Therefore, the percentage of activity during day or night and tau values from actograms (see below) were ultimately pooled, regardless of the method of analysis.
The actogram representations of activity visibly show the shift in activity levels after the light cycle changes.
Inspection of the actogram (not presented here) revealed a decrease in sleep disruptions for the first several nights of the valerian condition, after which however, no further improvement could be detected.
Analysis of the actogram (not presented here) indicated sleep latencies and nighttime awakenings were markedly improved from the onset of valerian treatment.
Under the LD 16:8 photoperiod in the autumn, the actogram showed a high level of nocturnal activity (Fig.
Variability in diel activity was visually represented using actograms, while the strength of rhythm was characterized with autocorrelation analysis (Dowse and Ringo, 1989; Palmer et al.
After this period of free running, actograms for each animal were independently examined by two investigators to determine activity onset.
Visual inspection of actograms similarly revealed no substantive changes in either activity levels or free-running periods under different treatment conditions.
These data were then plotted and analyzed further as actograms and Lomb-Scargle periodograms (P < 0.
