  • Brain simulation as a cloud service: the Virtual Brain on EBRAINS
    Schirner, Michael; Domide, Lia; Perdikis, Dionysios; Triebkorn, Paul; Stefanovski, Leon; Pai, Roopa; Prodan, Paula; Valean, Bogdan; Palmer, Jessica; Langford, Chloê; Blickensdörfer, André; Vlag, Michiel van der; Diaz-Pier, Sandra; Peyser, Alexander; Klijn, Wouter; Pleiter, Dirk; Nahm, Anne; Schmid, Oliver; Woodman, Marmaduke; Zehl, Lyuba; Fousek, Jan; Petkoski, Spase; Kusch, Lionel; Hashemi, Meysam; Marinazzo, Daniele; Mangin, Jean-François; Flöel, Agnes; Akintoye, Simisola; Stahl, Bernd Carsten; Cepic, Michael; Johnson, Emily; Deco, Gustavo; McIntosh, Anthony R.; Hilgetag, Claus C.; Morgan, Marc Alard J.; Schuller, Bernd; Upton, Alex; McMurtrie, Colin; Dickscheid, Timo; Bjaalie, Jan G.; Amunts, Katrin; Mersmann, Jochen; Jirsa, Viktor; Ritter, Petra (Elsevier, 2022)
    The Virtual Brain (TVB) is now available as open-source services on the cloud research platform EBRAINS (ebrains.eu). It offers software for constructing, simulating and analysing brain network models including the TVB ...
  • Dynamic functional connectivity reveals altered variability in functional connectivity among patients with major depressive disorder
    Demirtaş, Murat; Tornador Antolin, Cristian, 1979-; Falcón, Carles; López-Solà, Marina; Hernández-Ribas, Rosa; Pujol, Jesús; Menchón, José M.; Ritter, Petra; Cardoner, Narcís; Deco, Gustavo (Wiley, 2016)
    Resting-state fMRI (RS-fMRI) has become a useful tool to investigate the connectivity structure of mental health disorders. In the case of major depressive disorder (MDD), recent studies regarding the RS-fMRI have found ...
  • Dynamic primitives of brain network interaction
    Schirner, Michael; Kong, Xiaolu; Yeo, B.T. Thomas; Deco, Gustavo; Ritter, Petra (Elsevier, 2022)
    What dynamic processes underly functional brain networks? Functional connectivity (FC) and functional connectivity dynamics (FCD) are used to represent the patterns and dynamics of functional brain networks. FC(D) is related ...
  • Estimation of directed effective connectivity from fMRI functional connectivity hints at asymmetries of cortical connectome
    Gilson, Matthieu; Moreno Bote, Rubén; Ponce-Alvarez, Adrián; Ritter, Petra; Deco, Gustavo (Public Library of Science (PLoS), 2016)
    The brain exhibits complex spatio-temporal patterns of activity. This phenomenon is governed by an interplay between the internal neural dynamics of cortical areas and their connectivity. Uncovering this complex relationship ...
  • Inferring multi-scale neural mechanisms with brain network modelling
    Schirner, Michael; Randal McIntosh, Anthony; Jirsa, Viktor K.; Deco, Gustavo; Ritter, Petra (eLife, 2018)
    The neurophysiological processes underlying non-invasive brain activity measurements are incompletely understood. Here, we developed a connectome-based brain network model that integrates individual structural and functional ...
  • Learning how network structure shapes decision-making for bio-inspired computing
    Schirner, Michael; Deco, Gustavo; Ritter, Petra (Nature Research, 2023)
    To better understand how network structure shapes intelligent behavior, we developed a learning algorithm that we used to build personalized brain network models for 650 Human Connectome Project participants. We found that ...
  • Resting state networks in empirical and simulated dynamic functional connectivity
    Glomb, Katharina; Ponce-Alvarez, Adrián; Gilson, Matthieu; Ritter, Petra; Deco, Gustavo (Elsevier, 2017)
    It is well-established that patterns of functional connectivity (FC) - measures of correlated activity between pairs of voxels or regions observed in the human brain using neuroimaging - are robustly expressed in spontaneous ...
  • The dynamics of resting fluctuations in the brain: metastability and its dynamical cortical core
    Deco, Gustavo; Kringelbach, Morten L.; Jirsa, Viktor K.; Ritter, Petra (Nature Publishing Group, 2017)
    In the human brain, spontaneous activity during resting state consists of rapid transitions between functional network states over time but the underlying mechanisms are not understood. We use connectome based computational ...
  • The Dynamics of resting fluctuations in the brain: metastability and its dynamical cortical core
    Deco, Gustavo; Kringelbach, Morten L.; Jirsa, Viktor K.; Ritter, Petra (Nature Research, 2017)
    In the human brain, spontaneous activity during resting state consists of rapid transitions between functional network states over time but the underlying mechanisms are not understood. We use connectome based computational ...
  • The rediscovery of slowness: exploring the timing of cognition
    Kringelbach, Morten L.; McIntosh, Anthony R.; Ritter, Petra; Jirsa, Viktor K.; Deco, Gustavo (Elsevier, 2015)
    Slowness of thought is not necessarily a handicap but could be a signature of optimal brain function. Emerging evidence shows that neuroanatomical and dynamical constraints of the human brain shape its functionality in ...
