Randomized trial on the effects of a combined physical/cognitive training in aged MCI subjects: the Train the Brain study

Silvestro Micera, Giovanni D'Angelo, Martina Coscia, Marco Mainardi

Age-related cognitive impairment and dementia are an increasing societal burden. Epidemiological studies indicate that lifestyle factors, e.g. physical, cognitive and social activities, correlate with reduced dementia risk; moreover, positive effects on co ...

An in vivo study of the orientation-dependent and independent components of transverse relaxation rates in white matter

Tobias Kober, Tom Hilbert, José Pedro Rebelo Ferreira Marques, Diana Khabipova

Diffusion-weighted imaging (DWI) provides information that allows the estimation of white-matter (WM) fibre orientation and distribution, but it does not provide information about myelin density, fibre concentration or fibre size within each voxel. On the ...

Directional Entropy Based Model For Diffusivity-Driven Tumor Growth

In this work, we present and investigate a multiscale model to simulate 3D growth of glioblastomas (GBMs) that incorporates features of the tumor microenvironment and derives macroscopic growth laws from microscopic tissue structure information. We propose ...

Anatomically-adapted graph wavelets for improved group-level fMRI activation mapping

Dimitri Nestor Alice Van De Ville, Hamid Behjat, Nora Leonardi

A graph based framework for fMRI brain activation mapping is presented. The approach exploits the spectral graphwavelet transform (SGWT) for the purpose of defining an advanced multi-resolutional spatial transformation for fMRI data. The framework extends ...

Red and NIR light dosimetry in the human deep brain

Georges Wagnières, Matthieu Philippe Emmanuel Zellweger, Blaise Lovisa

Photobiomodulation (PBM) appears promising to treat the hallmarks of Parkinson's Disease (PD) in cellular or animal models. We measured light propagation in different areas of PD-relevant deep brain tissue during transcranial, transsphenoidal illumination ...

Structured sparsity through reweighting and application to diffusion MRI

Jean-Philippe Thiran, Yves Wiaux, Alessandro Daducci, Anna Auria Rasclosa

We consider the problem of multiple correlated sparse signals reconstruction and propose a new implementation of structured sparsity through a reweighting scheme. We present a particular application for diffusion Magnetic Resonance Imaging data and show ho ...

Accelerated Microstructure Imaging via Convex Optimisation for regions with multiple fibres (AMICOx)

Jean-Philippe Thiran, Yves Wiaux, Erick Jorge Canales Rodriguez, David Paul Roger Romascano, Alessandro Daducci, Anna Auria Rasclosa

This paper reviews and extends our previous work to enable fast axonal diameter mapping from diffusion MRI data in the presence of multiple fibre populations within a voxel. Most of the existing microstructure imaging techniques use non-linear algorithms t ...

Evaluation of automatic neonatal brain segmentation algorithms: The NeoBrainS12 challenge

Elda Fischi Gomez, Laura Ioana Gui

A number of algorithms for brain segmentation in preterm born infants have been published, but a reliable comparison of their performance is lacking. The NeoBrainS12 study (http://neobrains12.isi.uu.nl), providing three different image sets of preterm born ...
