Figure 6. Activity analysis of the baboons. Representative actograms of the adult (A) and aged baboons (B) from the actiwatch analysis. The actograms demonstrate the activity of baboons during a period of 72 hrs. Sleep quality parameters were quantified from the night-time activity analysis. (C) Percent sleep time, (D) Percent awake time, (E) Sleep efficiency, (F) Sleep bouts and (G) Fragmentation index. No significant differences were observed between the two groups in sleep quality parameters. The actogram data was also used to quantify movement parameters like (H). Time spent moving during sleep, (I) Average nocturnal activity, (J) Daily nocturnal activity, (K) Average diurnal (day time) activity and (L) Daily diurnal (day time) activity. No significant (ns) differences were seen between the groups in the movement parameters.
