  • Collective excitability in a mesoscopic neuronal model of epileptic activity 

    Jedynak, Maciej; Pons Rivero, Antonio Javier; García Ojalvo, Jordi (2018-01-12)
    Article
    Open Access
    At 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 ...
  • Cross-frequency transfer in a stochastically driven mesoscopic neuronal model 

    Jedynak, Maciej; Pons Rivero, Antonio Javier; García Ojalvo, Jordi (2015-02-16)
    Article
    Open Access
    The 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 

    Quintero Quiroz, Carlos Alberto; Montesano Del Campo, Luis; Pons Rivero, Antonio Javier; Torrent Serra, Maria del Carmen; García Ojalvo, Jordi; Masoller Alonso, Cristina (Institute of Physics (IOP), 2018-10-08)
    Article
    Open Access
    Symbolic 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 ...
  • Entropy measures as descriptors to identify apneas in rheoencephalographic signals 

    González Pijuán, Carmen; Jensen, Erik Weber; Gambus, Pedro L.; Vallverdú Ferrer, Montserrat (2019-06-18)
    Article
    Open Access
    Rheoencephalography (REG) is a simple and inexpensive technique that intends to monitor cerebral blood flow (CBF), but its ability to reflect CBF changes has not been extensively proved. Based on the hypothesis that ...
  • G protein-coupled receptor heterodimerization in the brain 

    Borroto Escuela, Dasiel Óscar; Romero Fernandez, Wilber; Garriga Solé, Pere; Ciruela, Francisco; Narvaez, Manuel; Tarakanov, O.V.; Palkovits, Miklós; Agnati, Luigi F.; Fuxe, Kjell (2013)
    Article
    Restricted access - publisher's policy
    G protein-coupled receptors (GPCRs) play critical roles in cellular processes and signaling and have been shown to form heteromers with diverge biochemical and/or pharmacological activities that are different from those ...
  • Large-scale machine learning in cancer and brain research: new applications that will drive future supercomputing systems 

    Stevens, Rick (Barcelona Supercomputing Center, 2016-09-10)
    Conference report
    Open Access
    In this talk I’ll discuss the DOE/NCI cancer research co-design projects that are a key part of the Presidential Moonshot Cancer Initiative and the brain connectome project at the heart of the National Brain Observatory ...
  • 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
    Open Access
    Neurons 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 ...
