Synchronization, Kinematic Waves and Spike-Phase-Separation in Feedback Ising Neural Networks on Heterogeneous Graphs
Anna Poggialini, Irem Topal, Fabrizio Lombardi +1
The paper analyzes how structural heterogeneity in neural networks influences collective dynamics, showing that degree variability can trigger synchronized oscillations via a Hopf…
Early psychosis shows deviations in scaling behaviour within a critical regime
Irem Topal, Paola Moreno Ancalmo, Guillermo Montana 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…
Machine learning for cerebral blood vessels' malformations
Irem Topal, Alexander Cherevko, Yuri Bugay +5
Cerebral aneurysms and arteriovenous malformations are life-threatening hemodynamic pathologies of the brain. While surgical intervention is often essential to prevent fatal outcom…
