Power and level of consciousness.

Comparison of the period (baseline, 3 or 6 μg/ml concentrations or recovery) with the lowest mean level of power (estimated from the entire LFP epoch of 2 minutes and averaged across animals) observed when the animal is conscious with the concentration with highest mean spectral power observed during unconsciousness (9 μg/ml in all instances). mean±stdCI: 95% confidence interval of the difference pair-wise difference of log power; p adj: p values adjusted for multiple (8) comparisons with Hommel's; # Significant difference but in opposite direction (power during 9 μg/ml higher than during baseline); p values of 0.05 or less are in bold italics.Power and level of consciousness.
