Study Results from Russian Academy of Sciences Broaden Understanding of Hematology (Comparative Pairwise Analysis of the Relationships Between Physiological Rhythms Using Synchrosqueezed Wavelet Transform, Phase Dynamics Modelling and Recurrence).

A study conducted by the Russian Academy of Sciences in St. Petersburg explores the application of nonlinear dynamics methods to analyze interactions in biological rhythms related to the respiratory, cardiovascular, and nervous systems. The researchers found phase synchronization between blood pressure and respiratory fluctuations in response to external pain stimulation. They also observed a predominantly unidirectional influence of respiratory rhythm fluctuations on blood pressure variability, as well as a bidirectional relationship between neuronal and blood pressure variability. The study concludes that the time of influence of blood pressure variability on neuronal variability is reduced compared to the reverse. This research has been peer-reviewed and provides valuable insights into the relationships between physiological rhythms. [Extracted from the article]
