Using G bands, some homologies between the chromosomes of Cebus apella (CAP) and human chromosomes are difficult to establish. To solve this problem, we analyzed these homologies by fluorescence in situ hybridization using human whole chromosome probes (ZOO-FISH).

AbstractA monoclonal antibody raised against the receptor for nerve growth factor (NGF) was used to examine the distribution and morphology of NGF receptor‐containing neurons within the central nervous system of Cebus apella monkeys. Most somata demonstrating positive immunoreactivity were localized within the Ch1–4 regions of the basal forebrain ...

AbstractYoung primates have relatively large hands and feet for their body size, perhaps enhancing grasping ability. We test the hypothesis that selection for improved grasping ability is responsible for these scaling trends by examining the ontogeny of intrinsic hand and foot proportions in capuchin monkeys (Cebus albifrons and Sapajus apella).

AbstractThe morphology of horizontal cells was studied in the retina of dichromatic capuchin monkeys, Cebus apella. The cells were labeled with the carbocyanine dye, 1,1′,dioctadecyl‐3,3,3′,3′‐tetramethylindocarbocyanine perchlorate (DiI), and the labeling was then photoconverted to a stable product by using a diaminobenzidine reaction.

The distrubution of CA neurons of areas A6 and A4 was delineated in Cebus apella monkey using the fluorescent histochemical technique of Falck and Hillarp. Cytospectroscopy was utilized for CA differentiation. The noradrenergic cellular regions A6, A4, and subcoeruleus have extensively increased in size in the Cebus as compared to the rat and appear to

The suprachiasmatic nucleus, an essential diencephalic component of the circadian timing system, plays a role in the generation and modulation of behavioral and neuroendocrine rhythms in mammals. Its cytoarchitecture, neurochemical and hodological characteristics have been investigated in various mammalian species, particularly in rodents.

The expression of glutamate decarboxylase forms, GAD-65 and GAD-67, in GABAergic cells was studied by immunocytochemistry in the retina of the New World monkey, Cebus apella. In the innermost rows of the inner nuclear layer (INL), somata that express GABA correspond to about 45% of the total number of cells in the central retina and about 25% on ...

Female Choice and Mating System of the Brown Capuchin Monkey Cebus apella (Primates: Cebidae)
Zeitschrift für Tierpsychologie, 1984Abstract and SummaryThe mating system of wild brown capuchin monkeys, Cebus apella, was studied during four years in Peruvian rainforest. The most striking feature of estrus is active continuous solicitation of males by females. During the first three to four days, the female continuously follows the dominant male of the group, approaching him with ...

We have evaluated several effects of intravenous administration of synthetic platelet-activating factor (PAF) in the non-human primate Cebus apella. Parameters measured were hemoconcentration (monitored by changes in hematocrit), thrombocytopenia (platelet counts), leukopenia (loss of buffy coat), bronchoconstriction (increased airway resistance to ...

AbstractDifferences in facial skeletal form arise in part through differences in growth and in part through differences in embryonic patterning and proportioning. This study examines post‐natal facial growth, sexual dimorphism and adult differences within and between two primate species:Cebus apellaandCercocebus torquatus.
