Application of double-wavelet analysis to study modulation phenomena in dynamics of nephrons
Based on the double-wavelet analysis, the paper proposes a method to study interaction phenomena of rhythmic components in nonstationary multimode dynamics. Possibilities and limitations of the approach are illustrated for a number of test examples. Application of the double-wavelet analysis is considered for tubular pressure signals from rat nephrons in order to quantify the modulation phenomena of the fast (myogenic) dynamics of nephrons by the slow rhythm caused by the tubulo-glomerular feedback mechanism. It is shown that interaction between the two mechanisms is stronger in hypertensive rats than in normotensive rats.
