Abstract Cebus albifrons monkeys were used to study the relationship of the chiasmatic response evoked by light stimulation to various parameters of stimulation. The usual pattern of the gross response consisted of an early positive and a later positive-negative component which, to some extent, could be modified independently.

American Journal of Physical Anthropology, 1980
AbstractCebus albifrons and Cebus apella, partially sympatric capuchin monkeys from South America, are known to differ substantially in adult body mass and bodily proportions. C. apella possesses a robust, stocky build in contrast to the more gracile, relatively longer limbed body design of C. albifrons.

Synchronized retinal afterdischarge and neural dark adaptation in the monkey (Cebus albifrons)
Experimental Neurology, 1968Abstract The relationship between the duration of synchronized after-discharge (30/sec), recorded from the optic chiasm of monkeys following cessation of illumination, and the intensity and duration of an immediately preceding test light; intensity and duration of prior conditioning illumination; duration of dark adaptation between conditioning and ...

Ultrastructure of quiescent oocytes of Cebus albifrons.
Journal of anatomy, 1976Quiescent oocytes of the monkey Cebus albifrons were examined with the electron microscope. In many respects the ultrastructure of these cells was similar to that of other mammalian species. Elongate and oval mitochondria, lamellar Golgi complexes, small profiles of smooth endoplasmic reticulum, and vacuolar organelles were randomly distributed around ...

Physical growth of cebus monkeys (Cebus albifrons) during the first year of life.
Growth, 1975Infannt cebus monkeys, removed from their mothers shortly after birth, were reared in a primate nursery on diets of controlled nutritional quality. At regular intervals between birth and one year of age, each monkey was anesthetized, measured, and radiographed. Measurements were fitted to functions of the animal's age in days; a linear function for the

Infection of capuchin monkeys (Cebus albifrons) with Herpesvirus saimiri.
Journal of the National Cancer Institute, 1975Herpesvirus saimiri (HVS) induced persistent, clinically inapparent infections of long-term duration in capuchin monkeys (Cebus albifrons). The infections were characterized by development of antibody to HVS-associated antigens and recovery of low levels of virus-genome-carrying lymphocytes in the peripheral blood. Peripheral lymphocyte counts remained

Tool use in wild capuchin monkeys (Cebus albifrons trinitatis)
American Journal of Primatology, 1998White-fronted capuchins were observed to use leaves as cups to retrieve water from tree cavities. On multiple occasions several individuals performed this behavior. Thus, these capuchins engage in habitual tool use, as defined by McGrew's classificatory scheme of tool using behavior.

Ontogeny of muscle mechanical advantage in capuchin monkeys (Cebus albifrons and Cebus apella)
Journal of Zoology, 2005AbstractTerrestrial locomotion requires that animals maintain postural stability against the flexing force of gravity. To counteract volume/area relationships that limit muscle force and may compromise stability, larger animals increase the effective mechanical advantage of their extensor musculature by walking on more extended limbs and showing ...

Banding patterns of the chromosomes of Cebus albifrons. Comparative study with Cebur apella.
Folia primatologica; international journal of primatology, 1976Quinacrine- and Giemsa-banding studies of the chromosomes of Cebus albifrons permitted to obtain a pattern that characterizes the species. The topography of the bands has been compared with that of Cebus apella. Each chromosome pair of C. albifrons has a homologue in C. apella.
