Default mode network and the timed up and go in MCI: A structural covariance analysis

Alessandra Griffa

Background: The timed up and go (TUG) is a test used to assess mobility in older adults and patients with neurological conditions. This study aims to compare brain gray matter (GM) correlates and structural covariance networks associated with the TUG time ...

Frontal cortical thickness correlates positively with impulsivity in early psychosis male patients

Alessandra Griffa

Aim Impulsive behaviours, which are frequent in young people suffering from psychosis have been linked to risky and violent behaviours and participate to the burden of psychotic illness. Given that morphological brain correlates of impulsivity in schizophr ...

Methanol Poisoning as an Acute Toxicological Basal Ganglia Lesion Model: Evidence from Brain Volumetry and Cognition

Tobias Kober, Bénédicte Marie Maréchal

Background Acute methanol poisoning leads to optic neuropathy and necrotic lesions of basal ganglia (BG) and subcortical white matter. Survivors of methanol poisoning exhibit long-term executive and memory deficits. Associations between brain volumetry par ...

Nutritional Ketosis Increases NAD+/NADH Ratio in Healthy Human Brain: An in Vivo Study by 31P-MRS

Rolf Gruetter, Lijing Xin, Özlem Ipek, Nicolas Christinat, Maya Shevlyakova

Ketones represent an important alternative fuel for the brain under glucose hypo-metabolic conditions induced by neurological diseases or aging, however their metabolic consequences in healthy brains remain unclear. Here we report that ketones can increase ...

Social isolation stress and chronic glutathione deficiency have a common effect on the glutamine-to-glutamate ratio and myo-inositol concentration in the mouse frontal cortex

João Miguel das Neves Duarte, Rolf Gruetter, Alberto Corcoba

Environmental stress can interact with genetic predisposition to increase the risk of developing psychopathology. In this work, we tested the hypothesis that social isolation stress interacts with impaired glutathione synthesis and have cumulative effects ...

Whole genome grey and white matter DNA methylation profiles in dorsolateral prefrontal cortex

Johannes Gräff, Jose Vicente Sanchez Mut

The brain's neocortex is anatomically organized into grey and white matter, which are mainly composed by neuronal and glial cells, respectively. The neocortex can be further divided in different Brodmann areas according to their cytoarchitectural organizat ...

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

Wietske Van der Zwaag

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 ...

An evaluation of volume-based morphometry for prediction of mild cognitive impairment and Alzheimer's disease

Reto Meuli, Meritxell Bach Cuadra, Alessandro Daducci, Gunnar Krüger, Cristina Granziera, Bénédicte Marie Maréchal, Daniel Andreas Schmitter, Alexis Roche, Delphine Ribes Lemay

Voxel-based morphometry from conventional T1-weighted images has proved effective to quantify Alzheimer’s disease (AD) related brain atrophy and to enable fairly accurate automated classification of AD patients, mild cognitive impaired patients (MCI) and e ...

Brain Correlates of Lane Changing Reaction Time in Simulated Driving

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Huaijian Zhang, Lucian Andrei Gheorghe

Psychophysical studies have reported correlation between neural activity in frontal and parietal areas and subject's reaction time in simple tasks. Here we study whether similar correlates can also be identified in driver's electroencephalography (EEG) act ...

Volume-based vs. voxel-based brain morphometry in Alzheimer's disease prediction

Meritxell Bach Cuadra, Alessandro Daducci, Reto Meuli, Gunnar Krüger, Bénédicte Marie Maréchal, Cristina Granziera, Alexis Roche, Delphine Ribes Lemay, Daniel Andreas Schmitter

Voxel-based morphometry from conventional T1-weighted images has proved effective to quantify Alzheimer's disease (AD) related brain atrophy and to enable accurate automated classification of AD patients, mild cognitive impaired (MCI) patients and elderly ...

The In-Silico Neocortical Microcircuit : From Structure to Dynamics

Michael Reimann

The neocortex is one of the most important brain regions, occupying more than 80% of the brain volume in mammals and contributing massively to its capability of perceiving and interpreting then environment. While it has been extensively studied, it is stil ...

Proton T(1) relaxation times of metabolites in human occipital white and gray matter at 7 T

Rolf Gruetter, Lijing Xin, Benoît Schaller, Huanxiang Lu

Proton T(1) relaxation times of metabolites in the human brain have not previously been published at 7 T. In this study, T(1) values of CH(3) and CH(2) group of N-acetylaspartate and total creatine as well as nine other brain metabolites were measured in o ...

How to Measure Cortical Folding from MR Images: a Step-by-Step Tutorial to Compute Local Gyrification Index

Jean-Philippe Thiran, Meritxell Bach Cuadra, Marie Schaer

Cortical folding (gyrification) is determined during the first months of life, so that adverse events occurring during this period leave traces that will be identifiable at any age. As recently reviewed by Mangin and colleagues2, several methods exist to q ...
