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.
Under the LD 16:8 photoperiod in the autumn, the actogram showed a high level of nocturnal activity (Fig.
These values were entered into the program ActogramJ to create actograms that could be used to determine the types of rhythms expressed by individual horseshoe crabs (Schmid et al., 2011).

In addition, the entrainment by light stimuli seemed normal in the SDT fatty rats, as revealed by the observation that the SDT fatty rats exhibited the same SLA pattern over a period of 5 consecutive days of monitoring, although actograms were not measured in the present study.

Wheel revolutions were recorded electronically and automatically saved to computer for later plotting (as actograms) and periodogram analysis using the circadian analysis program 'Tau' (Schull, J., Mini-Mitter Co., Inc., Oregon, USA), utilising lines fitted to activity onsets for each phase of the experiments.
