Synchronization, desynchronization, and resynchronization as mechanisms for the formation of variable polyrhythmicity in biological and geophysical systems

Abstract

The variable polyrhythmicity observed in natural, technical, and humanitarian spheres can be the result of mutual desynchronization of conjugate rhythmic processes. One example of desynchronization in medicine is fibrillations of heart ventricles. To bring a patient out of this state, electroshock is applied, which frequently leads to defibrillation and recovery of normal heart rhythm (resynchronization). This phenomenon has analogies in other fields of science. It is known that lunar–solar tides cause subsurface seismic noise. We give an example of detecting such noise in the Ashkhabad seismic survey area. This noise can appear and disappear, and the reason may be certain shock impacts, in particular, earthquakes. Similar results have been obtained in studying lunar seismicity, where tidal phenomena are more strongly pronounced than on Earth.
