    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 ...
  • 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 ...

    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 ...
  • Sanz Perl, Yonatan; Escrichs, Anira; Tagliazucchi, Enzo; Kringelbach, Morten L.; Deco, Gustavo (Public Library of Science (PLoS), 2022)
    Despite decades of research, there is still a lack of understanding of the role and generating mechanisms of the ubiquitous fluctuations and oscillations found in recordings of brain dynamics. Here, we used whole-brain ...

    Healthy brain dynamics can be understood as the emergence of a complex system far from thermodynamic equilibrium. Brain dynamics are temporally irreversible and thus establish a preferred direction in time (i.e., arrow of ...
  • Deco, Gustavo; Liebana Garcia, Samuel; Sanz Perl, Yonatan; Sporns, Olaf; Kringelbach, Morten L. (Nature Research, 2023)
    Fast, efficient information transfer is essential for the brain to ensure survival. As recently shown in functional magnetic resonance imaging with high spatial resolution, turbulence appears to offer a fundamental way to ...
