Entropy production of Multivariate Ornstein-Uhlenbeck processes correlates with consciousness levels in the human brain
Matthieu Gilson, Enzo Tagliazucchi, Rodrigo Cofre
Consciousness is supported by complex patterns of brain activity which are indicative of irreversible non-equilibrium dynamics. While the framework of stochastic thermodynamics has…
Model-based machine learning of critical brain dynamics
Hernan Bocaccio, Enzo Tagliazucchi
Criticality can be exactly demonstrated in certain models of brain activity, yet it remains challenging to identify in empirical data. We trained a fully connected deep neural netw…
Non-equilibrium brain dynamics as a signature of consciousness
Yonatan Sanz Perl, Hernan Bocaccio, Ignacio Perez-Ipina +5
The cognitive functions of human and non-human primates rely on the dynamic interplay of distributed neural assemblies. As such, it seems unlikely that cognition can be supported b…
Unconsciousness reconfigures modular brain network dynamics
Sofia Morena del Pozo, Helmut Laufs, Vincent Bonhomme +3
The dynamic core hypothesis posits that consciousness is correlated with simultaneously integrated and differentiated assemblies of transiently synchronized brain regions. We repre…
Whole-brain models to explore altered states of consciousness from the bottom up
Rodrigo Cofré, Rubén Herzog, Pedro A. M. Mediano +4
The scope of human consciousness includes states departing from what most of us experience as ordinary wakefulness. These altered states of consciousness constitute a prime opportu…
Generative embeddings of brain collective dynamics using variational autoencoders
Yonatan Sanz Perl, Hernán Boccacio, Ignacio Pérez-Ipiña +5
We consider the problem of encoding pairwise correlations between coupled dynamical systems in a low-dimensional latent space based on few distinct observations. We used variationa…
Modeling the relationship between regional activation and functional connectivity during wakefulness and sleep
Ignacio Perez Ipiña, Patricio Donnelly Kehoe, Morten Kringelbach +5
Global brain activity self-organizes into discrete patterns characterized by distinct behavioral observables and modes of information processing. The human thalamocortical system i…
Enhanced repertoire of brain dynamical states during the psychedelic experience
Enzo Tagliazucchi, Robin Carhart-Harris, Robert Leech +2
The study of rapid changes in brain dynamics and functional connectivity (FC) is of increasing interest in neuroimaging. Brain states departing from normal waking consciousness are…
