Ambulatory long-term monitoring of brain temperature

Abstract : This paper aims at presenting the first results of long-term monitoring of brain temperature using a non-invasive ambulatory device, the Brain and Core Thermometer (BCT), whose operating principle relies on the zero-heat-flow method. The experiment presented in this paper is part of the study “Monitoring Human Circadian Physiology through Real-Time State Estimation” led by the Centre for Study and Treatment of Circadian Rhythms, Douglas Mental Health University Institute in Montreal, Canada. The main purpose of this study is the development of new methods for circadian phase monitoring in field operations. The results are for two subjects monitored for about 30 consecutive hours. BCT measurements are compared with the rectal temperature using the Bland-Altman method. The bias of the BCT sensor was -0.029 °C, with 95 % limits of agreement at −0.38 and +0.35 °C. These results are promising, making the BCT, a suitable device for circadian rhythm studies.
