Scale-Invariant Structures of Spiral Waves
Daniel Sohn, Konstantinos N. Aronis, Hiroshi Ashikaga
Spiral waves are considered to be one of the potential mechanisms that maintains complex arrhythmias such as atrial and ventricular fibrillation. The aim of the present study was t…
Causal Unit of Rotors in a Cardiac System
Hiroshi Ashikaga, Francisco Prieto-Castrillo, Mari Kawakatsu +1
The heart exhibits complex systems behaviors during atrial fibrillation (AF), where the macroscopic collective behavior of the heart causes the microscopic behavior. However, the r…
Inter-Scale Information Flow as a Surrogate for Downward Causation That Maintains Spiral Waves
Hiroshi Ashikaga, Ryan G. James
The mechanism that maintains atrial fibrillation (AF) remains elusive. One approach to understanding and controlling the mechanism ("AF driver") is to quantify inter-scale informat…
Hidden Structures of Information Transport Underlying Spiral Wave Dynamics
Hiroshi Ashikaga, Ryan G. James
A spiral wave is a macroscopic dynamic of excitable media that plays an important role in several distinct systems, including the Belousov-Zhabotinsky reaction, seizures in the bra…
