Fetal development assessed by self-organization indices

Event Abstract Back to Event Fetal development assessed by self-organization indices Dirk Hoyer1* and Schneider Uwe2 1 Friedrich Schiller University Jena, University Hospital, Biomagnetic Center, Germany 2 Friedrich Schiller University Jena, University Hospital, Dept. of Obstetrics, Germany The fetal precursors of mental and cardiovascular disease in later age are an important issue of developmental medicine. We investigate the question whether key parameters of fetal development reflect self-organization principles. From the systems theoretical point of view self-organization means the evolution of a previously less organized system into a higher organized form in the absence of external control. This process is characterized by a move from a large region of state space to a persistent smaller one, under the control of the system itself, and the development of correlations over time or space for previously independent locally operating variables. The object of the present work is to describe associations between the development of fetal heart rate patterns and characteristics of self-organization. From 78 normal fetuses, gestational age 23-40 weeks, heart beat interval series of 30 min duration were recorded by magnetocardiography. As indices of fetal development several characteristics which are typically associated with self-organization were analyzed. With development the variability of heart rate, the number of acceleration, and autonomic information flow over large time scales increased. These features are associated with essential self-organization characteristics, namely necessary variability, loss of degrees of freedom, and emergence of global order. Heart rate characteristics interpreted following the systems theoretic concept of self-organization may provide new insights into the fetal development with implications for more appropriate diagnosis and prenatal treatment.
