Free-water imaging of the cholinergic basal forebrain and pedunculopontine nucleus in Parkinson’s disease [PDF]
Background: Free-water imaging can predict and monitor dopamine system degeneration in people with Parkinson’s disease. It can also enhance the sensitivity of traditional diffusion tensor imaging (DTI) metrics for indexing neurodegeneration.

Human brain mapping, 2018 Diffusion tensor imaging (DTI) has often been used to examine white matter (WM) tract abnormalities in depressed subjects, but these studies have yielded inconsistent results, probably, due to gender composition or small sample size. In this study, we applied different analysis pipelines to a relatively large sample of individuals with depression to ...

Beyond Broca and Wernicke: Epilepsy surgery in the language areas
Epileptic Disorders, Volume 28, Issue 3, Page 581-601, June 2026.Abstract Epilepsy surgery in language areas is challenged by the intricacies of presurgical workup and surgical planning. In recent decades, the view of language‐related circuitry has shifted from being localized in a few cortical centers to a distributed, dynamically interconnected system, increasing complexity.

Lifespan Trajectories of Asymmetry in White Matter Tracts
Human Brain Mapping, Volume 47, Issue 8, June 1, 2026.(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 ...

Glymphatic dysfunction in trigeminal neuralgia: A multimodal MRI study
Neurobiology of DiseaseBackground: Trigeminal neuralgia (TN) has traditionally been attributed to peripheral neurovascular compression at the trigeminal nerve root entry zone. Recent evidence, however, suggests central mechanisms may contribute to disease pathogenesis.

Human Brain Mapping, Volume 47, Issue 8, June 1, 2026.Ultra‐high‐gradient diffusion MRI (500 mT/m) enables more accurate in vivo axon diameter mapping, detecting smaller fibers with reduced bias and improved repeatability compared to 300 mT/m and showing promise as a microstructural imaging biomarker for development, aging, and disease. ABSTRACT Pushing the resolution limit of axon diameter mapping in the

Biophysical Diffusion MRI Models Better Identify White Matter Tracts in Edema
TomographyBackground/Objectives: White matter (WM) tract detection is critical in the presurgical planning of tumor resection. However, standard-of-care imaging techniques including T1-weighted, T2-weighted, and Diffusion Tensor Imaging (DTI) often fail to ...

Human Brain Mapping, Volume 47, Issue 8, June 1, 2026.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
