Noise-induced synchronization and regularity in feed-forward-loop motifs

Abstract: In complex systems, the interplay between network structure and noise often leads to emergent phenomena. This study explores the effects of uneven coupling and asymmetric noise on the dynamics of feed-forward loop (FFL) motifs, essential components of networks. We investigate how these variations in network motifs influence noise-induced synchrony and regularity. Using mathematical models and simulations, we uncover that the interaction of asymmetric noise and uneven coupling can significantly impact the behavior of FFL motifs, promoting synchronization and enhancing output regularity. These findings contribute to a deeper understanding of the role of network motifs in shaping network dynamics, shedding light on the intricate interplay between structure, noise, and emergent behavior in complex systems.
