The effects of physiologically plausible connectivity structure on local and global dynamics in large scale brain models

Patric Hagmann, Pascal Hagmann

Functionally relevant large scale brain dynamics operates within the framework imposed by anatomical connectivity and time delays due to finite transmission speeds. To gain insight on the reliability and comparability of large scale brain network simulatio ...

A brief exposure to rightward prismatic adaptation changes resting-state network characteristics of the ventral attentional system

Patric Hagmann, Stephanie Clarke

A brief session of rightward prismatic adaptation (R-PA) has been shown to alleviate neglect symptoms in patients with right hemispheric damage, very likely by switching hemispheric dominance of the ventral attentional network (VAN) from the right to the l ...

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, Patric Hagmann, François Lazeyras, Djalel Eddine Meskaldji, 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 ...

Mapping the Structural Core of Human Cerebral Cortex

Reto Meuli, Patric Hagmann, Leila Cammoun, Xavier Gigandet, Leila Faiza Ben Hamida Cammoun, Pascal Hagmann

Structurally segregated and functionally specialized regions of the human cerebral cortex are interconnected by a dense network of cortico-cortical axonal pathways. Using diffusion spectrum imaging we noninvasively map these pathways within and across cort ...

The Connectome Viewer Toolkit: an open source framework to manage, analyze, and visualize connectomes

Jean-Philippe Thiran, Reto Meuli, Patric Hagmann, Alessandro Daducci, Alia Lemkaddem

Advanced neuroinformatics tools are required for methods of connectome mapping, analysis, and visualization. The inherent multi-modality of connectome datasets poses new challenges for data organization, integration, and sharing. We have designed and imple ...

Understanding Diffusion MR Imaging Techniques: From Scalar Diffusion-weighted Imaging to Diffusion Tensor Imaging and Beyond

Jean-Philippe Thiran, Reto Meuli, Patric Hagmann, Lisa Jonasson

The complex structural organization of the white matter of the brain can be depicted in vivo in great detail with advanced diffusion magnetic resonance (MR) imaging schemes. Diffusion MR imaging techniques are increasingly varied, from the simplest and mos ...

Diffusion MR Image Segmentation: Towards Global Brain Connectivity Analysis

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

The exploration of the human connectome, a term denoting the global structural connectivity of the brain, is accessible to MRI at millimeter and centimeter scales. In this paper, we propose a methodology to map the connectome by constructing normalized who ...

SWISSMETRO - Polarized Linear Motor Combined With Levitation Actuators

Patric Hagmann, Marcel Jufer

SWISSMETRO is a MAGLEV Project, designed for a speed up to 500 km/h in two tunnels under partial vacuum. The authors investigate new possibilities to combine the propulsion and levitation. Polarized inductors for the levitation are studied, implying a pola ...

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 ...

The Connectome Mapper: an open-source processing pipeline to map connectomes with MRI

Jean-Philippe Thiran, Patric Hagmann, Alessandro Daducci, Alessandra Griffa, Reto Meuli, Leila Cammoun, Leila Faiza Ben Hamida Cammoun, Alia Lemkaddem, Xavier Gigandet

Researchers working in the field of global connectivity analysis using diffusion magnetic resonance imaging (MRI) can count on a wide selection of software packages for processing their data, with methods ranging from the reconstruction of the local intra- ...

Error and Attack Tolerance of Layered Complex Networks

Patric Hagmann, Patrick Thiran, Maciej Kurant

Many complex systems may be described by not one but a number of complex networks mapped on each other in a multi-layer structure. Because of the interactions and dependencies between these layers, the state of a single layer does not necessarily reflect w ...

On the reproducibility and anatomical correspondence of DSI tractography

Jean-Philippe Thiran, Reto Meuli, Patric Hagmann, Alessandro Daducci, Gunnar Krüger, Leila Cammoun, Cristina Granziera, Xavier Gigandet, Leila Faiza Ben Hamida Cammoun

Diffusion spectrum imaging (DSI) is increasingly explored in clinical research. The quantitative value of the DSI technique, however, has still to be established. In this context, a better understanding of the reproducibility and the anatomical corresponde ...

Estimating the Confidence Level of White Matter Connections Obtained with MRI Tractography

Jean-Philippe Thiran, Patric Hagmann, Reto Meuli, Leila Cammoun, Xavier Gigandet, Leila Faiza Ben Hamida Cammoun, Maciej Kurant

Background Since the emergence of diffusion tensor imaging, a lot of work has been done to better understand the properties of diffusion MRI tractography. However, the validation of the reconstructed fiber connections remains problematic in many respects. ...

Thalamic nuclei clustering on High Angular Resolution Diffusion Images

Jean-Philippe Thiran, Reto Meuli, Patric Hagmann, Leila Cammoun, Leila Faiza Ben Hamida Cammoun, Pascal Hagmann

Thalamic nuclei can be distinguished by their characteristic fiber orientations, which influence the diffusion. Fiber orientations are relatively aligned within a nucleus due to the fact that the cerebrocortical striations within a nucleus all target the s ...
