A CIRCADIAN TEMPERATURE RHYTHM IN THE RHESUS MONKEY.

Abstract

A rhesus monkey was restrained and kept isolated from normal laboratory distractions for 4 months. Environmental and subcutaneous temperatures were recorded every 15 minutes throughout this time. A circadian rhythm of subcutaneous temperature, whose frequency was synchronized to the 24 hour light-dark cycle, was demonstrated. The effects of constant illumination and of different feeding times were also studied. It was found that the subcutaneous temperature rhythm can be maintained under constant illumination and also that the shape of the daily curve, for this rhythm, can be effectively modified by manipulating feeding time.
