Journal ArticleDOI
Power spectrum analysis of heart rate fluctuation: a quantitative probe of beat-to-beat cardiovascular control
TL;DR: It is shown that sympathetic and parasympathetic nervous activity make frequency-specific contributions to the heart rate power spectrum, and that renin-angiotensin system activity strongly modulates the amplitude of the spectral peak located at 0.04 hertz.
Journal ArticleDOI
Hemodynamic regulation: investigation by spectral analysis
Solange Akselrod,Deborah M. Gordon,J. B. Madwed,N. C. Snidman,Daniel C. Shannon,Richard J. Cohen +5 more
TL;DR: It is found that respiratory frequency fluctuations in HR are parasympathetically mediated and that blood pressure fluctuations at this frequency result almost entirely from the direct effect of centrally mediated HR fluctuations, and the sympathetic nervous system appears to be too sluggish to mediate respiratory frequency variations.
Journal ArticleDOI
An Efficient Algorithm for Spectral Analysis of Heart Rate Variability
TL;DR: It is demonstrated that the amplitude spectrum of this heart rate signal more closely matches that of the input signal to an integral pulse frequency modulation model of the heart's pacemaker than do the spectra of other ECG-derived heart rate signals.
Journal ArticleDOI
Passive or Active Immunization with Myelin Basic Protein Promotes Recovery from Spinal Cord Contusion
Ehud Hauben,Oleg Butovsky,Uri Nevo,Eti Yoles,Gila Moalem,Eugenia Agranov,Felix Mor,Raya Leibowitz-Amit,Evgenie Pevsner,Solange Akselrod,Michal Neeman,Irun R. Cohen,Michal Schwartz +12 more
TL;DR: The results suggest that T cell-mediated immune activity, achieved by either adoptive transfer or active immunization, enhances recovery from spinal cord injury by conferring effective neuroprotection.
Journal ArticleDOI
Fluctuations in autonomic nervous activity during sleep displayed by power spectrum analysis of heart rate variability
TL;DR: The sympathetic predominance that characterizes wakefulness decreases during non-REM sleep, is minimal in slow-wave sleep, and surges toward mean awake levels during REM sleep, while the autonomic balance is shifted toward parasympathetic predominance during slow- wave sleep.
