Relative band powers of patients with slow induction at loss of responsiveness to verbal command and painful stimulus. Course of the relative band powers for the 10 min before loss of responsiveness to verbal command (LOvR) in green and loss of responsiveness to painful stimulus (LOpR) in blue. The orange shading indicates the 95% confidence interval of the particular frequency band considering the first 10 s after LOvR or LOpR. The lower plots display the area under the curve. Black dots indicate significance. The “x” indicate the boundaries of the 95% CI. (A) The relative delta band power was significantly higher until around 300 s to 400 s before LOvR. The relative delta power decreased after LOvR. (B) The relative delta band power was significantly higher until around 200 s before LOpR, but did not decrease further after LOpR. (C) The relative theta band power was significantly lower for a short period before LOvR. (D) The relative theta band power was significantly lower for a short period before LOpR. (E) The relative alpha band power was significantly lower until around 3 min before LOvR and significantly higher after around 3 to 4 min after LOvR. (F) The relative alpha band power was significantly lower until around 2–3 min before LOpR and continued to increase after LOpR. (G) The relative beta power was significantly lower till around 300 s before LOvR. For the remainder of the observation period, it was not significantly different compared to the LOvR. (H) The relative beta power was significantly lower till around 200 s before LOpR and again starting after around 250 s 450 s LOpR.
