“…Phenomena that span multiple temporal scales are ubiquitous in brain research ( Breakspear, 2017 ; D’Angelo & Jirsa, 2022 ). For instance, an objective of epilepsy research is to understand the genesis of seizures by analysing the itinerancy of cortical circuitry parameters over seconds to minutes ( Courtiol, Guye, Bartolomei, Petkoski, & Jirsa, 2020 ; Depannemaecker, Destexhe, Jirsa, & Bernard, 2021 ; Depannemaecker, Ezzati, Wang, Jirsa, & Bernard, 2023 ; V. Jirsa et al, 2023 ; V. K. Jirsa, Stacey, Quilichini, Ivanov, & Bernard, 2014 ; Lisi, Rivela, Takai, & Morimoto, 2018 ; Lopez-Sola et al, 2022 ; Ponce-Alvarez et al, 2015 ; R. E. Rosch, Hunter, Baldeweg, Friston, & Meyer, 2018 ). In naturalistic experiments, researchers study the dynamics of the freely-behaving brain in exchange with its environment, on the scale of minutes to hours ( Demirtaş et al, 2019 ; Echeverria-Altuna et al, 2022 ; Lee, Aly, & Baldassano, 2021 ; Meer, Breakspear, Chang, Sonkusare, & Cocchi, 2020 ; Shain, Blank, van Schijndel, Schuler, & Fedorenko, 2020 ).…”
