Labeled acetate as a marker of astrocytic metabolism

Astrocytes have various important roles in brain physiology. To further elucidate the details of astrocytic functions under normal and pathological states, astrocyte-specific measurements are mandatory. For studying brain energy metabolism, the use of the ...

Human Primary Auditory Cortex Follows the Shape of Heschl's Gyrus

Melissa Saenz, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques, Stephanie Clarke

The primary auditory cortex (PAC) is central to human auditory abilities, yet its location in the brain remains unclear. We measured the two largest tonotopic subfields of PAC (hA1 and hR) using high-resolution functional MRI at 7 T relative to the underly ...

Regional cortical volumes and congenital heart disease: a MRI study in 22q11.2 deletion syndrome

Jean-Philippe Thiran, Meritxell Bach Cuadra, Maude Schneider, Marie Schaer

Children with congenital heart disease (CHD) who survive surgery often present impaired neurodevelopment and qualitative brain anomalies. However, the impact of CHD on total or regional brain volumes only received little attention. We address this question ...

The Roundtable: An Abstract Model of Conversation Dynamics

Massimo Mastrangeli

Is it possible to abstract a formal mechanism originating schisms and governing the size evolution of social conversations? In this work we propose a constructive solution to this problem: an abstract model of a generic N-party turn-taking conversation. Th ...

Smaller Global and Regional Cortical Volume in Combat-Related Posttraumatic Stress Disorder

Marie Schaer

Context Two sets of findings predict smaller cerebral cortical gray matter volume in adult posttraumatic stress disorder (PTSD). Measures of intracranial tissue volume and cerebral tissue volume have been observed to be smaller in adolescents with maltreat ...

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 ...

Markowitz in the brain?

Kerstin Preuschoff

We review recent rain-scanning (fMRI) evidence that activity in certain sub-cortical structures of the human brain correlate with changes in expected reward, as well as with risk. Risk is measured by variance of payoff, as in Markowitz' theory. The brain s ...

Distribution of the monocarboxylate transporter MCT2 in human cerebral cortex: an immunohistochemical study

Pierre Magistretti, Luc Pellerin, Stephanie Clarke

The monocarboxylate transporter MCT2 belongs to a large family of membrane proteins involved in the transport of lactate, pyruvate and ketone bodies. Although its expression in rodent brain has been well documented, the presence of MCT2 in the human brain ...

Fast-Marching Tractography for Connection Matrix (Fast-TraC)

Jean-Philippe Thiran, Reto Meuli, Patric Hagmann, Leila Cammoun, Xavier Gigandet

Although high angular resolution diffusion MRI techniques are able to solve multiple intra-voxel fiber orientations, the usual streamline Diffusion Spectrum Imaging (DSI) tractography algorithms present some limitations in their ability to map complex fibe ...
