Table 1 Absolute and relative alpha power densities in the occipital region

From: Rapid changes in arousal states of healthy volunteers during robot-assisted gait training: a quantitative time-series electroencephalography study

Absolute power density (mean ± SE, μV2) Relative power densitya(mean ± SE, %)
Eyes closed Eyes open Eyes closed Eyes open
23.9 ± 3.5* 2.4 ± 0.2 60.8 ± 2.4* 26.0 ± 1.7
  1. *paired t-test, eyes closed vs. eyes open, P < .0001.
  2. aRelative power density = {absolute power density of the alpha band (8.0–12.9 Hz)}/{absolute power density of the global EEG band (2.0–30.0 Hz)} × 100 (%).
