Brain microstructural and functional MRI: developments and application to a rat model of Alzheimer's disease
Magnetic resonance imaging (MRI) has been a valuable tool in investigating the pathological cascade of Alzheimer's disease (AD) and its progression, which are still open questions. Although some MRI-derived hallmarks in terms of functional connectivity and ...
EPFL2023Functional neuroimaging options for tinnitus
Background: The pathophysiology behind tinnitus is still not well understood. Different imaging methods help in the understanding of the complex relationships that lead to the perception of tinnitus.Objective: Herein, different functional imaging methods t ...
SPRINGER2023Brain's Dynamic Functional Organization with Simultaneous EEG-fMRI Networks
João Pedro Forjaco Jorge, Patricia Figueiredo
The brain's functional networks can be assessed using imaging techniques like functional magnetic resonance imaging (fMRI) and electroencephalography (EEG). Recent studies have suggested a link between the dynamic functional connectivity (dFC) captured by ...
SPRINGER INTERNATIONAL PUBLISHING AG2023Improving Functional Connectome Fingerprinting with Degree-Normalization
Background: Functional connectivity quantifies the statistical dependencies between the activity of brain regions, measured using neuroimaging data such as functional magnetic resonance imaging (fMRI) blood-oxygenation-level dependent time series. The netw ...
MARY ANN LIEBERT, INC2022Exploring MEG brain fingerprints: Evaluation, pitfalls, and interpretations
Dimitri Nestor Alice Van De Ville, Alessandra Griffa, Enrico Amico, Ekansh Sareen, Sélima Zahar
Individual characterization of subjects based on their functional connectome (FC), termed “FC fingerprinting”, has become a highly sought-after goal in contemporary neuroscience research. Recent functional magnetic resonance imaging (fMRI) studies have dem ...
2021The relationship between EEG and fMRI connectomes is reproducible across simultaneous EEG-fMRI studies from 1.5T to 7T
Rolf Gruetter, João Pedro Forjaco Jorge, Arwen Blanche Giraud, François Lazeyras, Giannina Rita Iannotti
Both electroencephalography (EEG) and functional Magnetic Resonance Imaging (fMRI) are non-invasive methods that show complementary aspects of human brain activity. Despite measuring different proxies of brain activity, both the measured blood-oxygenation ...
2021Graph Spectral Analysis Of Voxel-Wise Brain Graphs From Diffusion-Weighted Mri
Dimitri Nestor Alice Van De Ville, Hamid Behjat, Anjali Bagunu Tarun
Non-invasive characterization of brain structure has been made possible by the introduction of magnetic resonance imaging (MRI). Graph modeling of structural connectivity has been useful, but is often limited to defining nodes as regions from a brain atlas ...
IEEE2019Multi-slice passband bSSFP for human and rodent fMRI at ultra-high field
Rolf Gruetter, Ileana Ozana Jelescu, Rodrigo Araujo Fraga Da Silva, Olivier Benoit Thomas Reynaud
Balanced steady-state free precession (bSSFP) can be used as an alternative to gradient-echo (GE) EPI for BOLD functional MRI when image distortions and signal drop-outs are severe such as at ultra-high field. However, 3D-bSSFP acquisitions have distinct d ...
2019Engineering Parallel Transmit/Receive Radio-Frequency Coil Arrays for Human Brain MRI at 7 Tesla
Magnetic resonance imaging is widely used in medical diagnosis to obtain anatomical details of the human body in a non-invasive way. Clinical MR scanners typically operate at a static magnetic field strength (B0) of 1.5T or 3T. However, going to higher fie ...
EPFL2019Graph 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. ...
