Renal blood flow autoregulation at the level of individual nephrons includes two interacting mechanisms that produce oscillations with different time scales: the tubologlomerular feedback (TGF) and the myogenic response. Based on the waveletanalysis of experimental data, we study in this work phenomena of amplitude and frequency modulation of myogenic oscillations by the TGFrhythm. Features of nonlinear dependencies of amplitude and frequency deviation of modulated process versus the amplitude of modulating oscillations are revealed. It is shown that phenomena of modulation are essentially different between normal and hypertensive states.
