Collective excitability in a mesoscopic neuronal model of epileptic activity
(2018-01-12)
Article
Open AccessAt the mesoscopic scale, the brain can be understood as a collection of interacting neuronal oscillators, but the extent to which its sustained activity is due to coupling among brain areas is still unclear. Herewe address ... -
Collective stochastic coherence and synchronizability in weighted scale-free networks
(2014-01-21)
Article
Open AccessCoupling frequently enhances noise-induced coherence and synchronization in interacting nonlinear systems, but it does so separately. In principle collective stochastic coherence and synchronizability are incompatible ... -
Consistency of heterogeneous synchronization patterns in complex weighted networks
(Institute of Physics (IOP), 2017-03-10)
Article
Open AccessSynchronization within the dynamical nodes of a complex network is usually considered homogeneous through all the nodes. Here we show, in contrast, that subsets of interacting oscillators may synchronize in different ways ... -

Cross-frequency transfer in a stochastically driven mesoscopic neuronal model
(2015-02-16)
Article
Open AccessThe brain is known to operate in multiple coexisting frequency bands. Increasing experimental evidence suggests that interactions between those distinct bands play a crucial role in brain processes, but the dynamical ... -
Differentiating resting brain states using ordinal symbolic analysis
(Institute of Physics (IOP), 2018-10-08)
Article
Open AccessSymbolic methods of analysis are valuable tools for investigating complex time-dependent signals. In particular, the ordinal method defines sequences of symbols according to the ordering in which values appear in a time ... -
Dynamics of globally delay-coupled neurons displaying subthreshold oscillations
(2009-08)
Article
Restricted access - publisher's policyWe study an ensemble of neurons that are coupled through their time-delayed collective mean field. The individual neuron is modelled using a Hodgkin–Huxley-type conductance model with parameters chosen such that the uncoupled ... -
Excitation/inhibition patterns in a system of coupled cortical columns
(2014)
Conference report
Restricted access - publisher's policyWe study how excitation and inhibition are distributed mesoscopically in small brain regions, by means of a computational model of coupled cortical columns described by neural mass models. Two cortical columns coupled ... -
Extracranial Estimation of Neural Mass Model Parameters Using the Unscented Kalman Filter
(2018-10-15)
Article
Open AccessData assimilation, defined as the fusion of data with preexisting knowledge, is particularly suited to elucidating underlying phenomena from noisy/insufficient observations. Although this approach has been widely used in ... -
Generation of spatiotemporal colored noise
(American Physical Society, 1992-10-01)
Article
Open AccessWe develop an algorithm to simulate a Gaussian stochastic process that is non-δ-correlated in both space and time coordinates. The colored noise obeys a linear reaction-diffusion Langevin equation with Gaussian white noise. ... -

Information routing driven by background chatter in a signaling network
(2011-12-08)
Article
Open AccessLiving systems are capable of processing multiple sources of information simultaneously. This is true even at the cellular level, where not only coexisting signals stimulate the cell, but also the presence of fluctuating ... -

Mesoscopic Segregation of Excitation and Inhibition in a Brain Network Model
(2015-02-09)
Article
Open AccessNeurons in the brain are known to operate under a careful balance of excitation and inhibition, which maintains neural microcircuits within the proper operational range. How this balance is played out at the mesoscopic ... -

Multi-stability and transient chaotic dynamics in semiconductor lasers with time-delayed optical feedback
(World Scientific Publishing, 2010)
Part of book or chapter of book
Restricted access - publisher's policyWe investigate numerically the chaotic transient dynamics of a semiconductor laser with time-delayed optical feedback. This transient behavior is seen in the low-frequency fluctuations (LFF) regime ocurring when the laser ...
