Per3 expression in different tissues of Cebus apella [PDF]
Sleep Science, 2016 We present a study of Per3 expression in six different tissues of the non-human primate Cebus apella (capuchin monkey). The aim of this study was to verify whether the expression of the Per3 gene in different tissues of capuchin monkey occurs in a ...

Methodological Considerations in the Analysis of Fecal Glucocorticoid Metabolites in Tufted Capuchins (Cebus apella). [PDF]
Int J Primatol, 2013 Analysis of fecal glucocorticoid (GC) metabolites has recently become the standard method to monitor adrenocortical activity in primates noninvasively. However, given variation in the production, metabolism, and excretion of GCs across species and even ...

Experimental gastric carcinogenesis in Cebus apella nonhuman primates. [PDF]
PLoS One, 2011 The evolution of gastric carcinogenesis remains largely unknown. We established two gastric carcinogenesis models in New-World nonhuman primates. In the first model, ACP03 gastric cancer cell line was inoculated in 18 animals. In the second model, we treated 6 animals with N-methyl-nitrosourea (MNU).

Give what you get: capuchin monkeys (Cebus apella) and 4-year-old children pay forward positive and negative outcomes to conspecifics. [PDF]
PLoS One, 2014 The breadth of human generosity is unparalleled in the natural world, and much research has explored the mechanisms underlying and motivating human prosocial behavior.

The stone tools of capuchins (Cebus apella) [PDF]
International Journal of Primatology, 1995 We examined the production of stone took by capuchins (Cebus apella). Eleven subjects used five reduction techniques to produce 346 stone tools (48 cores and 298 flakes). They produced a sharp edge on 83% of the cores and largest flakes. Three monkeys later used a sample of these objects as cutting tools.

Scanning electron microscopy study of the choroid plexus in the monkey (Cebus apella apella) [PDF]
Arquivos de Neuro-Psiquiatria, 2000 The cells of the choroid plexus of the lateral ventricles of the monkey Cebus apella apella were examined through scanning electron microscopy at contributing to the description of such structures in primates.

Do lemurs know when they could be wrong? An investigation of information seeking in three species of lemur (Lemur catta, Eulemur rubriventer, and Varecia variegata) [PDF]
, 2020 Sixteen lemurs, including representatives from three species (Lemur catta, Eulemur rubriventer, Varecia variegata), were presented with a food seeking task where information about the rewards location, in one of two plastic tubes, was either known or not

Are capuchin monkeys (Cebus apella) inequity averse? [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2006 It has been reported that capuchin monkeys reject a less preferred food (LPF) when they see a partner capuchin receive a more preferred food (PF) for performing the same task. This behaviour was taken as evidence of ‘inequity aversion’, but an alternative hypothesis is that capuchins reject the LPF because of the mere presence of the PF. We tested this
