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

Immunomodulation stimulates the innervation of engineered tooth organ [PDF]

open access: yes, 2014
The sensory innervation of the dental mesenchyme is essential for tooth function and protection. Sensory innervation of the dental pulp is mediated by axons originating from the trigeminal ganglia and is strictly regulated in time. Teeth can develop from

Asymptotic construction of pulses in the Hodgkin Huxley model for myelinated nerves [PDF]

open access: yes, 2005
A quantitative description of pulses and wave trains in the spatially discrete Hodgkin-Huxley model for myelinated nerves is given. Predictions of the shape and speed of the waves and the thresholds for propagation failure are obtained.

Analysis of current density and related parameters in spinal cord stimulation [PDF]

open access: yes, 1998
A volume conductor model of the spinal cord and surrounding anatomical structures is used to calculate current (and current density) charge per pulse, and maximum charge density per pulse at the contact surface of the electrode in the dorsal epidural ...

Nerve Preparation and Recordings for Pharmacological Tests of Sensory and Nociceptive Fiber Conduction Ex Vivo

open access: yesBio-Protocol
Measuring signal propagation through nerves is a classical electrophysiological technique established decades ago to evaluate sensory and motor functions in the nervous system.

Sleeve bridging of the rhesus monkey ulnar nerve with muscular branches of the pronator teres: multiple amplification of axonal regeneration

open access: yesNeural Regeneration Research, 2015
Multiple-bud regeneration, i.e., multiple amplification, has been shown to exist in peripheral nerve regeneration. Multiple buds grow towards the distal nerve stump during proximal nerve fiber regeneration.

AxonDeepSeg: automatic axon and myelin segmentation from microscopy data using convolutional neural networks [PDF]

open access: yes, 2017
Segmentation of axon and myelin from microscopy images of the nervous system provides useful quantitative information about the tissue microstructure, such as axon density and myelin thickness. This could be used for instance to document cell morphometry

Non-Invasive High-Resolution Imaging of In Vivo Human Myelinated Axons

open access: yesDiagnostics
This work aims to reveal the microscopic (2–3 micrometer resolution) appearance of human myelinated nerve fibers in vivo for the first time. We analyzed the myelinated retinal nerve fibers of a male patient without other neurological disorders in a non ...

Effect of platelet-rich and platelet-poor plasma on peri-implant innervation in dog mandibles

open access: yesInternational Journal of Implant Dentistry, 2019
Background Autologous plasma fractions, such as platelet-rich plasma (PRP) and platelet-poor plasma (PPP), contain growth factors that can enhance neural cell survival and are therefore likely to have the ability to promote nerve regeneration.
