    • Task-driven activity reduces the cortical activity space of the brain: experiment and whole-brain modeling 

      Ponce Álvarez, Adrián Fernando; He, Biyu J; Hagmann, Patrick; Deco, Gustavo (Public Library of Science (PLOS), 2015-08-28)
      Article
      Accés obert
      How a stimulus or a task alters the spontaneous dynamics of the brain remains a fundamental open question in neuroscience. One of the most robust hallmarks of task/stimulus-driven brain dynamics is the decrease of variability ...

    • The emergence of spontaneous and evoked functional connectivity in a large-scale model of the brain 

      Ponce Álvarez, Adrián Fernando; Deco, Gustavo (Elsevier, 2015-02-24)
      Capítol de llibre
      Accés restringit per política de l'editorial
      We show how functional connectivity (FC) emerges in an anatomically constrained large-scale spiking model of the brain. To gain theoretical insights, we approximate the model, using a mean-field technique that leads to a ...

    • The Hopf whole-brain model and its linear approximation 

      Ponce Álvarez, Adrián Fernando; Deco, Gustavo (Springer Nature, 2024-01-31)
      Article
      Accés obert
      Whole-brain models have proven to be useful to understand the emergence of collective activity among neural populations or brain regions. These models combine connectivity matrices, or connectomes, with local node dynamics, ...

    • Using in silico perturbational approach to identify critical areas in schizophrenia 

      Vila Vidal, Manel; Kringelbach, Morten L.; Deco, Gustavo (2023-06-15)
      Article
      Accés restringit per política de l'editorial
      Schizophrenia is a debilitating neuropsychiatric disorder whose underlying correlates remain unclear despite decades of neuroimaging investigation. One contentious topic concerns the role of global signal (GS) fluctuations ...

    • Whole-brain neuronal activity displays crackling noise dynamics 

      Ponce Álvarez, Adrián Fernando; Jouary, Adrien; Privat, Martin; Deco, Gustavo; Sumbre, Germán (2018-12-19)
      Article
      Accés obert
      Previous studies suggest that the brain operates at a critical point in which phases of order and disorder coexist, producing emergent patterned dynamics at all scales and optimizing several brain functions. Here, we ...
