Action potential solitons and waves in axons [PDF]
arXiv, 2022 We show that the action potential signals generated inside axons are reaction-diffusion solitons or reaction-diffusion waves, refuting the Hodgkin and Huxley hypothesis that action potentials propagate along axons with an elastic wave mechanism. Reaction-diffusion action potential wavefronts and solitons annihilate at collision and boundaries of axons,

RNA: A publication of the RNA Society, 2011 mRNAs are transported, localized, and translated in axons of sensory neurons. However, little is known about the full repertoire of transcripts present in embryonic and adult sensory axons and how this pool of mRNAs dynamically changes during development.

The Journal of Cell Biology, 2006 ![Graphic][1] Movement of mitochondria (blue and green) does not correlate with axonal advance (yellow). Mitochondria and other cellular subunits are transported from the cell body of neurons toward the growth cone of axons via kinesin-based fast transport.

Advanced Functional Materials, EarlyView.This study introduces a conductive nerve guidance conduit integrated with wireless electrical stimulation through alternating magnetic fields, which induces currents and creates a supportive microenvironment for nerve regeneration. In vivo studies show that this approach significantly enhanced myelin restoration, gastrocnemius muscle regeneration ...

Frontiers in Neuroanatomy, 2018 In this article, we describe the method that allows fluorescently tagged structures such as axons to be targeted for electron microscopy (EM) analysis without the need to convert their labels into electron dense stains, introduce any fiducial marks, or ...

A Stochastic Multiscale Model that Explains the Segregation of Axonal Microtubules and Neurofilaments in Neurological Diseases [PDF]
, 2015 The organization of the axonal cytoskeleton is a key determinant of the normal function of an axon, which is a long thin projection away from a neuron. Under normal conditions two axonal cytoskeletal polymers microtubules and neurofilaments align longitudinally in axons and are interspersed in axonal cross-sections.

Correlated disorder in myelinated axons orientational geometry and structure
, 2017 While the ultrastructure of the myelin has been considered to be a quasi-crystalline stable system, nowadays its multiscale complex dynamics appears to play a key role for its functionality, degeneration and repair processes following neurological ...

The Drosophila immunoglobulin gene turtle encodes guidance molecules involved in axon pathfinding [PDF]
, 2009 Background: Neuronal growth cones follow specific pathways over long distances in order to reach their appropriate targets. Research over the past 15 years has yielded a large body of information concerning the molecules that regulate this process.

The axonal transport of mitochondria [PDF]
Journal of Cell Science, 2005 Organelle transport is vital for the development and maintenance of axons, in which the distances between sites of organelle biogenesis, function, and recycling or degradation can be vast. Movement of mitochondria in axons can serve as a general model for how all organelles move: mitochondria are easy to identify, they move along both microtubule and ...
