Improved statistical evaluation of group differences in connectomes by screening-filtering strategy with application to study maturation of brain connections between childhood and adolescence

Stephan Morgenthaler, Jean-Philippe Thiran, Djalel Eddine Meskaldji, Patric Hagmann, Dimitri Nestor Alice Van De Ville, David Paul Roger Romascano

Detecting local differences between groups of connectomes is a great challenge in neuroimaging, because the large number of tests that have to be performed and the impact on multiplicity correction. Any available information should be exploited to increase ...

Structural Brain Connectivity in School-Age Preterm Infants Provides Evidence for Impaired Networks Relevant for Higher Order Cognitive Skills and Social Cognition

Jean-Philippe Thiran, Djalel Eddine Meskaldji, Patric Hagmann, François Lazeyras, Elda Fischi Gomez

Extreme prematurity and pregnancy conditions leading to intrauterine growth restriction (IUGR) affect thousands of newborns every year and increase their risk for poor higher order cognitive and social skills at school age. However, little is known about t ...

Intrahemispheric cortico-cortical connections of the human auditory cortex

Jean-Philippe Thiran, Patric Hagmann, Stephanie Clarke, Reto Meuli, Alessandra Griffa, Leila Cammoun

The human auditory cortex comprises the supratemporal plane and large parts of the temporal and parietal convexities. We have investigated the relevant intrahemispheric cortico-cortical connections using in vivo DSI tractography combined with landmark-base ...

Resting-brain functional connectivity predicted by analytic measures of network communication

Jean-Philippe Thiran, Patric Hagmann, Alessandra Griffa, Olaf Sporns

6 The complex relationship between structural and functional connectivity, as measured by noninvasive imaging of the human brain, poses many unresolved challenges and open questions. Here, we apply analytic measures of network communication to the structur ...

Robust T1-Weighted Structural Brain Imaging and Morphometry at 7T Using MP2RAGE

Patric Hagmann, François Lazeyras, Gunnar Krüger, Tobias Kober, José Pedro Rebelo Ferreira Marques, Alexis Roche, Kieran O'Brien

Purpose To suppress the noise, by sacrificing some of the signal homogeneity for numerical stability, in uniform T1 weighted (T1w) images obtained with the magnetization prepared 2 rapid gradient echoes sequence (MP2RAGE) and to compare the clinical utilit ...

Multi-scale integration and predictability in resting state brain activity

Patric Hagmann, Alessandra Griffa

The human brain displays heterogeneous organization in both structure and function. Here we develop a method to characterize brain regions and networks in terms of information-theoretic measures. We look at how these measures scale when larger spatial regi ...

Comparing connectomes across subjects and populations at different scales

Stephan Morgenthaler, Jean-Philippe Thiran, Djalel Eddine Meskaldji, Patric Hagmann, Alessandra Griffa, Elda Fischi Gomez

Brain connectivity can be represented by a network that enables the comparison of the different patterns of struc- tural and functional connectivity among individuals. In the literature, two levels ofstatistical analysis have been con- sidered in comparing ...

Resting-State Functional Connectivity Emerges from Structurally and Dynamically Shaped Slow Linear Fluctuations

Patric Hagmann

Brain fluctuations at rest are not random but are structured in spatial patterns of correlated activity across different brain areas. The question of how resting-state functional connectivity (FC) emerges from the brain's anatomical connections has motivat ...

Flow simulation and hemolysis modeling for a blood centrifuge device

Michel Deville, Mark Sawley, Patric Hagmann

A common blood separation technique is to accelerate the sedimentation of blood constituents by centrifugation and then collect these constituents separately. When subjected to conditions of excessive stress, hemolysis can however occur, whereby the membra ...

Structural connectomics in brain diseases

Jean-Philippe Thiran, Patric Hagmann, Philipp Baumann, Alessandra Griffa

Imaging the connectome in vivo has become feasible through the integration of several rapidly developing fields of science and engineering, namely magnetic resonance imaging and in particular diffusion MRI on one side, image processing and network theory o ...

Mapping the human connectome at multiple scales with diffusion spectrum MRI

Jean-Philippe Thiran, Djalel Eddine Meskaldji, Xavier Gigandet, Patric Hagmann, Reto Meuli, Leila Cammoun, Olaf Sporns, Kim Do

The global structural connectivity of the brain, the human connectome, is now accessible at millimeter scale with the use of MRI. In this paper, we describe an approach to map the connectome by constructing normalized whole-brain structural connection matr ...
