Abstract: 

In this work, the phenomenon of synchronization of oscillations in the dynamics of nephronic ensembles is studied. It is shown that a large number of structural units on the kidney's surface participate in the formation of synchronous clusters. It is stated that the cluster's size changes in time and the frequency locking for rhythmic processes in the cooperative dynamics of nephrons occurs only during some parts of experimental recordings.
