The human vestibular cortex revealed by coordinate-based activation likelihood estimation meta-analysis

Olaf Blanke, Fred Mast, Christophe Lopez

The vestibular system contributes to the control of posture and eye movements and is also involved in various cognitive functions including spatial navigation and memory. These functions are subtended by projections to a vestibular cortex, whose exact loca ...

In vivo Structural Imaging of the Cerebellum, the Contribution of Ultra-High Fields

Rolf Gruetter, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques

This review covers some of the contributions to date from cerebellar imaging studies performed at ultra-high magnetic fields. A short overview of the general advantages and drawbacks of the use of such high field systems for imaging is given. One of the bi ...

Diffusion Spectrum Imaging Shows the Structural Basis of Functional Cerebellar Circuits in the Human Cerebellum In Vivo

Reto Meuli, Cristina Granziera, Nouchine Hadjikhani, Van Jay Wedeen

Background: The cerebellum is a complex structure that can be affected by several congenital and acquired diseases leading to alteration of its function and neuronal circuits. Identifying the structural bases of cerebellar neuronal networks in humans in vi ...

On the origin of the MR image phase contrast: An in vivo MR microscopy study of the rat brain at 14.1 T

Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Rajika Maddage

Recent studies at high magnetic fields using the phase of gradient-echo MR images have shown the ability to unveil cortical substructure in the human brain. To investigate the contrast mechanisms in phase imaging, this study extends, for the first time, ph ...

Diffusion spectrum magnetic resonance imaging (DSI) tractography of crossing fibers

Patric Hagmann, Van Jay Wedeen

MRI tractography is the mapping of neural fiber pathways based on diffusion MRI of tissue diffusion anisotropy. Tractography based on diffusion tensor imaging (DTI) cannot directly image multiple fiber orientations within a single voxel. To address this li ...

Synaptic plasticity at the cerebellum input stage: mechanisms and functional implications

The mf-GrC relay provides the case of a synapse at which elementary neurotransmission mechanisms are particularly well understood allowing a precise investigation of synaptic plasticity. An interesting consequence is that a presynaptic mechanism of LTP cou ...

Diffusion Spectrum Imaging Tractography in Complex Cerebral White Matter: An Investigation of the Centrum Semiovale

Jean-Philippe Thiran, Reto Meuli, Patric Hagmann, Van Jay Wedeen

DSI is a novel high angular resolution diffusion MR imaging technique with high b-values that is able to map complex white matter architecture in the brain. We evaluate the capacity of a simple tractography method to define the essential fiber crossing ana ...

MCT2 is a major neuronal monocarboxylate transporter in the adult mouse brain

Pierre Magistretti, Luc Pellerin

Although previous Northern blot and in situ hybridization studies suggested that neurons express the monocarboxylate transporter MCT2, subsequent immunohistochemical analyzes either failed to confirm the presence of this transporter or revealed only a low ...

Study of tricarboxylic acid cycle flux changes in human visual cortex during hemifield visual stimulation using (1)H-[(13)C] MRS and fMRI

Rolf Gruetter

The relationships between brain activity and accompanying hemodynamic and metabolic alterations, particularly between the cerebral metabolic rate of oxygen utilization (CMR(O2)) and cerebral blood flow (CBF), are not thoroughly established. CMR(O2) is clos ...

Automated Segmentation of the Corpus Callosum in Midsagittal Brain Magnetic Resonance Images

Michaël Unser

We propose a new algorithm to find the corpus callosum automatically from midsagittal brain MR (magnetic resonance) images using the statistical characteristics and shape information of the corpus callosum. We first extract regions satisfying the statistic ...
