    Psychedelic drugs, including lysergic acid diethylamide (LSD) and other agonists of the serotonin 2A receptor (5HT2A-R), induce drastic changes in subjective experience, and provide a unique opportunity to study the ...

    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 ...
  • Galadí, Javier Alejandro; Silva Pereira, Silvana; Sanz Per, Yonatan; Kringelbach, Morten L.; Gayte, Inmaculada; Lauf, Helmut; Tagliazucchi, Enzo; Langa, Jose Antonio; Deco, Gustavo (Elsevier, 2021)
    Brain dynamics depicts an extremely complex energy landscape that changes over time, and its characterisation is a central unsolved problem in neuroscience. We approximate the non-stationary landscape sustained by the human ...

    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 ...
  • Cruzat Grand, Josefina, 1983-; Sanz Perl, Yonatan; Escrichs, Anira; Vohryzek, Jakub; Timmermann, Christopher; Roseman, Leor; Luppi, Andrea I.; Ibañez, Agustin; Nutt, David; Carhart-Harris, Robin L.; Tagliazucchi, Enzo; Deco, Gustavo; Kringelbach, Morten L. (MIT Press, 2022)
    Psychedelic drugs show promise as safe and effective treatments for neuropsychiatric disorders, yet their mechanisms of action are not fully understood. A fundamental hypothesis is that psychedelics work by dose-dependently ...

    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 ...

    Adopting the framework of brain dynamics as a cornerstone of human consciousness, we determined whether dynamic signal coordination provides specific and generalizable patterns pertaining to conscious and unconscious states ...
  • 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 ...
  • Sanz Perl, Yonatan; Fittipaldi, Sol; Gonzalez Campo, Cecilia; Moguilner, Sebastián; Cruzat Grand, Josefina, 1983-; Fraile-Vazquez, Matias E.; Herzog, Rubén; Kringelbach, Morten L.; Deco, Gustavo; Prado, Pavel; Ibañez, Agustin; Tagliazucchi, Enzo (eLife, 2023)
    The treatment of neurodegenerative diseases is hindered by lack of interventions capable of steering multimodal whole-brain dynamics towards patterns indicative of preserved brain health. To address this problem, we combined ...
  • 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 ...

    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 ...

    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 ...
  • Deco, Gustavo; Sanz Perl, Yonatan; Vuust, Peter; Tagliazucchi, Enzo; Kennedy, Henry (Elsevier, 2021)
    What are the key topological features of connectivity critically relevant for generating the dynamics underlying efficient cortical function? A candidate feature that has recently emerged is that the connectivity of the ...
