Finally, we correlated the fraction of unmyelinated sciatic nerve axons in individual rats (of all treatment groups) with their individual motor performance (Fig. 4e). This yielded an inverse ...

The RNFL comprises of unmyelinated axons originating from the retinal ganglion cell bodies. During acute optic neuritis onset, RNFL thickness first increases due to optic nerve swelling during ...

In a provocative new study, scientists challenge a fundamental tenet in neuroscience about the shape of axons -- the long, thin filaments radiating from nerve cells that transmit electrical ...

In a study, scientists challenge a fundamental tenet in neuroscience about the shape of axons -- the long, thin filaments radiating from nerve cells that transmit electrical signals from cell to ...

Here, we demonstrate that unmyelinated axons of the mouse central nervous system have nonsynaptic, nanoscopic varicosities ~200 nm in diameter repeatedly along their length interspersed with a thin ...

The human brain is white and gray in color because it makes its very own cholesterol. Neurosteroids offer exciting novel treatment for some mental illnesses.

Myelinated vs unmyelinated Myelination refers to whether or not the axon of a nerve is coated with a myelin sheath. Myelin sheaths provide insulation to an axon, which enhances the speed at which ...

A simple electrical model of the nerve axon is presented. The only non-linear element in the model is the sodium conductance, which is assumed to vary in a step-like way. This allows the propagation ...

In the grey matter, these axons are mainly unmyelinated, meaning they are not covered by a whitish-colored, fatty protein called myelin. The grey matter serves to process information in the brain.

Myelination enables action potentials to travel down the axon faster than an unmyelinated one. The color gray in gray matter comes from the neuronal cell bodies it contains and has mostly ...

The fractions of the Piezo1+ myelinated and unmyelinated axons of all Piezo1+ axons were analyzed on electron micrographs taken from the radicular pulp, the core of the coronal pulp, and the ...
