Architecture of lower leg muscles in children: Reference curves and potential mechanisms of growth
Muscle architecture (physiological cross‐sectional area, fascicle lengths and pennation angle) was measured from multimodal MRI scans of the lower legs of 197 children aged ≤15 years. We showed that lower leg muscle volumes (product of PCSA and fascicle length) increase primarily through increases in PCSA (transverse growth) rather than increases in ...

Nonlinear tube-fitting for the analysis of anatomical and functional structures
We are concerned with the estimation of the exterior surface and interior summaries of tube-shaped anatomical structures. This interest is motivated by two distinct scientific goals, one dealing with the distribution of HIV microbicide in the colon and ...

Abstract INTRODUCTION Locus coeruleus (LC) structural integrity declines early in sporadic and autosomal dominant Alzheimer's disease (AD). We examined LC–entorhinal cortex (LC‐EC) tract integrity and its association with amyloid and tau pathology and memory in autosomal dominant AD (ADAD).

Real-time tractography: computation and visualization
Did you know that even though tractography is often considered a computationally expensive and offline process, the latest algorithms can now be performed in real-time without sacrificing accuracy? Interactive real-time tractography has proven to be valuable in surgical planning and has the potential to enhance neuromodulation therapies, highlighting ...

Abstract Background Previous task‐based fMRI work in a large cohort of young adults identified nine large‐scale functional brain networks whose encoding‐related responsivity was robustly associated with individual differences in episodic memory. It remains unclear whether structural connectivity within these task‐fMRI‐defined networks explains inter ...

Affective and cognitive prefrontal cortex projections to the lateral habenula in humans
Anterior insula (AI) and dACC are known to process information about pain, loss, adversities, bad, harmful or suboptimal choices and consequences that threaten survival or well-being.

Abstract Objective Expanded indications, diagnostic tools, and treatment options have transformed the landscape of modern pediatric epilepsy surgery. Published real‐world experiences from large surgical cohorts are still needed. To close this gap, we evaluated access, indications, treatment, and outcomes in a contemporary pediatric epilepsy surgery ...

Lifespan Trajectories of Asymmetry in White Matter Tracts
(A) Large‐scale lifespan modeling of white matter asymmetry. Diffusion MRI data from 35,000+ individuals (0‐100 years) across 50 cohorts were used to generate normative lifespan trajectories of white matter asymmetry. Thirty bilateral tracts were segmented, and microstructural (FA, MD, AD, RD) and macrostructural (volume, length) features were ...

Sensorimotor mu‐rhythm phase modulates corticospinal excitability; however, the influence of mu‐phase varies across individuals and could be related to microstructural connectivity between primary somatosensory (S1) and motor (M1) cortices. Our findings suggest that higher S1–M1 microstructural connectivity is associated with a stronger mu‐phase effect
