Noninvasive technique for the repeated sampling of salivary free cortisol in awake, unrestrained squirrel monkeys (2003)

Tiefenbacher, S., Lee, B., Meyer, J. S. et al.

Abstract

Individually housed adult male squirrel monkeys were trained to chew on dental rope attached to a pole, from which saliva was extracted by centrifugation and analyzed for cortisol. ... Eight of nine monkeys readily acquired the task, reliably providing adequatesaliva samples for the assay. ... The described sampling technique provides a reliable and sensitive means for repeated measurement of HPA activity in unrestrained, awake squirrel monkeys.
