of the spectral profile at the scalp derivation C4, ranging from 0.001 to 0.12 Hz (a) and 0.1 to 0.6 Hz (b) frequency range of the sleep spindle frequency band (11–16 Hz) power fluctuation during NREM2 sleep episodes across the whole night. The peaks around 0.02 and 0.2 Hz for both the IMMO (purple) and CTRL (pink) groups highlight the multi-scale periodicity of spindle-band power at an infraslow and mesoscale rhythms, respectively. The lighter areas surrounding the mean represent the standard error of the means.
