The dynamic functional connectome: State-of-the-art and perspectives
Dimitri Nestor Alice Van De Ville, Thomas William Arthur Bolton, Maria Giulia Preti
Resting-state functional magnetic resonance imaging (fMRI) has highlighted the rich structure of brain activity in absence of a task or stimulus. A great effort has been dedicated in the last two decades to investigate functional connectivity (FC), i.e. th ...
Elsevier2017Locating Temporal Functional Dynamics of Visual Short-Term Memory Binding using Graph Modular Dirichlet Energy
Pierre Vandergheynst, Benjamin Ricaud, Nauman Shahid, Keith Malcom Smith
Visual short-term memory binding tasks are a promising early marker for Alzheimer's disease (AD). To uncover functional deficits of AD in these tasks it is meaningful to first study unimpaired brain function. Electroencephalogram recordings were obtained f ...

Dimitri Nestor Alice Van De Ville, Stephan Morgenthaler, Thomas William Arthur Bolton, Maria Giulia Preti, Djalel Eddine Meskaldji
Resting-state functional MRI (rs-fMRI) opens a window on large-scale organization of brain function. However, establishing relationships between resting-state brain activity and cognitive or clinical scores is still a difficult task, in particular in terms ...
Elsevier Sci Ltd2016Cognitive markers as potential endophenotypes for schizophrenia
Michael Herzog, Maya Roinishvili
Schizophrenia is a heterogeneous disease strongly influenced by genetic predisposition. A large variety of candidate genes has been identified of which each gene, however, explains only a small proportion of the genetic risk. For this reason, stable marker ...
2016The topology of structural brain connectivity in diseases and spatio-temporal connectomics
The brain is a complex system, composed of multiple neural units interconnected at different spatial and temporal scales. Diffusion MRI allows probing in vivo the anatomical connectivity between different cortical areas through white matter tracts. In para ...
EPFL2015Global tractography with embedded anatomical priors and microstructure information for quantitative connectomics
Over the last decades new technologies have shed the light on an improved understanding of brain structure and function. Recently, an imaging modality referred to as diffusion Magnetic Resonance Imaging (dMRI) has emerged. By exploiting the natural motion ...
EPFL2015An algorithm to predict the connectome of neural microcircuits
Henry Markram, Eilif Benjamin Muller, Srikanth Ramaswamy, Michael Reimann, James Gonzalo King
Experimentally mapping synaptic connections, in terms of the numbers and locations of their synapses and estimating connection probabilities, is still not a tractable task, even for small volumes of tissue. In fact, the six layers of the neocortex contain ...
Frontiers Research Foundation2015Disentangling Dynamic Networks: Separated and Joint Expressions of Functional Connectivity Patterns in Time
Dimitri Nestor Alice Van De Ville, Nora Leonardi
Resting-state functional connectivity (FC) is highly variable across the duration of a scan. Groups of coevolving connections, or reproducible patterns of dynamic FC (dFC), have been revealed in fluctuating FC by applying unsupervised learning techniques. ...
Wiley-Blackwell2014Multi-scale integration and predictability in resting state brain activity
Alessandra Griffa, Patric Hagmann
The human brain displays heterogeneous organization in both structure and function. Here we develop a method to characterize brain regions and networks in terms of information-theoretic measures. We look at how these measures scale when larger spatial regi ...
2014Dynamic reconfiguration of human brain functional networks through neurofeedback
Dimitri Nestor Alice Van De Ville, Frank Scharnowski, Rotem Roza Kopel
Recent fMRI studies demonstrated that functional connectivity is altered following cognitive tasks (e.g., learning) or due to various neurological disorders. We tested whether real-time fMRI-based neurofeedback can be a tool to voluntarily reconfigure brai ...
