Influence of physiological noise on accelerated 2D and 3D resting state functional MRI data at 7 T

Rolf Gruetter, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques, Olivier Benoit Thomas Reynaud, João Pedro Forjaco Jorge

Physiological noise often dominates the blood-oxygen level-dependent (BOLD) signal fluctuations in high-field functional MRI (fMRI) data. Therefore, to optimize fMRI protocols, it becomes crucial to investigate how physiological signal fluctuations impact ...

High-Resolution fMRI of Auditory Cortical Map Changes in Unilateral Hearing Loss and Tinnitus

Dimitri Nestor Alice Van De Ville, Wietske Van der Zwaag, Melissa Saenz, Naghmeh Ghazaleh, Stephanie Clarke

Animal models of hearing loss and tinnitus observe pathological neural activity in the tonotopic frequency maps of the primary auditory cortex. Here, we applied ultra high-field fMRI at 7 T to test whether human patients with unilateral hearing loss and ti ...

Upper limb cortical maps in amputees with targeted muscle and sensory reinnervation

Olaf Blanke, Andrea Serino, Wietske Van der Zwaag, Roy Salomon, Giulio Rognini, Roberto Martuzzi, Elisa Canzoneri, Michel Akselrod, Maria Laura Blefari

Neuroprosthetics research in amputee patients aims at developing new prostheses that move and feel like real limbs. Targeted muscle and sensory reinnervation (TMSR) is such an approach and consists of rerouting motor and sensory nerves from the residual li ...

Anatomical and functional properties of the foot and leg representation in areas 3b, 1 and 2 of primary somatosensory cortex in humans: A 7T fMRI study

Olaf Blanke, Wietske Van der Zwaag, Andrea Serino, Roger Gassert, Roberto Martuzzi, Michel Akselrod

Primary somatosensory cortex (S1) processes somatosensory information and is composed of multiple subregions. In particular, tactile information from the skin is encoded in three subregions, namely Brodmann areas (BAs) 3b, 1 and 2, with each area represent ...

Metabolite concentration changes during increase of the BOLD signal in the human visual cortex: a functional magnetic resonance spectroscopy study at 7T

Sustained enhancements in inhibitory control depend primarily on the reinforcement of fronto-basal anatomical connectivity

Wietske Van der Zwaag, Bogdan Draganski, Michaël Mouthon

What are the neurophysiological determinants of sustained supra-normal inhibitory control performance? We addressed this question by coupling multimodal neuroimaging and behavioral investigations of experts in fencing who underwent more than 20,000 h of in ...

Retinotopic encoding of the Ternus-Pikler display reflected in the early visual areas

Michael Herzog, Wietske Van der Zwaag, Gijs Plomp, Yvonne Evelina Thunell

The visual representation of the world is often assumed to be retinotopic, and many visual brain areas are indeed organized retinotopically. Visual perception, however, is not based on a reference frame anchored in retinotopic coordinates. For example, whe ...

Three-dimensional echo planar imaging with controlled aliasing: A sequence for high temporal resolution functional MRI

Rolf Gruetter, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques, Daniel Gallichan, Mayur Narsude

Purpose In this work, we combine three-dimensional echo planar imaging (3D-EPI) with controlled aliasing to substantially increase temporal resolution in whole-brain functional MRI (fMRI) while minimizing geometry-factor (g-factor) losses. Theory and Metho ...

Presurgical brain mapping in epilepsy using simultaneous EEG and functional MRI at ultra-high field: feasibility and first results

Wietske Van der Zwaag, João Pedro Forjaco Jorge, François Lazeyras, Giannina Rita Iannotti

OBJECTIVES: The aim of this study was to demonstrate that eloquent cortex and epileptic-related hemodynamic changes can be safely and reliably detected using simultaneous electroencephalography (EEG)-functional magnetic resonance imaging (fMRI) recordings ...

Recent applications of UHF-MRI in the study of human brain function and structure: a review

Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques

The increased availability of ultra-high-field (UHF) MRI has led to its application in a wide range of neuroimaging studies, which are showing promise in transforming fundamental approaches to human neuroscience. This review presents recent work on structu ...
