Table 2.
Mean and standard deviation of spectral power in different frequency bands. Values were calculated over the entire night (normal font) and over the first 2 hours after lights out (in italics).

Experimental conditions: Baseline (B), vestibular stimulation until sleep onset (C1), vestibular stimulation for 2 hours after lights out (C2). Delta band: 0.75–4.5 Hz; Theta band: 4.5–9 Hz; Alpha band: 9–15 Hz; Sigma band: 11–15 Hz; Beta band: 15–25 Hz. No significant differences were observed.
