The sound of an axon's growth [PDF]
Phys. Rev. E 99, 050401 (2019), 2018 Axons are linear processes of nerve cells that can range from a few tens of micrometers up to meters in length. In addition to external cues, the length of an axon is also regulated by unknown internal mechanisms. Molecular motors have been suggested to generate oscillations with an axon length-dependent frequency that could be used to measure an axon ...

Modeling of interstitial branching of axonal networks [PDF]
1. J. Integr. Neurosci. 12, 1-14, (2013), 2013 A single axon can generate branches connecting with plenty synaptic targets. Process of branching is very important for making connections in central nervous system. The interstitial branching along primary axon shaft occurs during nervous system development. Growing axon makes pause in its movement and leaves active points behind its terminal. The new

Currents carried by sodium and potassium ions through the membrane of the giant axon of Loligo
Journal of Physiology, 1952 In the preceding paper (Hodgkin, Huxley & Katz, 1952) we gave a general description of the time course of the current which flows through the membrane of the squid giant axon when the potential difference across the membrane is suddenly changed from its ...

A model of fasciculation and sorting in mixed populations of axons [PDF]
Phys. Rev. E 84, 021908 (2011), 2010 We extend a recently proposed model (Chaudhuri et al., EPL 87, 20003 (2009)) aiming to describe the formation of fascicles of axons during neural development. The growing axons are represented as paths of interacting directed random walkers in two spatial dimensions.

Node of Ranvier length as a potential regulator of myelinated axon conduction speed
eLife, 2017 Myelination speeds conduction of the nerve impulse, enhancing cognitive power. Changes of white matter structure contribute to learning, and are often assumed to reflect an altered number of myelin wraps. We now show that, in rat optic nerve and cerebral

Frontiers in Aging Neuroscience, 2022 IntroductionThe typical symptoms of Alzheimer’s disease (AD) are cognitive impairment, disrupted spatial orientation, behavioral and psychiatric abnormalities, and later motor deficits. Neuropathologically, AD is characterized by deposits of pathological

Estimation of electric field impact in deep brain stimulation from axon diameter distribution in the human brain [PDF]
Biomedical Physics & Engineering Express 2021, 2021 Background: Finite element method (FEM) simulations of the electric field magnitude (EF) are commonly used to estimate the affected tissue surrounding the active contact of deep brain stimulation (DBS) leads. Previous studies have found that DBS starts to noticeably activate axons at approximately 0.2 V/mm, corresponding to activation of 3.4 $\mu$m ...

Humanized tau antibodies promote tau uptake by human microglia without any increase of inflammation
Acta Neuropathologica Communications, 2020 Immunotherapies targeting pathological tau have recently emerged as a promising approach for treatment of neurodegenerative disorders. We have previously showed that the mouse antibody DC8E8 discriminates between healthy and pathological tau, reduces tau
