Abstract Brain assembly is hypothesized to begin when pioneer axons extend over non-neuronal cells, forming tracts guiding follower axons.
A long fiber called the axon extends from the cell body and is coated with a protective sheath called myelin, which acts like insulation on a wire, protecting the axon and facilitating sending and receiving electrical signals.

Similarly, rat neurons extended axons into the grafted material and cells.
Axons of these nerves leave the spinal cord in the ventral branches (rami) of the spinal nerves, and then separate out as «white rami» (so called from the shiny white sheaths of myelin around each axon) which connect to two chain ganglia extending alongside the vertebral column on the left and right.
In these mice, 90 per cent of the axons in the SC had extended into the wrong areas.
Neurons need large amounts of energy to extend their axons long distances through the body.
These observations prompted us to replace the eye field with EFTF - expressing pluripotent cells to ask if the induced retinal cells could generate a normal eye and if induced retinal ganglion cells would extend axons to and synapse with their normal tectal targets.
In the peripheral nervous system, myelin forms when «membrane tongues» extend from Schwann cells to spirally wrap around an adjacent axon.
The reprogrammed cells formed all seven classes of retinal cells normally found in the eyes, including the retinal ganglion cells, which have axons (optic nerves) that extend to the brain.
We are using these new tools to image the structural features of individual cells, such as the cell body and the axons of the cells, which are long fibers that extend from each neuron, together forming the optic nerve that transmits visual information to the brain.
For this we inject themselves into the vitreous, into the center of the eye, and what we're finding is that a subset of the injected retinal ganglion cells can go into the retina, the green cells are the donor cells, they extend all of their axons and dendrites.
The labelling is for acetylated tubulin in red (identifying all axons), and green for the cell permeable dye calcein, which is only applied on the axonal side of the chambers (top half) and allows the identification of those neuronal cell bodies (bottom half) that have extended axons to the other side of the microfluidic device.
V2a interneurons are, in fact, some of the longest cells in the body, able to extend their axon — the nerve fibers that transmit electrical impulses — across several vertebrae.
Lower motor neurons have somas within the spinal cord and extend their axons peripherally to innervate skeletal muscles.
