The Claustrum in the Squirrel Monkey
The Anatomical Record, 2019ABSTRACTThe claustrum (CLA) is a subcortical structure that is reciprocally and topographically connected with the cerebral cortex. The complexity of the cerebral cortex varies dramatically across mammals, raising the question of whether there might also be differences in CLA organization, circuitry, and function. Species variations in the shape of the

Saimiri sciureus (Squirrel monkey)
1973The karyotypes shown are a gift of Dr. T. C. Jones (New England Regional Primate Research Center, Southborough, Massachusetts) and were prepared from lymphocyte cultures. The two recognized phenotypes also differ in karyotype: the male came from Leticia (Colombia), and the female, from Iquitos (Peru).

Statoconia Displacement in Squirrel Monkey Ears
ORL, 1985When findings in squirrel monkey temporal bones after streptomycin sulfate intoxication were compared with those after application of intense linear acceleration, the dislocated utricular statoconia were more frequently found around the cupula of the crista ampullaris posterior in the latter group, whereas statoconia were rather widely disseminated ...

1985
Communication in the squirrel monkey, Saimiri sciureus has been the subject of numerous analyses over the past two decades. One of the interesting aspects of having participated in some of these studies has been the realization that, even in this well-studied species, there are significant gaps in understanding the functional significance, ontogeny ...

Archives of Otolaryngology - Head and Neck Surgery, 1966
The squirrel monkey is ideal for experimental tympanoplasty and stapes surgery. The anatomy of this animal's ear is quite similar to that of a human infant. In addition, its usefulness is attributable to the following reasons: (1) availability; (2) the external auditory canal is relatively straight not tortuous as in most laboratory animals, including

Orthocephalization in the postweaning squirrel monkey
American Journal of Physical Anthropology, 1996Twenty male squirrel monkeys (Saimiri sciureus boliviensis) raised in captivity were allotted to one of the following groups: weanling control (C6) sampled at 6 months of age; young control (C24) fed ad libitum on a control diet and killed at 24 months of age; and malnourished (M24) fed ad libitum on a low-protein diet and sampled at 24 months of age ...

Chondrosarcoma, Squirrel Monkey
1993An adult male squirrel monkey with severe bilateral exophthalmia and conjunctivitis was euthanatized. Necropsy revealed, in a sagittal section of the head (Fig. 135), a gray-white mass involving the nasal bone and filling the frontal and sphenoid sinuses, the anterior cranial fossa, and much of the nasal cavity.

Vigilance during play in squirrel monkeys
American Journal of Primatology, 1989AbstractPlay by young squirrel monkeys (Saimiri boliviensis) may put them and other troop members at risk for predation because youngsters are noisy, separated from adults, and not vigilant when at play. In a study using separated groups of adults and 1‐year‐old juveniles caged outdoors, we found that adult female squirrel monkeys become more vigilant ...

Cobalt epilepsy in the squirrel monkey
Electroencephalography and Clinical Neurophysiology, 1970Abstract Small amounts of cobalt powder will generate paroxysmal activity for 48–72 h in the unanesthetized squirrel monkey cortex. Using halothane anesthesia with a rapid recovery time, paroxysmal activity may begin within 30 min of cobalt application.

Observational Learning in the Squirrel Monkey
Perceptual and Motor Skills, 1963adult males, who were estimated co be 5 yr. old and had served in a variety of learning set experiments, served alternately as demonstrator ( D ) and observer (0) for 150 problems. In design the apparatus closely approximated that described by C. L. Darby and A. J. Riopelle (Observational learning in the rhesus monkey. I. comp . physiol. Psychol.. 1959,
