RHYTHMIC PROCESSES OF RENAL BLOOD FLOW AUTOREGULATION AND THEIR INTERACTION IN THE FORM OF MODULATION OF OSCILLATIONS

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.
