Macroscopic properties, such as temperature, may have no meaning at the microscopic level, but they arise as emergent properties in statistical mechanics when the number of particles becomes sufficiently large. The success of statistical mechanics in explaining and predicting a variety of macroscopic phenomena has motivated the application of concepts and methods of statistical physics to study complex systems and complex networks, including in neuroscience. Our aim here is to apply this approach to a key problem in neuroscience: how can we quantitatively understand the neural correlates of altered mental states induced by psychedelic substances? We first give an overview of basic concepts concerning functional connectivity of brain regions. We then discuss the phenomenology and the neuroscience related to psychedelics. Finally, we review some studies that have applied statistical physics and the theory of complex networks to try to gain a better understanding of the brain under the influence of psychedelicsArticle O mundo dos sonhos pós-covid(2020-08-26) Ribeiro, Sidarta Tollendal Gomes; Araújo, Dráulio Barros de; Barros Filho, Allan Kardec DuailibeArticle Unveiling ayahuasca psychopharmacology: the accomplishments of Jordi Riba (1968-2020)(2020-10) Santos, Rafael G. dos; Araújo, Dráulio Barros de; Sanches, Rafael F; Hallak, Jaime E.Article The dream of God: how do religion and science see lucid dreaming and other conscious states during sleep?(Frontiers Media SA, 2020-10) Rolim, Sérgio Arthuro Mota; Bulkeley, Kelly; Esmaile, Stephany Campanelli; Soares, Bruno Lobão; Araújo, Dráulio Barros de; Ribeiro, Sidarta Tollendal GomesArticle Effects of yoga respiratory practice (bhastrika pranayama) on anxiety, affect, and brain functional connectivity and activity: a randomized controlled trial(2020-05-21) Novaes, Morgana M.; Palhano-Fontes, Fernanda; Onias, Heloisa; Andrade, Katia C.; Lobão-Soares, Bruno; Arruda-Sanchez, Tiago; Kozasa, Elisa H.; Santaella, Danilo F.; Araújo, Dráulio Barros deArticle Changes in cortisol but not in brain-derived neurotrophic factor modulate the association between sleep disturbances and major depression(2020-04-28) Santiago, Giuliana Travassos Pires; Galvão, Ana Cecília de Menezes; Almeida, Raíssa Nóbrega de; Mota-Rolim, Sergio Arthuro; Palhano-Fontes, Fernanda; Maia-de-Oliveira, João Paulo; Araújo, Dráulio Barros de; Lobão-Soares, Bruno; Galvão-Coelho, Nicole LeiteArticle Subacute effects of the psychedelic ayahuasca on the salience and default mode networks(2020-04-07) Pasquini, Lorenzo; Palhano-Fontes, Fernanda; Araújo, Dráulio Barros deArticle The impact of ayahuasca on suicidality: results from a randomized controlled trial(2019-11-19) Zeifman, Richard J.; Palhano-Fontes, Fernanda; Hallak, Jaime; Arcoverde, Emerson; Maia-Oliveira, João Paulo; Araújo, Dráulio Barros deArticle Is perception the missing link between creativity, curiosity and schizotypy?
