Entropy production of Multivariate Ornstein-Uhlenbeck processes correlates with consciousness levels in the human brain

arXiv Preprint Archive July 11, 2022 Matthieu Gilson, Enzo Tagliazucchi, Rodrigo Cofré preprint

Consciousness is supported by complex patterns of brain activity which are indicative of irreversible non-equilibrium dynamics. While the framework of stochastic thermodynamics has facilitated the understanding of physical systems of this kind, its application to infer the level of consciousness from empirical data remains elusive. We faced this challenge by calculating entropy production in a...

Meditation-induced effects on whole-brain structural and effective connectivity

Brain Structure and Function May 6, 2022 Eleonora de Filippi, Anira Escrichs, Estela Càmara et al. 23 citations

In the past decades, there has been a growing scientific interest in characterizing neural correlates of meditation training. Nonetheless, the mechanisms underlying meditation remain elusive. In the present work, we investigated meditation-related changes in functional dynamics and structural connectivity (SC). For this purpose, we scanned experienced meditators and control (naive) subjects...
