Ocular manifestations in Gorlin-Goltz syndrome [PDF]

open access: yes, 2019
Background: Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome, is a rare genetic disorder that is transmitted in an autosomal dominant manner with complete penetrance and variable expressivity.

Diffusion of Ions in Myelinated Nerve Fibers

open access: yesBiophysical Journal, 1979
The diffusion of ions towards or away from the inner side of the nodal membrane in preparations, the cut ends of which are placed in various media, was investigated. The ion concentration changes were calculated by numerical solution of the unidimensional electrodiffusion equation under a variety of media compositions, axoplasmic diffusion coefficients,

Reinnervation of spinal cord anterior horn cells after median nerve repair using transposition with other nerves

open access: yesNeural Regeneration Research, 2019
Our previous studies have confirmed that during nerve transposition repair to injured peripheral nerves, the regenerated nerve fibers of motor neurons in the anterior horn of the spinal cord can effectively repair distal nerve and target muscle tissue ...

Paresthesia thresholds in spinal cord stimulation: a comparison of theoretical results with clinical data [PDF]

open access: yes, 1993
The potential distributions produced in the spinal cord and surrounding tissues by dorsal epidural stimulation at the midcervical, midthoracic, and low thoracic levels were calculated with the use of a volume conductor model.

Why do axons differ in caliber? [PDF]

open access: yes, 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.

Comparison of Morphometric Aspects of Light and Electron Microscopy of the Hypoglossal Nerve between Young and Aged Male Wistar Rats [PDF]

open access: yesCell Journal, 2012
Objective: Age-related changes occur in many different systems of the body. Many elderlypeople show dysphagia and dysphonia. This research was conducted to evaluatequantitatively the morphometrical changes of the hypoglossal nerve resulting from theaging

Mice Hemizygous for a Pathogenic Mitofusin-2 Allele Exhibit Hind Limb/Foot Gait Deficits and Phenotypic Perturbations in Nerve and Muscle. [PDF]

open access: yes, 2016
Charcot-Marie-Tooth disease type 2A (CMT2A), the most common axonal form of hereditary sensory motor neuropathy, is caused by mutations of mitofusin-2 (MFN2). Mitofusin-2 is a GTPase required for fusion of mitochondrial outer membranes, repair of damaged

The alternatively spliced fibronectin CS1 isoform regulates IL-17A levels and mechanical allodynia after peripheral nerve injury. [PDF]

open access: yes, 2015
BackgroundMechanical pain hypersensitivity associated with physical trauma to peripheral nerve depends on T-helper (Th) cells expressing the algesic cytokine, interleukin (IL)-17A.

Simulation of intrafascicular and extraneural nerve stimulation [PDF]

open access: yes, 1988
A model of nerve stimulation for control of muscle contraction and ensuing isometrical muscle force has been developed and implemented in a simulation algorithm.

A distributed-parameter model of the myelinated nerve fiber [PDF]

open access: yesJournal of Theoretical Biology, 1988
This paper presents a new model for the characterization of electrical activity in the nodal, paranodal and internodal regions of isolated amphibian and mammalian myelinated nerve fibers. It differs from previous models in the following ways: (1) in its ability to incorporate detailed anatomical and electrophysiological data; (2) in its approach to the
