Partial Synchronization in 2-Community Networks

Part of the Springer Theses book series (Springer Theses)


Large interconnected systems built from individual nodes with complex dynamics are common in many seemingly distinct fields of natural sciences, technology, and economy. We analyze partial synchronization patterns in a network of FitzHugh-Nagumo oscillators with empirical structural connectivity measured in healthy human subjects. We report a dynamical asymmetry between the hemispheres, induced by the natural structural asymmetry. We show that the dynamical asymmetry can be enhanced by introducing the inter-hemispheric coupling strength as a control parameter for partial synchronization patterns. We specify the possible modalities for existence of unihemispheric sleep in human brain, where one hemisphere sleeps while the other remains awake.
