Studying Electrocorticograms Based on the Concept of Rhythms Coordination

Abstract: Rhythms are known in the nervous system for a long time, but there are still open questionsconcerning functions they serve. Recently, a new paradigm of network interactions of physiologically significant cortical rhythms hasbeen proposed and various classes of coupling forms have been discovered that coexist during a certain physiological stateand reorganize during transitions between physiological states. In particular, it has been demonstrated that physiological states cannot befully described by focusing only on individual rhythms. In this study, cross-correlations of cortical rhythms are considered for different physiological states with a modified version of fluctuation analysis. Distinctions in the cross-correlations of pairs of rhythms are reported caused by sleep deprivation in mice.

Speaker: Alexey Pavlov is a Professor of the Department of Open Systems Physics at the Saratov State University. He received M.S. in Radiophysics in 1995, Ph.D. in 1998, and D.Sc. in 2009 also in Radiophysics from the Saratov State University, Russia. His research interests are in signal processing, dynamics of living systems, theory of oscillations, neuroscience, nonlinear dynamics and its applications in biology and medicine. A. Pavlov is a co-author of more than 250 peer-reviewed publications, including the book “Wavelets in Neuroscience”, Springer 2015 (1-st ed.) and 2021 (2-nd ed.). He was supervisor of 9 PhD-students.
