Frontiers in Neural Circuits, 2022 Neurons in the mouse primary visual cortex (V1) exhibit characteristic response selectivity to visual stimuli, such as orientation, direction and spatial frequency selectivity. Since V1 receives thalamic visual inputs from the lateral geniculate nucleus (

Unrestrained growth of correctly oriented microtubules instructs axonal microtubule orientation
eLife, 2022 In many eukaryotic cells, directed molecular transport occurs along microtubules. Within neuronal axons, transport over vast distances particularly relies on uniformly oriented microtubules, whose plus-ends point towards the distal axon tip ...

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.

Local Accumulation of Axonal Mitochondria in the Optic Nerve Glial Lamina Precedes Myelination
Frontiers in Neuroanatomy, 2021 Mitochondria are essential for neurons and must be optimally distributed along their axon to fulfill local functions. A high density of mitochondria has been observed in retinal ganglion cell (RGC) axons of an unmyelinated region of the optic nerve ...

The Genetics of Axonal Transport and Axonal Transport Disorders
PLoS Genetics, 2006 Neurons are specialized cells with a complex architecture that includes elaborate dendritic branches and a long, narrow axon that extends from the cell body to the synaptic terminal. The organized transport of essential biological materials throughout the neuron is required to support its growth, function, and viability.

Human umbilical cord mesenchymal stem cells promote peripheral nerve repair via paracrine mechanisms
Neural Regeneration Research, 2015 Human umbilical cord-derived mesenchymal stem cells (hUCMSCs) represent a promising young-state stem cell source for cell-based therapy. hUCMSC transplantation into the transected sciatic nerve promotes axonal regeneration and functional recovery.

Interferon inhibits the release of herpes simplex virus-1 from the axons of sensory neurons
mBio, 2023 Herpes simplex virus-1 (HSV-1) has evolved mechanisms to evade the host immune system and limit the antiviral effects induced by interferon (IFN) produced by local epithelial and immune cells.

Axon Membrane Skeleton Structure is Optimized for Coordinated Sodium Propagation [PDF]
PLOS Computational Biology, 13, Issue 2, e1005407, (2017), 2016 Axons transmit action potentials with high fidelity and minimal jitter. This unique capability is likely the result of the spatiotemporal arrangement of sodium channels along the axon. Super-resolution microscopy recently revealed that the axon membrane skeleton is structured as a series of actin rings connected by spectrin filaments that are held ...

Axon and Myelin Morphology in Animal and Human Spinal Cord
Frontiers in Neuroanatomy, 2017 Characterizing precisely the microstructure of axons, their density, size and myelination is of interest for the neuroscientific community, for example to help maximize the outcome of studies on white matter (WM) pathologies of the spinal cord (SC).

Polychlorinated Biphenyls (PCBs): Risk Factors for Autism Spectrum Disorder?
Toxics, 2020 Autism spectrum disorder (ASD) includes a group of multifactorial neurodevelopmental disorders defined clinically by core deficits in social reciprocity and communication, restrictive interests and repetitive behaviors.
