Stone tools differences across three capuchin monkey populations: food’s physical properties, ecology, and culture [PDF]
Robust capuchin monkeys (Sapajus) are known for processing mechanically challenging foods, having morphological adaptations to do so. However, several populations go beyond body limitations by using stone tools to expand their food range.

A novel nonsense mutation in the tyrosinase gene is related to the albinism in a capuchin monkey (Sapajus apella) [PDF]
Background Oculocutaneous Albinism (OCA) is an autosomal recessive inherited condition that affects the pigmentation of eyes, hair and skin. The OCA phenotype may be caused by mutations in the tyrosinase gene (TYR), which expresses the tyrosinase enzyme ...

Nut-cracking success and efficiency in two wild capuchin monkey populations [PDF]
Capuchins can employ several strategies to deal with environmental challenges, such as using stone tools to access encapsulated resources. Nut-cracking is customary in several capuchin populations and can be affected by ecological and cultural factors ...

Anatomical analysis of thumb opponency movement in the capuchin monkey (Sapajus sp). [PDF]
Capuchin monkeys present a wide variety of manipulatory skills and make routine use of tools both in captivity and in the wild. Efficient handling of objects in this genus has led several investigators to assume near-human thumb movements despite the ...

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

Bearded capuchin monkeys as a model for Alzheimer’s disease [PDF]
The absence of a natural animal model is one of the main challenges in Alzheimer’s disease research. Despite the challenges of using nonhuman primates in studies, these animals can bridge mouse models and humans, as nonhuman primates are phylogenetically

Fairly flexible: brown-tufted capuchins and a squirrel monkey adjust their motor responses in a foraging task [PDF]
Prior research on non-human primates has produced contradictory results regarding behavioral flexibility and habit formation. Most observational studies of wild primates show flexibility in foraging behavior, whereas experimental data suggest captive ...
