Abstract

We discuss entrainment phenomena in the regulation of cerebral and peripheral blood flow in newborn rats under normal conditions and during pathological changes in the dynamics of blood vessels accompanying the development of stroke. Using a wavelet-based coherence measure, we analyze the degree of interrelation between the dynamics of blood flow in the sagittal sinus, the surrounding network of small vessels, as well as in the artery and vein of the neck. We show that the coherence measure reflects changes in the entrainment at the latent stage of stroke formation.
