The development of an index to quantify the level of consciousness across these different states is regarded as a key problem both in basic and clinical neuroscience. We argue that this problem is ill-defined since such an index would not exhaust all the relevant information about a given state of consciousness. While the level of consciousness can be taken to describe the actual brain state, a complete characterization should also include its potential behavior against external perturbations. We developed and analyzed whole-brain computational models to show that the stability of conscious states provides information complementary to their similarity to conscious wakefulness. Our work leads to a novel methodological framework to sort out different brain states by their stability and reversibility, and illustrates its usefulness to dissociate between physiological (sleep), pathological (brain-injured patients), and pharmacologically-induced (anesthesia) loss of consciousness.<\/jats:p>","DOI":"10.1371\/journal.pcbi.1009139","type":"journal-article","created":{"date-parts":[[2021,7,27]],"date-time":"2021-07-27T13:22:26Z","timestamp":1627392146000},"page":"e1009139","update-policy":"https:\/\/doi.org\/10.1371\/journal.pcbi.corrections_policy","source":"Crossref","is-referenced-by-count":67,"title":["Perturbations in dynamical models of whole-brain activity dissociate between the level and stability of consciousness"],"prefix":"10.1371","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1270-5564","authenticated-orcid":true,"given":"Yonatan","family":"Sanz Perl","sequence":"first","affiliation":[]},{"given":"Carla","family":"Pallavicini","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3073-3526","authenticated-orcid":true,"given":"Ignacio","family":"P\u00e9rez Ipi\u00f1a","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8021-3759","authenticated-orcid":true,"given":"Athena","family":"Demertzi","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6356-547X","authenticated-orcid":true,"given":"Vincent","family":"Bonhomme","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6291-3460","authenticated-orcid":true,"given":"Charlotte","family":"Martial","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0960-4340","authenticated-orcid":true,"given":"Rajanikant","family":"Panda","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7459-4345","authenticated-orcid":true,"given":"Jitka","family":"Annen","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6758-5101","authenticated-orcid":true,"given":"Agustin","family":"Iba\u00f1ez","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3908-6898","authenticated-orcid":true,"given":"Morten","family":"Kringelbach","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8995-7583","authenticated-orcid":true,"given":"Gustavo","family":"Deco","sequence":"additional","affiliation":[]},{"given":"Helmut","family":"Laufs","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3878-4846","authenticated-orcid":true,"given":"Jacobo","family":"Sitt","sequence":"additional","affiliation":[]},{"given":"Steven","family":"Laureys","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0421-9993","authenticated-orcid":true,"given":"Enzo","family":"Tagliazucchi","sequence":"additional","affiliation":[]}],"member":"340","published-online":{"date-parts":[[2021,7,27]]},"reference":[{"issue":"5","key":"pcbi.1009139.ref001","doi-asserted-by":"crossref","first-page":"776","DOI":"10.1016\/j.neuron.2020.01.026","article-title":"Conscious Processing and the Global Neuronal Workspace Hypothesis","volume":"105","author":"G.
