Demonstration of GABA immunoreactive cells in the inferior olive of baboons (Papio papio and Papio anubis)

Neuroscience Letters, 1989
The distribution of gamma-aminobutyric acid (GABA)-like immunoreactivity was studied in semithin sections through the inferior olivary complex in two baboon species. About 5% of the olivary neurons were GABA-immunoreactive. The GABA-immunoreactive neurons differed from the large majority of olivary neurons by their smaller size and their lower contents

A Note on the Birth of a Baboon (Papio anubis)

Folia Primatologica, 1978
Parturition in a baboon (Papio anubis) was observed, videotaped and described. Early signs of parturition were noted as was the behaviour of the animal as she delivered the infant.

Androgen and estrogen dynamics in the female baboon (Papio anubis)

Journal of Steroid Biochemistry, 1988
Androgen and estrogen dynamics were studied in 5 female baboons (Papio anubis) using constant infusions of [3H]androstenedione/[14C]estrone and [3H]testosterone/[14C]estradiol. Blood samples were obtained prior to the infusions and both blood and plasma was used for measurements of androstenedione (A), testosterone (T), dihydrotestosterone (DHT ...

Reciprocal altruism in Papio anubis

Nature, 1977
ALTRUISM is behaviour that benefits another individual at some cost to the altruist, costs and benefits being measured in terms of individual fitness. ‘Reciprocal altruism’ (ref. 1) implies the exchange of altruistic acts between unrelated individuals as well as between relatives.

Testicular steroidogenesis in the mature and immature baboon Papio anubis

General and Comparative Endocrinology, 1977
Abstract The following studies were undertaken to compare testicular steroidogenesis in the mature and immature baboon. Testicular fragments (50 mg) were incubated for 3 hr with [7- 3 H]pregnenolone, or with [7- 3 H]progesterone. The mature testis formed more testosterone (4.6%), androstenedione (1.6%), and progesterone (28.5%) from pregnenolone than

Electroretinographic determination of the spectral sensitivity of the baboon (Papio Anubis)

Vision Research, 1968
Abstract As a preliminary investigation of the baboon ( Papio Anubis ) visual system, ERG's were recorded using monochromatic light. The computer-averaging technique was used to enhance the signal-to-noise ratio. Scotopic responses were recorded using discrete flashes 100–200 msec in duration under dark-adapted conditions.

Male dominance and reproductive activity in Papio anubis

Animal Behaviour, 1979
The dominance relations of the sexually mature males residing in three troops of Papio anubis at Gombe National Park, Tanzania are examined and three tactics which males employed to increase temporarily their dominance against other males are discussed. The summation of the dominance relationships in each troop revealed a linear hierarchy. In immigrant

Parturition in a feral baboon (Papio anubis)

Primates, 1974
During a study of feral baboons at the Gombe Stream National Park, Tanzania, the premature birth of a dead, breechborn infant was observed and photographed. The placenta was immediately eaten and the dead infant carried by the mother for two days. The birth itself attracted little attention from other troop members, but the dead infant was investigated

Hepatocystosis in a baboon (Papio anubis).

Contemporary topics in laboratory animal science, 2001
A 26-lb wild-caught adult female baboon was obtained from a commercial vendor. Routine tests for parasites, pathogenic bacteria, and tuberculosis were negative throughout the 10-week quarantine. However, routine radiographs performed at the end of the quarantine period detected multiple small radioopaque nodules evenly dispersed throughout the liver. A

Muscle Function and Structure of the Esophagus of the Baboon (Papio anubis)

American Journal of Veterinary Research, 1978
SUMMARY A baboon (Papio anubis) was used as a model for the study of the physiology of the esophagus. This model closely resembles the human being phylogenetically and physiologically. Base-line lower esophageal sphincter pressure and peristaltic amplitude are similar to that of man.
