Percentage of NREMS (A) and REMS (B) recovered after 6 h of sleep deprivation in the Oil (solid bars), LE, HE, LP, LEP, and M (white bars) groups. The percentage was calculated by dividing the difference between NREMS or REMS amounts during the 18-h baseline and recovery periods by the duration of NREMS or REMS lost during the 6 h deprivation period. Data are shown as means + SEM (n = 7-8 per group). The percentage gain of REMS during recovery relative to lost REMS was greater in the LE and HE groups than in the Oil group, while the percentage gain of NREMS was not significantly different among groups. ^aDifferent from Oil; ^cdifferent from HE. All P < 0.05 (Fisher LSD post hoc comparisons).
