Enlargement of the Nerve Fibers of Silenced Lumbosacral Motoneurons in Cats
Biomedicines, 2022 Whether neuromuscular activity influences the size of motor nerves is controversial. All neuromuscular activity in cat hindlimbs was eliminated by spinal cord isolation (SCI), namely, spinal cord transection above and below the medial gastrocnemius (MG ...

Why do axons differ in caliber? [PDF]
, 2012 CNS axons differ in diameter (d) by nearly 100-fold (∼0.1-10 μm); therefore, they differ in cross-sectional area (d(2)) and volume by nearly 10,000-fold.

Biallelic Nonsense Variants in NEFL May Cause a Non-Length-Dependent Neuropathy With Temporal Dispersion on Nerve Conduction Studies. [PDF]
J Peripher Nerv SystABSTRACT Background and Aims Pathogenic variants in NEFL, the gene that encodes the light polypeptide subunit of neurofilaments, are an uncommon cause of autosomal recessive Charcot‐Marie‐Tooth (CMT) disease. In this study, we describe the clinical and electrophysiological features of two families with early‐onset CMT carrying nonsense variants in the ...

Clues from Crouzon: Insights into the potential role of growth factors in the pathogenesis of myelinated retinal nerve fibers. [PDF]
, 2016 PurposeWe present a case of bilateral extensive peripapillary myelinated retinal nerve fibers (MRNF) in an individual with Crouzon syndrome, an inherited form of craniosynostosis caused by overactivation of fibroblast growth factor receptor 2.
