Sentences with phrase «axons grew»

And in transgenic pups whose optic nerves were surgically severed 4 days after birth, retinal axons grew around the gap, finding their way to the proper target areas in the brain.

Some of the axons grew as much as 1.5 millimeters, connecting to the corpus callosum, a bundle of neurons connecting the left and right cerebral hemispheres.

Some RGC axons grew all the way back to the brain's visual - processing areas.

The researchers set up a system to grow asymmetric nerve cells in an observation chamber and use live cell imaging to track how rabies virus particles are transported along the axons.

However, when the researchers grew nerve cells that had no p75NTR in their observation chamber, they found that virus transport along the axon is less frequent and much slower.

How mammalian axons end up at their final destination in the growing brain remains a mystery.

Axons that are supposed to grow into the muscle on the eye's inner edge may end up on the outer edge instead.

For a damaged nerve to regain function, its long, signal - transmitting extensions known as axons need to grow and establish new connections to other cells.

«To reach their target, growing axons rely on molecules known as guidance cues, which instruct them on which direction to take by repelling or attracting them to their destination,» explains Dr. Charron, Director of the Molecular Biology of Neural Development research unit at the IRCM.

This shows that scars are capable of producing chemical signals, albeit faint ones, that permit axons to grow over them.

Now, they have discovered that — in the developing brain of a fruit fly — APPL ensures that the axons are long enough and grow in the correct direction.

To connect with other neurons into circuits, neurons grow long branch - like structures called axons and dendrites.

As the neurons grow on each side, they sprout long branches, called axons, which creep down the grooves to make contact with neurons growing on the other side in order to transmit electric signals between them.

The researchers found that new neurons arose in the higher vocal centre (HVC) and grew extensions (axons) 3 millimetres long — long enough to reach another brain region, the nucleus robustus archistriatalis (RA).

Another possible way to make nerve impulses travel more slowly involves growing longer axons, so that signals have a greater distance to travel.

When the researchers exposed goldfish axons to rat Nogo - A, the nerves stopped growing.

Theses landmarks are then recognized by growth cones at the tip of axons — the projections that grow out from the retinal neurons and into the brain.

Disrupting either the Wnt or ephrin pathway throws the growing axons off their targets, shifting the map from side to side.

In theory, a transplanted organ could hack into its host's nervous system by growing axons that connect with the host's cells.

The cells in green have electric charges on their membranes that keep the axons from growing.

That made sense, they realized, because the new eye wasn't growing many new axons.

The findings help explain how axons, the long projections of nerve cells, grow toward and across an organism's midline whether in the mammalian spinal cord or its equivalent structure in flies and...

In particular, what are the molecular mechanisms underlying the ability of long - range projecting pyramidal neurons and locally - projecting interneurons to form an axon, for these axons to grow and branch and finally find their appropriate synaptic targets?

These endosomes are responsible for transporting material around cells and for degrading proteins including ones that signal neurons to grow the elaborately branched axons and dendrites that form neural connections.

Our hypothesis is that endocannabinoids are enriched at high concentration within tips of the growing axons.

This is when neuroplasticity steps in and new connections (dendrites, synapses, myelinated axons) physically grow between formerly separate memory circuits when they are activated together.

A research team led by Michal Schwartz of Israel's Weizmann Institute of Science grew these immune cells in a laboratory and implanted them into rats, and the transplants of the cells caused the axons to regenerate.

The latest study underscores a growing appreciation among neuroscientists for the importance of the brain's «white matter» — fat - covered clusters of axons that string neurons and the brain's two hemispheres together — in brain function.
