Stability of synchronous states in sparse neuronal networks
Afifurrahman, Ekkehard Ullner, Antonio Politi
The stability of synchronous states is analysed in the context of two populations of inhibitory and excitatory neurons, characterized by different pulse-widths. The problem is redu…
Quantitative and qualitative analysis of asynchronous neural activity
Ekkehard Ullner, Antonio Politi, Alessandro Torcini
The activity of a sparse network of leaky integrate-and-fire neurons is carefully revisited with reference to a regime of a bona-fide asynchronous dynamics. The study is preceded b…
Cortical Spike Synchrony as a Measure of Input Familiarity
Clemens Korndörfer, Ekkehard Ullner, Jordi García-Ojalvo +1
Spike synchrony, which occurs in various cortical areas in response to specific perception, action and memory tasks, has sparked a long-standing debate on the nature of temporal or…
Noise-induced inhibitory suppression of malfunction neural oscillators
C. J. Tessone, E. Ullner, A. A. Zaikin +2
Motivated by the aim to find new medical strategies to suppress undesirable neural synchronization we study the control of oscillations in a system of inhibitory coupled noisy osci…
