Mesoscopic Segregation of Excitation and Inhibition in a Brain Network Model
Malagarriga Guasch, Daniel; Villa, Alessandro; García Ojalvo, Jordi; Pons Rivero, Antonio Javier (2015-02-09)
Article
Accés obertNeurons 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 ... -
Modelos físicos de actividad cerebral: de la micro- a la macro-escala
Pons Rivero, Antonio Javier; García Ojalvo, Jordi (2012-09-01)
Article
Accés restringit per política de l'editorial -
Noise-induced up/down dynamics in scale-free neuronal networks
Grau Moya, Jordi; Pons Rivero, Antonio Javier; García Ojalvo, Jordi (2012-07-31)
Article
Accés obertCortical neuronal networks are known to exhibit regimes of dynamical activity characterized by periods of elevated firing (up states) separated by silent phases (down states). Here, we show that up/down dynamics may emerge ... -
Parameter and coupling estimation in small networks of Izhikevich's neurons
Aristides, Raul de Palma; Pons Rivero, Antonio Javier; Cerdeira, Hilda; Masoller Alonso, Cristina; Tirabassi, Giulio (2023-04-12)
Article
Accés obertNowadays, experimental techniques allow scientists to have access to large amounts of data. In order to obtain reliable information from the complex systems that produce these data, appropriate analysis tools are needed. ... -
Quantifying sudden changes in dynamical systems using symbolic networks
Masoller Alonso, Cristina; Hong, Yanhua; Ayad, Sarah; Gustave, Francois; Barland, Stéphane; Pons Rivero, Antonio Javier; Gómez, Sergio; Arenas, Alex (2015-02-24)
Article
Accés obertWe characterize the evolution of a dynamical system by combining two well-known complex systems' tools, namely, symbolic ordinal analysis and networks. From the ordinal representation of a time series we construct a network ... -
Relating structural and functional anomalous connectivity in the aging brain via neural mass modeling
Pons Rivero, Antonio Javier; Cantero, Jose Luis; Atienza, Mercedes; García Ojalvo, Jordi (2010-09)
Article
Accés restringit per política de l'editorialThe structural changes that arise as the brain ages influence its functionality. In many cases, the anatomical degradation simply leads to normal aging. In others, the neurodegeneration is large enough to cause neurological ... -
Relaxation dynamics and frequency response of a noisy cell signaling network
Rue Queralt, Pau; Pons Rivero, Antonio Javier; Domedel Puig, Núria; García Ojalvo, Jordi (2010-12-30)
Article
Accés obertWe investigate the dynamics of cell signaling using an experimentally based Boolean model of the human fibroblast signal transduction network. We determine via systematic numerical simulations the relaxation dynamics of ... -
Stimulus induced resonance in a neural mass model driven with a temporally correlated noise
Jedynak, Maciej; Pons Rivero, Antonio Javier; García Ojalvo, Jordi (2015)
Comunicació de congrés
Accés obert -
Synchronization-based computation through networks of coupled oscillators
Malagarriga Guasch, Daniel; Garcia Vellisca, Mariano A.; Villa, Alessandro; Martín Buldú, Javier; García Ojalvo, Jordi; Pons Rivero, Antonio Javier (2015-08-04)
Article
Accés obertThe mesoscopic activity of the brain is strongly dynamical, while at the same time exhibits remarkable computational capabilities. In order to examine how these two features coexist, here we show that the patterns of ... -
Temporally correlated fluctuations drive epileptiform dynamics
Jedynak, Maciej; Pons Rivero, Antonio Javier; García Ojalvo, Jordi; Goodfellow, Marc (2017-02-01)
Article
Accés obertMacroscopic models of brain networks typically incorporate assumptions regarding the characteristics of afferent noise, which is used to represent input from distal brain regions or ongoing fluctuations in non-modelled ...
