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…
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…
A combinatorial framework to quantify peak/pit asymmetries in complex dynamics
Uri Hasson, Jacopo Iacovacci, Ben Davis +4
We explore a combinatorial framework which efficiently quantifies the asymmetries between minima and maxima in local fluctuations of time series. We firstly showcase its performanc…
Large-scale signatures of unconsciousness are consistent with a departure from critical dynamics
Enzo Tagliazucchi, Dante R. Chialvo, Michael Siniatchkin +5
Loss of cortical integration and changes in the dynamics of electrophysiological brain signals characterize the transition from wakefulness towards unconsciousness. The common mech…
A few points suffice: Efficient large-scale computation of brain voxel-wise functional connectomes from a sparse spatio-temporal point-process
Enzo Tagliazucchi, Helmut Laufs, Dante R. Chialvo
Large efforts are currently under way to systematically map functional connectivity between all pairs of millimeter-scale brain regions using big volumes of neuroimaging data. Func…
Electrophysiological correlates of non-stationary BOLD functional connectivity fluctuations
Enzo Tagliazucchi, Frederic von Wegner, Astrid Morzelewski +2
Spontaneous fluctuations of the BOLD (Blood Oxygen Level-Dependent) signal, measured with fMRI (functional Magnetic Resonance Imaging), display a rich and neurobiologically relevan…
