Mutual information between heart rate variability and respiration for emotion characterization.
Valderas MT, Bolea J, Laguna P, Bailón R, Vallverdú M. Valderas MT, et al. Among authors: laguna p. Physiol Meas. 2019 Sep 3;40(8):084001. doi: 10.1088/1361-6579/ab310a. Physiol Meas. 2019. PMID: 31292285
MAIN RESULTS: The results revealed that the AMIF applied to the RR time series filtered in the [Formula: see text] band was able to discriminate between the following: relax and joy and fear, joy and each negative valence conditions, and finally fear and sadness and anger, all wi …

Photoplethysmography pulse rate variability as a surrogate measurement of heart rate variability during non-stationary conditions.
Gil E, Orini M, Bailón R, Vergara JM, Mainardi L, Laguna P. Gil E, et al. Among authors: laguna p. Physiol Meas. 2010 Sep;31(9):1271-90. doi: 10.1088/0967-3334/31/9/015. Epub 2010 Aug 11. Physiol Meas. 2010. PMID: 20702919 Clinical Trial.
Time-invariant HRV and PRV indices showed no statistically significant differences (p > 0.05) and high correlation (>0.97). Time-frequency analysis revealed that the TF spectra of both signals were highly correlated (0.99 +/- 0.01); the difference between the instant …
