Visual acuity of “Saimiri sciureus” [PDF]
Psychonomic Science, 1965 The visual acuity of the squirrel monkey was studied by the method of least separable lines. Five animals were studied in two different apparatuses by two different experimenters. Thresholds of 75% correct were established at 0.84 min. of visual angle. Decline in correct responses was well coordinated with increasing latency of response.

Hemodynamic molecular imaging of tumor-associated enzyme activity in the living brain
eLife, 2021 Molecular imaging could have great utility for detecting, classifying, and guiding treatment of brain disorders, but existing probes offer limited capability for assessing relevant physiological parameters.

The mechanism of labor in nonhuman primates: A look inside
The Anatomical Record, EarlyView.Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

Molecular data highlight hybridization in squirrel monkeys (Saimiri, Cebidae)
Genetics and Molecular BiologyHybridization has been reported increasingly frequently in recent years, fueling the debate on its role in the evolutionary history of species. Some studies have shown that hybridization is very common in captive New World primates, and hybrid offspring ...
