Information parity increases on functional brain networks under influence of a psychedelic substance

Journal of Physics Complexity March 1, 2023 Aline Viol, G. M. Viswanathan, Oleksandra Soldatkina et al. 4 citations

Abstract The physical basis of consciousness is one of the most intriguing open questions that contemporary science aims to solve. By approaching the brain as an interactive information system, complex network theory has greatly contributed to understand brain process in different states of mind. We study a non-ordinary state of mind by comparing resting-state functional brain networks of...

Characterizing Complex Networks Using Entropy-Degree Diagrams: Unveiling Changes in Functional Brain Connectivity Induced by Ayahuasca

Entropy January 30, 2019 Aline Viol, Fernanda Palhano-Fontes, Heloisa Onias et al. 37 citations

With the aim of further advancing the understanding of the human brain’s functional connectivity, we propose a network metric which we term the geodesic entropy. This metric quantifies the Shannon entropy of the distance distribution to a specific node from all other nodes. It allows to characterize the influence exerted on a specific node considering statistics of the overall network...

Characterizing complex networks using Entropy-degree diagrams: unveiling changes in functional brain connectivity induced by Ayahuasca

arXiv Preprint Archive September 26, 2018 Aline Viol, Fernanda Palhano-Fontes, Heloisa Onias et al.

Open problems abound in the theory of complex networks, which has found successful application to diverse fields of science. With the aim of further advancing the understanding of the brain's functional connectivity, we propose to evaluate a network metric which we term the geodesic entropy. This entropy, in a way that can be made precise, quantifies the Shannon entropy of the distance...
