Comparative dipolar electrocardiotopographic study of ventricular activation in Macaca mulatta monkeys and man.

Comparative susceptibility of chimpanzees and Macaca mulatta monkeys to oral administration of partially purified staphylococcal enterotoxin.

Although several species of animals have been reported to be susceptible to staphylococcal enterotoxin, Dack (1956) stated ". . . no experimental animal has been found that will react to the small amount of enterotoxin sufficient to cause severe reactions in man." Of the few animals regularly used to determine the presence of toxin in test samples of material, the Macaca mulatta monkey fed by s...

The Expression implication of GDNF in ventral horn and associated remote cortex in rhesus monkeys with hemisected spinal cord injury

Objective(s): Glial cell line-derived neurotrophic factor (GDNF) can effectively promote axonal regeneration，limit axonal retraction，and produce a statistically significant improvement in motor recovery after spinal cord injury (SCI). However, the role in primate animals with SCI is not fully cognized. Materials and Methods:18 healthy juvenile rhesuses were divided randomly into six groups, obs...

Journal of Experimental Psychology: Animal Learning and Cognition Do You See What I See? A Comparative Investigation of the Delboeuf Illusion in Humans (Homo sapiens), Rhesus Monkeys (Macaca mulatta), and Capuchin Monkeys (Cebus apella)

Can monkeys (Macaca mulatta) represent invisible displacement?

Four experiments were conducted to assess whether or not rhesus macaques (Macaca mulatta) could represent the unperceived movements of a stimulus. Subjects were tested on 2 computerized tasks, HOLE (monkeys) and LASER (humans and monkeys), in which subjects needed to chase or shoot at, respectively, a moving target that either remained visible or became invisible for a portion of its path of mo...

The composite face effect in chimpanzees (Pan troglodytes) and rhesus monkeys (Macaca mulatta).

The accurate recognition of individuals is a cornerstone of social exchange in primates. Current approaches to the study of individual recognition, however, are focused on human performance and only occasionally reference comparative research for support. A number of studies have suggested that humans can easily recognize thousands of individual faces and that this perceptual expertise is suppo...
