Corticospinal Subfiber Neurite Density Index Detects Upper Motor Neuron Degeneration in Prediagnostic Patients With Sporadic Amyotrophic Lateral Sclerosis

European Journal of Neurology, Volume 33, Issue 7, July 2026.
CST subfiber NDI values were reduced in prediagnostic ALS patients before clinically evident typical upper motor neuron signs emerged. Combining serum NfL with CST subfiber NODDI metrics showed higher diagnostic performance than single markers for differentiating prediagnostic ALS from healthy and ALS‐mimic controls.

Architecture of lower leg muscles in children: Reference curves and potential mechanisms of growth

Journal of Anatomy, Volume 249, Issue 1, Page 54-67, July 2026.
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 ...

Elucidation of Architectural and Compositional Factors Associated With Inter‐Individual Variability in Passive Shear Modulus of the Human Vastus Lateralis in Young Healthy Males

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 7, July 2026.
ABSTRACT Human skeletal muscle exhibits substantial inter‐individual heterogeneity in passive mechanical properties; however, the mechanistic basis underlying this variability remains poorly understood. We aimed to comprehensively examine how compositional and architectural factors are associated with individual variability in passive shear modulus of ...

Epileptic brain network mechanisms and neuroimaging techniques for the brain network

Neural Regeneration Research
Epilepsy can be defined as a dysfunction of the brain network, and each type of epilepsy involves different brain-network changes that are implicated differently in the control and propagation of interictal or ictal discharges.
