Graph Slepians To Strike A Balance Between Local And Global Network Interactions: Application To Functional Brain Imaging
Dimitri Nestor Alice Van De Ville, Thomas William Arthur Bolton, Younes Farouj, Silvia Obertino
Brain function exhibits coordinated activity patterns that are also reflected in anatomy, a finding that can be harnessed to constrain the dynamics of functional time series to the underlying structure while performing various signal processing operations. ...
IEEE2018Transient networks of spatio-temporal connectivity map communication pathways in brain functional systems
Jean-Philippe Thiran, Pierre Vandergheynst, Alessandra Griffa, Kirell Maël Benzi, Patric Hagmann, Alessandro Daducci, Xavier Bresson, Benjamin Ricaud
The study of brain dynamics enables us to characterize the time-varying functional connectivity among distinct neural groups. However, current methods suffer from the absence of structural connectivity information. We propose to integrate infra-slow neural ...
Elsevier2017Towards tailoring non-invasive brain stimulation using real-time fMRI and Bayesian optimization
Non-invasive brain stimulation, such as transcranial alternating current stimulation (tACS) provides a powerful tool to directly modulate brain oscillations that mediate complex cognitive processes. While the body of evidence about the effect of tACS on be ...
Ieee2016Automated point-neuron simplification of data-driven microcircuit models
Wulfram Gerstner, Henry Markram, Eilif Benjamin Muller, Srikanth Ramaswamy, Michael Reimann, James Gonzalo King, Idan Segev, Marc-Oliver Gewaltig, Christian Antonio Pozzorini, Giuseppe Chindemi, Willem Anna Mark Wybo, Taylor Howard Newton, Christian Andreas Rössert, Max Christian Nolte
A method is presented for the reduction of morphologically detailed microcircuit models to a point-neuron representation without human intervention. The simplification occurs in a modular workflow, in the neighborhood of a user specified network activity s ...
2016The electrophysiological effects of the serotonin 1A receptor agonist buspirone in emotional face processing
Emotional face processing is critically modulated by the serotonergic system, and serotonin (5-HT) receptor agonists impair emotional face processing. However, the specific contribution of the 5-HT1A receptor remains poorly understood. Here we investigated ...
Elsevier Science Bv2015Implementation of a parallel finite-element library: test case on a non-local continuum damage model
Jean-François Molinari, Nicolas Richart
This paper presents an efficient method to implement a damage law within an explicit time-integration scheme, in an open-source object-oriented finite-element framework. The hybrid object/vector design of the framework and implementation choices are detail ...
Elsevier Science Bv2015Anatomically-adapted graph wavelets for improved group-level fMRI activation mapping
Dimitri Nestor Alice Van De Ville, Hamid Behjat, Nora Leonardi
A graph based framework for fMRI brain activation mapping is presented. The approach exploits the spectral graphwavelet transform (SGWT) for the purpose of defining an advanced multi-resolutional spatial transformation for fMRI data. The framework extends ...
Elsevier2015The Cognitive And Neural Time Course Of Empathy And Sympathy: An Electrical Neuroimaging Study On Self-Other Interaction
Although extensively investigated in sociocognitive neuroscience, empathy is difficult to study. The first difficulty originates in its multifaceted nature. According to the multidimensional model, empathy combines emotional, automatic (simulation), cognit ...
Pergamon-Elsevier Science Ltd2014Determination of Inner and Outer Bounds of Reachable Sets Through Subpavings
Francisco Fernandes Castro Rego
The computation of the reachable set of states of a given dynamic system is an important step to verify its safety during operation. There are different methods of computing reachable sets, namely interval integration, capture basin, methods involving the ...
2014Spatiotemporal Brain Dynamics of Emotional Face Processing Modulations Induced by the Serotonin 1A/2A Receptor Agonist Psilocybin
Emotional face processing is critically modulated by the serotonergic system. For instance, emotional face processing is impaired by acute psilocybin administration, a serotonin (5-HT) 1A and 2A receptor agonist. However, the spatiotemporal brain mechanism ...
