Transient brain activity disentangles fMRI resting-state dynamics in terms of spatially and temporally overlapping networks

Dimitri Nestor Alice Van De Ville, Fikret Isik Karahanoglu

Dynamics of resting-state functional magnetic resonance imaging (fMRI) provide a new window onto the organizational principles of brain function. Using state-of-the-art signal processing techniques, we extract innovation-driven co-activation patterns (iCAP ...

Optimal Glass-Forming Solvent Brings Sublimation Dynamic Nuclear Polarization to 129Xe Hyperpolarization Biomedical Imaging Standards

Christophe Roussel, Andrea Capozzi, Jean-Noël Hyacinthe, Arnaud Comment

In addition to the dedicated spin exchange optical pumping (SEOP) technique, an alternative method to produce hyperpolarized xenon gas using dynamic nuclear polarization (DNP) followed by a sublimation procedure was proposed. The challenge associated with ...

Improving tumor heterogeneity MRI assessment with histograms

Nathalie Just

By definition, tumours are heterogeneous. They are defined by marked differences in cells, microenvironmental factors (oxygenation levels, pH, VEGF, VPF and TGF-α) metabolism, vasculature, structure and function that in turn translate into heterogeneous dr ...

Superior GRAPPA reconstruction with reduced g-factor noise using 2D CAIPIRINHA for 3D EPI

Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Daniel Gallichan, Mayur Narsude

Efficient GRAPPA or SENSE reconstruction is largely dependent on coil geometry in the direction in which phase encoding steps reduction is performed during partially parallel acquisition. In this study we demonstrate the ability to perform a 2D CAIPIRINHA ...

Digit somatotopy in the human cerebellum: A 7T fMRI study

Rolf Gruetter, Olaf Blanke, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques, Roberto Martuzzi, Remy Kusters

The representation of the human body in the human cerebellum is still relatively unknown, compared to the well-studied homunculus in the primary somatosensory cortex. The investigation of the body representation in the cerebellum and its somatotopic organi ...

Acute Caffeine Administration Impact On Working Memory-Related Brain Activation And Functional Connectivity In The Elderly: A Bold And Perfusion Mri Study

Dimitri Nestor Alice Van De Ville, David Moser

In young individuals, caffeine-mediated blockade of adenosine receptors and vasoconstriction has direct repercussions on task-related activations, changes in functional connectivity, as well as global vascular effects. To date, no study has explored the ef ...

Real-time automated spectral assessment of the BOLD response for neurofeedback at 3 and 7 T

Frank Scharnowski, Yury Koush

Echo-planar imaging is the dominant functional MRI data acquisition scheme for evaluating the BOLD signal. To date, it remains the only approach providing neurofeedback from spatially localized brain activity. Real-time functional single-voxel proton spect ...

Total activation: fMRI deconvolution through spatio-temporal regularization

Dimitri Nestor Alice Van De Ville, Fikret Isik Karahanoglu, François Lazeyras

Confirmatory approaches to fMRI data analysis look for evidence for the presence of pre-defined regressors modeling contributions to the voxel time series, including the BOLD response following neuronal activation. As more complicated questions arise about ...

A 7 tesla FMRI study of amygdala responses to fearful faces

Wietske Van der Zwaag, Nouchine Hadjikhani, Nicole Regula Zürcher Wimmer

The amygdalae are involved in the perception of emotions such as happiness, anger and fear. Because of their proximity to the sinuses, the image signal intensity in T2* weighted fMRI data is often affected by signal loss due to through-slice dephasing, esp ...
