  • Deco, Gustavo; Cruzat Grand, Josefina, 1983-; Cabral, Joana; Tagliazucchi, Enzo; Laufs, Helmut; Logothetis, Nikos K.; Kringelbach, Morten L. (National Academy of Sciences, 2019)
    A fundamental problem in systems neuroscience is how to force a transition from one brain state to another by external driven stimulation in, for example, wakefulness, sleep, coma, or neuropsychiatric diseases. This requires ...
  • Rué-Queralt, Joan; Stevner, Angus; Tagliazucchi, Enzo; Laufs, Helmut; Kringelbach, Morten L.; Deco, Gustavo; Atasoy, Selen (Nature Research, 2021)
    Current state-of-the-art functional magnetic resonance imaging (fMRI) offers remarkable imaging quality and resolution, yet, the intrinsic dimensionality of brain dynamics in different states (wakefulness, light and deep ...
  • Stevner, Angus B. A.; Vidaurre, Diego; Cabral, Joana; Rapuano, Kristina M.; Nielsen, Søren Føns Vind; Tagliazucchi, Enzo; Laufs, Helmut; Vuust, Peter; Deco, Gustavo; Woolrich, Mark W.; van Someren, Eus; Kringelbach, Morten L. (Nature Research, 2019)
    The modern understanding of sleep is based on the classification of sleep into stages defined by their electroencephalography (EEG) signatures, but the underlying brain dynamics remain unclear. Here we aimed to move ...
  • Sanz Perl, Yonatan; Bocaccio, Hernán; Pérez-Ipiña, Ignacio; Zamberlán, Federico; Piccinini, Juan; Laufs, Helmut; Kringelbach, Morten L.; Deco, Gustavo; Tagliazucchi, Enzo (American Physical Society, 2020)
    We consider the problem of encoding pairwise correlations between coupled dynamical systems in a low-dimensional latent space based on few distinct observations. We use variational autoencoders (VAEs) to embed temporal ...
  • Jobst, Beatrice M.; Hindriks, Rikkert; Laufs, Helmut; Tagliazucchi, Enzo; Hahn, Gerald; Ponce-Alvarez, Adrián; Stevner, Angus B. A.; Kringelbach, Morten L.; Deco, Gustavo (Nature Research, 2017)
    Recent research has found that the human sleep cycle is characterised by changes in spatiotemporal patterns of brain activity. Yet, we are still missing a mechanistic explanation of the local neuronal dynamics underlying ...
  • Perez Ipiña, Ignacio; Donnelly Kehoe, Patricio; Kringelbach, Morten L.; Laufs, Helmut; Ibañez, Agustin; Deco, Gustavo; Sanz Perl, Yonatan; Tagliazucchi, Enzo (Elsevier, 2020)
    Global brain states are frequently placed within a unidimensional continuum by correlational studies, ranging from states of deep unconsciousness to ordinary wakefulness. An alternative is their multidimensional and ...
  • Piccinini, Juan; Perez Ipiña, Ignacio; Laufs, Helmut; Kringelbach, Morten L.; Deco, Gustavo; Sanz Perl, Yonatan; Tagliazucchi, Enzo (American Institute of Physics (AIP), 2021)
    An outstanding open problem in neuroscience is to understand how neural systems are capable of producing and sustaining complex spatiotemporal dynamics. Computational models that combine local dynamics with in vivo ...
  • Sanz Perl, Yonatan; Bocaccio, Hernán; Pallavicini, Carla; Pérez-Ipiña, Ignacio; Laureys, Steven; Laufs, Helmut; Kringelbach, Morten L.; Deco, Gustavo; Tagliazucchi, Enzo (American Physical Society, 2021)
    The cognitive functions of human and nonhuman primates rely on the dynamic interplay of distributed neural assemblies. As such, it seems unlikely that cognition can be supported by macroscopic brain dynamics at the proximity ...
  • Deco, Gustavo; Tagliazucchi, Enzo; Laufs, Helmut; Sanjuán, Ana; Kringelbach, Morten L. (Society for Neuroscience, 2017)
    A precise definition of a brain state has proven elusive. Here, we introduce the novel local-global concept of intrinsic ignition characterizing the dynamical complexity of different brain states. Naturally occurring ...
  • Sanz Perl, Yonatan; Pallavicini, Carla; Pérez Ipiña, Ignacio; Demertz, Athena; Bonhomme, Vincent; Martial, Charlotte; Panda, Rajanikant; Annen, Jitka; Ibañez, Agustin; Kringelbach, Morten L.; Deco, Gustavo; Laufs, Helmut; Sitt, Jacobo; Laureys, Steven; Tagliazucchi, Enzo (Public Library of Science (PLoS), 2021)
    Consciousness transiently fades away during deep sleep, more stably under anesthesia, and sometimes permanently due to brain injury. The development of an index to quantify the level of consciousness across these different ...
  • Hahn, Gerald; Zamora-López, Gorka; Uhrig, Lynn; Tagliazucchi, Enzo; Laufs, Helmut; Mantini, Dante; Kringelbach, Morten L.; Jarraya, Béchir; Deco, Gustavo (Elsevier, 2021)
    During the sleep-wake cycle, the brain undergoes profound dynamical changes, which manifest subjectively as transitions between conscious experience and unconsciousness. Yet, neurophysiological signatures that can objectively ...
  • Escrichs, Anira; Sanz Perl, Yonatan; Uribe, Carme; Camara, Estela; Türker, Basak; Pyatigorskaya, Nadya; López-González, Ane; Pallavicini, Carla; Panda, Rajanikant; Annen, Jitka; Gosseries, Olivia; Laureys, Steven; Naccache, Lionel; Sitt, Jacobo; Laufs, Helmut; Tagliazucchi, Enzo; Kringelbach, Morten L.; Deco, Gustavo (Nature Research, 2022)
    Significant advances have been made by identifying the levels of synchrony of the underlying dynamics of a given brain state. This research has demonstrated that non-conscious dynamics tend to be more synchronous than in ...
