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 (THYPO), colonic (Tc), and mean skin (Tsk) temperatures, chest sweat rate (mSW), and heart rate (HR). THYPO was monitored using a thermocouple inserted to the tip of a non-perfused thermode; mSW 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 THYPO from 37 to 41 degrees C increased mSW from 0.05 to 0.30 mg.cm-2.min-1. Reducing Tsk shifted the THYPO:mSW relationship to the right (p less than 0.05) without significantly altering its slope. Activity-induced changes in HR, when THYPO was constant, caused fluctuations in ongoing sweating that closely tracked HR. We conclude that mSW in the patas monkey is controlled by both peripheral and central thermal inputs and nonthermal factors.

D012044	Regression Analysis	Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
