Longitudinal structural connectomic and rich-club analysis in adolescent mTBI reveals persistent, distributed brain alterations acutely through to one year post-injury

Ai Wern Chung, Rebekah Mannix, Henry A. Feldman, P. Ellen Grant, Kiho Im

This increased structural integrity of the local subnetwork may be to compensate for an injured network, or it may be robust to mTBI and is exhibiting a normal developmental trend.  ...  To capture the distributed nature of mTBI and recovery, we employ connectomes to probe the brain's structural organisation.  ...  Acknowledgements The authors wish to thank the families that participated and our colleagues at Boston Children's Hospital for their help.  ...

Enforcing necessary non-negativity constraints for common diffusion MRI models using sum of squares programming

Tom Dela Haije, Evren Özarslan, Aasa Feragen

In this work we investigate the use of sum of squares constraints for various diffusion-weighted MRI models, with a goal of enforcing strict, global non-negativity of the diffusion propagator.  ...  We formulate such constraints for the mean apparent propagator model and for spherical deconvolution, guaranteeing strict non-negativity of the corresponding diffusion propagators.  ...  In this paper we will derive a set of basic mathematical constraints for diffusion-weighted MRI (Section 2).  ...

We present examples of how human brain imaging data is being modeled with network analysis and underscore potential pitfalls.  ...  Here, we review the emerging discipline of network neuroscience, which uses and develops tools from graph theory to better understand and manipulate neural systems, from micro- to macroscales.  ...  We thank Chad Giusti, Jason Kim, and Matthew Hemphill for helpful comments on an earlier version of this manuscript. DSB would also like to acknowledge support from the John D. and Catherine T.  ...
