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, João Pedro Forjaco Jorge, Olivier Benoit Thomas Reynaud
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 ...
Wiley-Blackwell2017Upper limb cortical maps in amputees with targeted muscle and sensory reinnervation
Olaf Blanke, Andrea Serino, Michel Akselrod, Wietske Van der Zwaag, Roy Salomon, Giulio Rognini, Roberto Martuzzi, Elisa Canzoneri, 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 ...
Oxford University Press2017Anatomical 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, Andrea Serino, Michel Akselrod, Wietske Van der Zwaag, Roger Gassert, Roberto Martuzzi
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 ...
2017Retinotopic 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 ...
Association for Research in Vision and Ophthalmology (ARVO)2016Neural Decoding of Discriminative Auditory Object Features Depends on Their Socio-Affective Valence
Melissa Saenz, Wietske Van der Zwaag
Human voices consist of specific patterns of acoustic features that are considerably enhanced during affective vocalizations. These acoustic features are presumably used by listeners to accurately discriminate between acoustically or emotionally similar vo ...
Oxford University Press (OUP)2016Presurgical 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 ...
Springer Verlag2016Recent 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 ...
Wiley-Blackwell2016Three-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 ...
Wiley-Blackwell2016Ballistocardiogram artifact correction taking into account physiological signal preservation in simultaneous EEG-fMRI
Wietske Van der Zwaag, João Pedro Forjaco Jorge, Patricia Figueiredo, Ana Francisca Leal Silva Soares
The ballistocardiogram (BCG) artifact is currently one of the most challenging in the EEG acquired concurrently with fMRI, with correction invariably yielding residual artifacts and/or deterioration of the physiological signals of interest. In this paper, ...
Elsevier2016Physiological noise in human cerebellar fMRI
Rolf Gruetter, Wietske Van der Zwaag, João Pedro Forjaco Jorge, Denis Butticaz
Objectives To compare physiological noise contributions in cerebellar and cerebral regions of interest in high-resolution functional magnetic resonance imaging (fMRI) data acquired at 7T, to estimate the need for physiological noise removal in cerebellar f ...
