Abstract

We consider the synchronization between the dynamics of blood flow in cerebral and peripheral vessels in rats from the point of view of locking the instantaneous frequencies associated with slow oscillations caused by the neurogenic regulatory mechanism or, in part, metabolic activity. We show that the degree of synchronization varies with the development of a stroke caused by severe stress, which is reflected in the reduced average duration of segments with frequency locking. Such changes differ between macro- and microcerebral dynamics and are more pronounced for a network of small vessels surrounding the sagittal sinus.
