Evaluation of circadian oscillation of the autonomic nervous system by spectral analysis of heart rate variability

K. Nagatsuka; S. Senda; S. Sakamoto; T. Takagi; H. Matsuo; Y. Nitta; T. Inage; H. Yokoi; H. Suekane; K. Kawanishi; T. Nishimura [Proceedings 1992] IEEE International Conference on Systems Engineering, 1992

The authors studied whether the circadian oscillation of the autonomic nervous system can be evaluated by analysis of heart rate variability derived from 24-hour ambulatory electrocardiograms (Holter ECGs) on healthy subjects, diabetic patients, and hypertensive patients. While the circadian oscillation of the autonomic nervous system was distinct in healthy subjects, it almost disappeared in diabetic patients. Furthermore, the circadian oscillation ...


Optimal circadian rhythm control with light input for rapid entrainment and improved vigilance

Jiaxiang Zhang; John T. Wen; Agung Julius 2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012

Circadian rhythm is the biological process critical to the well being of all living organisms. The circadian rhythms oscillate with a period of approximately 24 hours due to the light-darkness pattern of the solar day. Circadian disruption, as experienced by night shift workers, travelers, submariners or miners, can lead to lower productivity, sleep disorder, and other more serious health problems. ...


Entrainment Control of Phase Dynamics

Wei Qiao; John T. Wen; Agung Julius IEEE Transactions on Automatic Control, 2017

First order phase reduced model is a good approximation of the dynamics of forced nonlinear oscillators near its limit cycle. The phase evolution is determined by the unforced frequency, the forcing term, and the phase response curve (PRC). Such models arise in biological oscillations such as in circadian rhythm, neural signaling, heart beat, etc. This technical note focuses on the ...


Cerebral temperature varies across circadian phases in humans

Philippe Boudreau; Ari Shechter; Andre Dittmar; Claudine Gehin; Georges Delhomme; Ronald Nocua; Guy Dumont; Diane B. Boivin 2008 30th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2008

The 24-hour rhythm of core body temperature (CBT) is commonly used in humans as a tool to assess the oscillation of the central endogenous circadian pacemaker. The invasive nature of the rectal sensor used to collect CBT makes it difficult to use in ambulatory conditions. Here we validate the use of a newly developed brain temperature (BT) sensor against that ...


Endogenous circadian control of the human autonomic nervous system

M. F. Hilton; M. U. Umali; C. A. Czeisler; J. K. Wyatt; S. A. Shea Computers in Cardiology 2000. Vol.27 (Cat. 00CH37163), 2000

To determine if an endogenous circadian rhythmicity, independent from sleep/wake cycles, exists in autonomic nervous system (ANS) function, heart rate variability analysis of electrocardiogram R-R intervals was applied to data collected during, a 27-day forced desynchrony protocol. Results during wakefulness indicate that the circadian pacemaker may control both the sympathetic and vagal limbs of the ANS. Vagal tone was maximal ...
