A neuronal network model of interictal and recurrent ictal activity
Marinho A. Lopes, KyoungEun Lee, Alexander V. Goltsev
We propose a neuronal network model which undergoes a saddle-node bifurcation on an invariant circle as the mechanism of the transition from the interictal to the ictal (seizure) s…
Noise-enhanced nonlinear response and the role of modular structure for signal detection in neuronal networks
M. A. Lopes, K. -E. Lee, A. V. Goltsev +1
We find that sensory noise delivered together with a weak periodic signal not only enhances nonlinear response of neuronal networks, but also improves the synchronization of the re…
Critical phenomena and noise-induced phase transitions in neuronal networks
K. -E. Lee, M. A. Lopes, J. F. F. Mendes +1
We study numerically and analytically first- and second-order phase transitions in neuronal networks stimulated by shot noise (a flow of random spikes bombarding neurons). Using an…
