Unconsciousness reconfigures modular brain network dynamics

no code implementations19 Dec 2020 Sofia Morena del Pozo, Helmut Laufs, Vincent Bonhomme, Steven Laureys, Pablo Balenzuela, Enzo Tagliazucchi

The dynamic core hypothesis posits that consciousness is correlated with simultaneously integrated and differentiated assemblies of transiently synchronized brain regions.

Non-equilibrium brain dynamics as a signature of consciousness

no code implementations19 Dec 2020 Yonatan Sanz Perl, Hernan Bocaccio, Ignacio Perez-Ipina, Steven Laureys, Helmut Laufs, Morten Kringelbach, Gustavo Deco, Enzo Tagliazucchi

The cognitive functions of human and non-human primates rely on the dynamic interplay of distributed neural assemblies.

Generative embeddings of brain collective dynamics using variational autoencoders

no code implementations2 Jul 2020 Yonatan Sanz Perl, Hernán Boccacio, Ignacio Pérez-Ipiña, Federico Zamberlán, Helmut Laufs, Morten Kringelbach, Gustavo Deco, Enzo Tagliazucchi

We consider the problem of encoding pairwise correlations between coupled dynamical systems in a low-dimensional latent space based on few distinct observations.

Spatio-temporal Dynamics of Intrinsic Networks in Functional Magnetic Imaging Data Using Recurrent Neural Networks

no code implementations3 Nov 2016 R. Devon Hjelm, Eswar Damaraju, Kyunghyun Cho, Helmut Laufs, Sergey M. Plis, Vince Calhoun

We introduce a novel recurrent neural network (RNN) approach to account for temporal dynamics and dependencies in brain networks observed via functional magnetic resonance imaging (fMRI).
