“…Generally agreement rates between actigraphic assessements and traditional polysomnographic (PSG) measures are above 90 percent and considered a valid index of human sleep (Sadeh et al, 1995; Kushida et al 2001). Although no studies have yet reported validation of actigraphy with PSG recordings in monkeys, several studies have used actigraphy to measure 24h activity in nonhuman primates as well (Zhdanova et al, 2002; Sri Kantha and Suzuki, 2006) and comparison with video-taped behavior has found good correlation between actigraphic measures and whole body movements in rhesus monkeys (Papailiu, 2007). This indicates that actigraphic methods are a good way of determining gross behavioral states such as mobility and immobility in rhesus monkeys and when combined with scoring algorithms provide a reasonable estimate of sleep and wake states.…”

Monkeys separated from their mothers soon after birth and raised with peers display many disturbances in emotional behavior that are similar to human mood and anxiety disorders. In addition to emotional disturbances, both mood and anxiety disorders are often characterized by disruptions in normal sleep-wake cycles, a behavior that has not been well characterized in adversely-reared nonhuman primates. Because polysomnographic measures are difficult to obtain in unrestrained monkeys we used 24-hour actigraphy measures to assess probable sleep-wake patterns in juvenile nursery-and mother-reared rhesus macaques (Macaca mulatta, N=16) over several days in the home cage. In addition we assayed plasma cortisol in the morning, afternoon, and evening. Relative to mother-reared (MR) monkeys, actigraphic algorhithms indicated that nursery-reared (NR) animals had shorter durations of nocturnal sleep, earlier morning waking, and longer periods of sleep during the active period, specifically in the mid morning. No shift in diurnal patterns of cortisol was observed, but NR animals displayed an overall elevation in cortisol. Finally a significant interaction was found between cortisol and actigraphic determination of sleep efficiency in the two groups. A strong positive relationship (r 2 > 0.8) was found between mean cortisol levels and sleep efficiency for the MR monkeys, but a significant negative relationship was found between these same variables for the NR monkeys, indicating a fundamentally different relationship between waking cortisol and actigraphy patterns in these two groups.

“…However, in terms of modeling human behavior rodents differ significantly from humans as they tend to eat throughout the 24 hour period with more meals focused during the night active cycle than during the day [Rushing et al, 1997]. Marmosets much more closely resemble humans in the fact that they have a true night time fast, with no consumption occurring at night [Rylands, 1996; Sri Kantha & Suzuki, 2006]. Our data suggests that the importance of the first meal of the day is relevant for marmosets as well, with the first meal of the day following the overnight fast setting the pace for overall consumption of the day with longer first meals being associated with both higher total number of counts for the day and higher counts per hour.…”

The ability to measure and interpret variables associated with feeding behavior and food intake is essential to a variety of nonhuman primate study modalities. The development of a technique to accurately and efficiently measure food intake and meal patterning in captivity will enhance both the interpretation of foraging behavior in the wild as well as our ability to model clinically relevant human feeding pathologies. In this study we successfully developed the use of a rodent lickometer system to monitor meal patterning in captive common marmosets. We describe the modifications necessary for this type of instrumentation to be used successfully with marmosets. We define variables of interest that relate to both previous rodent literature and human clinical measures. Finally, we relate our findings to potential translational value for both primate field research and biomedical applications.

“…During times of wakefulness the marmoset interacts socially with other conspecifi cs, moves around, feeds, and keeps safe from predators, while during the rest period it is predominantly asleep with brief arousals (Sri Kantha and Suzuki 2006 ). During the night, the marmosets stay on trees in protected conditions, whereas during the day they are moving in search of food, showing alertness to situations considered dangerous, such as a predator attack (Muggleton et al 2005 ).…”
