Physics of neural networks with non-additive coupling
Zusammenfassung der Projektergebnisse
We believe that the incorporation of mechanisms of nonadditivity represents a new direction of research in the physics and network science of neural systems, e.g. for exploring guided synchrony as well as promoting and exploiting oscillations. By example of oscillations emerging in hippocampus, we thereby also link local non-additive coupling and networkwide oscillations to a specific functional role (memory formation and recovery). On a side note, some of the theoretical tools we have developed in this work, in particular the effective description of statistical impingements of pulses in the presence of non-additivities and the newly uncovered potential of hub units to indirectly control signal propagation should also apply to broader settings beyond neuronal networks, e.g., in networks of interacting flashing fireflies or technical pulse-coupled systems.
