Abstract : In preparation for biological experiments aboard orbiting laboratories three Cebus albifrons, white-fronted capuchin monkey, were exposed to five headward-directed (+Az) resultant linear acceleration stimuli aboard a centrifuge and their ECG's, skin temperatures, and breathing rates recorded. Marked tachycardia was noted at the start of the centrifugation, followed by bradycardia within 6 to 7 minutes at 7.5 g and within 1 1/2 minutes at 10.3 g. Concomitant with the onset of bradycardia, a loud squeal was usually heard. There were no significent temperature changes, and breathing rates did not vary from normal. Normal heart rate was restored upon cessation of centrifugation. It appears that the Cebus can withstand the acceleration of space travel and therefore will be a good experimental animal in that environment. (Author)
