  • The avalanche-like behaviour of large-scale haemodynamic activity from wakefulness to deep sleep 
    Bocaccio, Hernán; Pallavicini, Carla; Castro, Mariana Nair; Sánchez, Stella Maris; De Pino, Gabriela; Laufs, Helmut; Villarreal, Mirta Fabiana; Tagliazucchi, Enzo (Royal Society, 2019-09-11)
    Increasing evidence suggests that responsiveness is associated with critical or near-critical cortical dynamics, which exhibit scale-free cascades of spatio-temporal activity. These cascades, or 'avalanches', have been ...
  • Clasificación de estados cerebrales basada en la identificación automática de fenómenos críticos. 
    Bocaccio, Hernán (2021)
    En esta tesis se estudió el cerebro y sus propiedades emergentes bajo el marco de los sistemas complejos. En este terreno, la emergencia de la consciencia tiene la particularidad de ser uno de los temas más misteriosos y ...
  • Data augmentation based on dynamical systems for the classification of brain states 
    Sanz Perl, Yonatan; Pallavicini, Carla; Perez Ipiña, Ignacio; Kringelbach, Morten; Deco, Gustavo; Laufs, Helmut; Tagliazucchi, Enzo (Elsevier, 2020-07-10)
    The application of machine learning algorithms to neuroimaging data shows great promise for the classification of physiological and pathological brain states. However, classifiers trained on high dimensional data are prone ...
  • Lifetime use of psychedelics is associated with better mental health indicators during the COVID-19 pandemic 
    Cavanna, Federico; Pallavicini, Carla; Milano, Virginia; Cuiule, Juan; Di Tella, Rocco; González, Pablo; Tagliazucchi, Enzo (Akadémiai Kiadó, 2021-05-04)
    Background and aims: The COVID-19 pandemic and its consequences represent a major challenge to the mental health and well-being of the general population. Building on previous work on the potential long-term benefits of ...
  • Low-dimensional organization of global brain states of reduced consciousness 
    Perl, Yonatan Sanz; Pallavicini, Carla; Piccinini, Juan; Demertzi, Athena; Bonhomme, Vincent; Martial, Charlotte; Panda, Rajanikant; Alnagger, Naji; Annen, Jitka; Gosseries, Olivia; Ibañez, Agustín; Laufs, Helmut; Sitt, Jacobo D.; Jirsa, Viktor K.; Kringelbach, Morten; Laureys, Steven; Deco, Gustavo; Tagliazucchi, Enzo (Elsevier, 2023-05-11)
    Brain states are frequently represented using a unidimensional scale measuring the richness of subjective experience (level of consciousness). This description assumes a mapping between the high-dimensional space of ...
  • Meditation Increases the Entropy of Brain Oscillatory Activity 
    Martínez Vivot, Rocío; Pallavicini, Carla; Zamberlan, Federico; Vigo, Daniel Eduardo; Tagliazucchi, Enzo (Elsevier, 2020-04-01)
    We address the hypothesis that the entropy of neural dynamics indexes the intensity and quality of conscious content. Previous work established that serotonergic psychedelics can have a dysregulating effect on brain activity, ...
  • Natural language signatures of psilocybin microdosing 
    Sanz, Camila; Cavanna, Federico; Muller, Stephanie; de la Fuente, Laura A.; Zamberlan, Federico; Palmucci, Matías; Janeckova, Lucie; Kuchar, Martin; Carrillo, Facundo; García, Adolfo M.; Pallavicini, Carla; Tagliazucchi, Enzo (Springer-Verlag, 2022-09)
    Rationale: Serotonergic psychedelics are being studied as novel treatments for mental health disorders and as facilitators of improved well-being, mental function, and creativity. Recent studies have found mixed results ...
  • Neural and subjective effects of inhaled N,N-dimethyltryptamine in natural settings 
    Pallavicini, Carla; Cavanna, Federico; Zamberlan, Federico; de la Fuente, Laura A.; Ilksoy, Yayla; Perl, Yonatan Sanz; Arias, Mauricio; Romero, Celeste; Carhart-Harris, Robin; Timmermann, Christopher; Tagliazucchi, Enzo (Sage, 2021-02-10)
    Background: N,N-dimethyltryptamine is a short-acting psychedelic tryptamine found naturally in many plants and animals. Few studies to date have addressed the neural and psychological effects of N,N-dimethyltryptamine ...
  • Perturbations in dynamical models of whole-brain activity dissociate between the level and stability of consciousness 
    Sanz Perl, Yonatan; Pallavicini, Carla; Pérez Ipiña, Ignacio; Demertzi, Athena; Bonhomme, Vincent; Martial, Charlotte; Panda, Rajanikant; Annen, Jitka; Ibañez, Agustín; Kringelbach, Morten; Deco, Gustavo; Laufs, Helmut; Sitt, Jacobo D.; Laureys, Steven; Tagliazucchi, Enzo (Public Library of Science, 2021-07-27)
    Consciousness transiently fades away during deep sleep, more stably under anesthesia, and sometimes permanently due to brain injury. The development of an index to quantify the level of consciousness across these different ...
  • Relationship among subjective responses, flavor, and chemical composition across more than 800 commercial cannabis varieties 
    de la Fuente, Laura A.; Zamberlan, Federico; Sánchez Ferrán, Andrés; Carrillo, Facundo; Tagliazucchi, Enzo; Pallavicini, Carla (BioMed Central Ltd, 2020-07-17)
    Background: Widespread commercialization of cannabis has led to the introduction of brand names based on users' subjective experience of psychological effects and flavors, but this process has occurred in the absence of ...
  • Spectral signatures of serotonergic psychedelics and glutamatergic dissociatives 
    Pallavicini, Carla; Vilas, Martina G.; Villarreal, Mirta Fabiana; Zamberlan, Federico; Muthukumaraswamy, Suresh; Nutt, David; Carhart-Harris, Robin; Tagliazucchi, Enzo (Elsevier, 2019-06-24)
    Classic serotonergic psychedelics are remarkable for their capacity to induce reversible alterations in consciousness of the self and the surroundings, mediated by agonism at serotonin 5-HT2A receptors. The subjective ...
  • The entropic tongue: Disorganization of natural language under LSD 
    Sanz, Camila; Pallavicini, Carla; Carrillo, Facundo; Zamberlan, Federico; Sigman, Mariano; Mota, Natalia; Copelli, Mauro; Ribeiro, Sidarta; Nutt, David; Carhart-Harris, Robin; Tagliazucchi, Enzo (Academic Press, 2020-12-08)
    Serotonergic psychedelics have been suggested to mirror certain aspects of psychosis, and, more generally, elicit a state of consciousness underpinned by increased entropy of on-going neural activity. We investigated the ...
  • Unifying turbulent dynamics framework distinguishes different brain states 
    Escrichs, Anira; Sanz Perl, Yonatan; Uribe, Carme; Camara, Estela; Türker, Basak; Pyatigorskaya, Nadya; López-González, Ane; Pallavicini, Carla; Panda, Rajanikant; Annen, Jitka; Gosseries, Olivia; Laureys, Steven; Naccache, Lionel; Sitt, Jacobo D.; Laufs, Helmut; Tagliazucchi, Enzo; Kringelbach, Morten; Deco, Gustavo (Nature Publishing Group UK, 2022-05-29)
