Synchronization, Kinematic Waves and Spike-Phase-Separation in Feedback Ising Neural Networks on Heterogeneous Graphs
Anna Poggialini, Irem Topal, Fabrizio Lombardi +1
Structural heterogeneity constrains collective dynamics in complex systems. However, its analytical tractability out of equilibrium remains limited. In this work, we study a class…
Early psychosis shows deviations in scaling behaviour within a critical regime
Irem Topal, Paola Moreno Ancalmo, Guillermo Montaña-Valverde +2
Accumulating evidence suggests that large-scale brain activity exhibits scale-invariant dynamics consistent with operation in a near-critical regime. Such dynamics have been associ…
Scaling and tuning to criticality in resting-state human magnetoencephalography
Irem Topal, Anna Poggialini, Marco Dal Maschio +3
From 1/f noise to neuronal avalanches, evidence of scaling in brain activity has been increasingly linked to tuning to or near criticality. The concept of scaling is intimately rel…
