Investigation of the sleep electrocorticogram of the common marmoset (Callithrix jacchus) using radiotelemetry

OBJECTIVE: To evaluate the use of a totally implantable radiotelemetry system for recording the sleep electrocorticogram (ECoG) of a small new world primate, the common marmoset (Callithrix jacchus) without restraint during data collection. METHODS: Under anaesthesia a telemetry transmitter, which allowed the recording of a single ECoG channel, was implanted intraperitoneally. This system allowed ECoG […]

Differential effect of early enrichment and deprivation on learning in the rhesus monkey (Macaca mulatta)

Data are presented to both support and extend research findings concerning the effects of early experience on nonhuman primate learning ability. Enriched monkeys tested in their home living environment performed more proficiently than monkeys separated from their living environments and tested in an adjoining room. Further, monkeys reared in enriched environments were superior to partially […]

Mate choice in non-human primates

Mate choice has been observed in many species of non-human primates. There are few definitive studies, however, due to the long life spans, complex social behavior, and cognitive abilities of these animals. Here I review the current literature on mate choice in primates. Females typically prefer complex behavioral traits such as social status, familiarity, personality, […]

Personality as a Predictor of General Health in Captive Golden Snub-Nosed Monkeys (Rhinopithecus roxellana)

Increasing studies in human and animals have shown that personality is related to biological profile and affects health outcomes. Understanding the link between personality and health will contribute to preventing illness and promoting well-being in non-human primates. The present study examined whether personality predicted health outcomes in captive golden snub-nosed monkeys (Rhinopithecus roxellana). Personality was […]
