AB  - Pulse rate variability (PRV) can be extracted from functional near-infrared 
      spectroscopy (fNIRS) (PRV(NIRS)) and photoplethysmography (PPG) (PRV(PPG)) 
      signals. The present study compared the accuracy of simultaneously acquired 
      PRV(NIRS) and PRV(PPG), and evaluated their different characterizations of the 
      sympathetic (SNS) and parasympathetic (PSNS) autonomous nervous system activity. 
      Ten healthy subjects were recorded during resting-state (RS) and respiratory 
      challenges in two temperature conditions, i.e., room temperature (23 degrees C) and cold 
      temperature (4 degrees C). PRV(NIRS) was recorded based on fNIRS measurement on the head, 
      whereas PRV(PPG) was determined based on PPG measured at the finger. Accuracy 
      between PRV(NIRS) and PRV(PPG), as assessed by cross-covariance and cross-sample 
      entropy, demonstrated a high degree of correlation (r > 0.9), which was 
      significantly reduced by respiration and cold temperature. Characterization of 
      SNS and PSNS using frequency-domain, time-domain, and nonlinear methods showed 
      that PRV(NIRS) provided significantly better information on increasing PSNS 
      activity in response to respiration and cold temperature than PRV(PPG). The 
      findings show that PRV(NIRS) may outperform PRV(PPG) under conditions in which 
      respiration and temperature changes are present, and may, therefore, be 
      advantageous in research and clinical settings, especially if characterization of 
      the autonomous nervous system is desired.
