Abstract
Two male (10–13 kg) patas monkeys
(Erythrocebus patas) were implanted with bilateral thermodes to control hypothalamic temperature. Animals were restrained in primate chairs and instrumented to yield hypothalamic (T
HYPO), colonic (T
c), and mean skin (T̄
SK) temperatures, chest sweat rate (m
SW), and heart rate (HR). T
HYPO was monitored using a thermocouple inserted to the tip of a non-perfused thermode; m
SW was measured using resistance hygrometry. After the monkey equilibrated to a selected ambient temperature, four thermodes were perfused with water from a temperature-controlled bath. Increasing T
HYPO from 37 to 41°C increased m
sw from 0.05 to 0.30 mg.cm
−2.min
−1. Reducing T̄
SK shifted the T
HYPO:m
SW relationship to the right (
p<0.05) without significantly altering its slope. Activity-induced changes in HR, when T
hypo was constant, caused fluctuations in ongoing sweating that closely tracked HR. We conclude that m
SW in the patas monkey is controlled by both peripheral and central thermal inputs and nonthermal factors.
