A model of fasciculation and sorting in mixed populations of axons [PDF]
Phys. Rev. E 84, 021908 (2011), 2011 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.

Sound of an axon's growth [PDF]
Physical Review E, 2019 Axons are linear structures 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'

Why do axons differ in caliber? [PDF]
Journal of Neuroscience, 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.

An action potential initiation mechanism in distal axons for the control of dopamine release
Science, 2022 Information flow in neurons proceeds by integrating inputs in dendrites, generating action potentials near the soma, and releasing neurotransmitters from nerve terminals in the axon.

Frontiers in Computational Neuroscience, 2023 The self-organization of the brain matrix of serotonergic axons (fibers) remains an unsolved problem in neuroscience. The regional densities of this matrix have major implications for neuroplasticity, tissue regeneration, and the understanding of mental ...

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 ...

Multiple Copies of microRNA Binding Sites in Long 3′UTR Variants Regulate Axonal Translation
Cells, 2023 Rapid responses to changes within subcellular compartments of highly polarized cells, such as neuron axons, depend on local translation and post-transcriptional regulation.

Advanced Engineering Materials, EarlyView., 2023 This study aims to explore the feasibility of using a structure inspired by the features of horsetail and human spine as the potential helmet liner, targeting at mitigation of acceleration‐induced injuries. A parametric study is conducted to investigate the effect of individual geometrical variables in the design, indicating its capability to reduce ...

The Requirement of Sox2 for the Spinal Cord Motor Neuron Development of Zebrafish
Frontiers in Molecular Neuroscience, 2020 Sex-determining region Y box 2 (Sox2), expressed in neural tissues, plays an important role as a transcription factor not only in the pluripotency and proliferation of neuronal cells but also in the opposite function of cell differentiation. Nevertheless,
