Oxytocin and social gaze during a dominance categorization task in tufted capuchin monkeys

Frontiers in Psychology, 2022
Visual attention to facial features is an important way that group-living primate species gain knowledge about others. However, where this attention is focused on the face is influenced by contextual and social features, and emerging evidence in Pan ...

Cyto-, myelo- and chemoarchitecture of the prefrontal cortex of the Cebus monkey

BMC Neuroscience, 2011
Background According to several lines of evidence, the great expansion observed in the primate prefrontal cortex (PfC) was accompanied by the emergence of new cortical areas during phylogenetic development.

Utilisation des sécrétions de myriapodes chez les lémurs et les sapajous : fonction curative ou signalisation sociale ?

Revue de Primatologie, 2011
Body-rubbing with millipedes is repeatedly documented in primates living under natural conditions, mainly in capuchin monkeys (Cebus spp.). Various functional (zoopharmacognosy, ingestion, social) and non-functional hypotheses (sensory, auto stimulation)

Impact of lactation upon fertility in the New World primate capuchin monkey (Cebus apella)

Journal of Medical Primatology, 2000
In the present paper, we have studied the impact of lactation upon fertility in the capuchin monkey, Cebus apella, under laboratory conditions. Nursing females (ten females, 12 postpartum periods) presented lactational amenorrhea (first menses at 159.2±9.0 vs 42.6±5.8 days postpartum in five non‐nursing females, seven postpartum periods).

Dissecting the mechanisms of squirrel monkey (Saimiri boliviensis) social learning [PDF]

PeerJ, 2013
Although the social learning abilities of monkeys have been well documented, this research has only focused on a few species. Furthermore, of those that also incorporated dissections of social learning mechanisms, the majority studied either capuchins ...

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

The Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Monkeys (Macaca mulatta and Cebus apella) and human adults and children (Homo sapiens) compare subsets of moving stimuli based on numerosity

Frontiers in Psychology, 2011
Two monkey species (Macaca mulatta and Cebus apella) and human children and adults judged the numerousness of two subsets of moving stimuli on a computer screen. Two sets of colored dots that varied in number and size were intermixed in an array in which

Impacted Bones: Can Extant Primates Help Identify Tool Use in Early Hominins?

Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 3, September 2026.
ABSTRACT Despite recent advances pushing back the earliest record of tool use, how and when it first emerged in hominins, and the extent to which it featured amongst the numerous co‐existing species, remain critical questions in paleoanthropology. In addition to analyzing fossils and lithic toolkits, novel strides in understanding this might be made by

Claustrum projections to prefrontal cortex in the capuchin monkey, Cebus apella.

Frontiers in Systems Neuroscience, 2014
We examined the pattern of retrograde tracer distribution in the claustrum following intracortical injections into the frontal pole (area 10), dorsal (area 9), and ventral lateral (area 12) regions of the rostral prefrontal cortex in the tufted capuchin ...

Occurrence of Antibodies Anti‐Toxoplasma gondii in Captive Non‐Human Primates From Pernambuco State, Brazil

Journal of Medical Primatology, Volume 55, Issue 4, August 2026.
ABSTRACT Wildlife captive populations are important tools for threatened species conservation, and early identification of diseases must be prioritized. In this study, we test for the presence of anti‐Toxoplasma gondii antibodies in non‐human primates at a Zoo from Pernambuco State, Brazil.
