Fig. 3

Effect of 6-h gentle handling total sleep deprivation on REM sleep during LD12:12 (n = 6) and LD1:1 (n = 5) conditions. The figure depicts only the data of the recovery period after SD (R1–R16 hours). Panel ab: LD12:12 data, panel cd: LD1:1 data. Panel a and c: hourly average of REM sleep times during baseline (grey line) and after sleep deprivation (black line). Panel b and d: summarized amount of REM sleep at the end of the light phase (hour CT12) during the baseline LD12:12 and LD1:1 conditions and after total SD (hour R6). The column pair at the right side show summarized REM sleep time at the end of the day during baseline and after total SD. Black and white bars at the x axis show the illumination pattern in the different hours. Significance was tested with two-way ANOVA with time and treatment as factors, followed by Sidak’s multiple comparisons test. Summarized REM sleep times during the first- and in the second half of the day depicted on C and D were compared using Welch’s t-test. Significance levels: *, # - p < 0.05; **, ##- p < 0.01; ***, ### - p < 0.001. Data are expressed as mean ± S.E.M
