axonal

The immune system in the brain is used to remove axonal connections between different neurons...

In these situations, the biggest damage to the brain is something called diffuse axonal injury where rotational forces from the sudden acceleration and deceleration cause injury to the neurons.

An aspect of brain injury is diffuse axonal injury or when your brain undergoes unreasonable acceleration.

The cause of death is often metabolic stress caused by axonal damage near the lamina cribrosa (where fibers exit the eye).

Only a small fraction of an axonal arbor — its collection of presynaptic terminals—-is functionally and reliably coupled to postsynaptic targets.

Except than in brain development the general trend is to lose a large fraction of many neuron types, synapses, and excess axonal connections.

Can you elaborate on how the axo-axonal transmissions blow up our simple models?

You're moving, meaning you're hit at an angle, meaning that there's a potential for a diffuse axonal injury[1]: the rotational component of the injury.

My friend added, then scientists discovered that this mini brain and axonal connection already exists in the gut and develops a way to reactivate it.

In the adrenal medulla, the primary messenger is an axonal depolarization.

Functional connectivity is functional more relevant than mere axonal connectivity.

The axonal propagation of action potentials is...

They refer to their model as "single-compartment phenomenological spiking neurons, learning synapses with spike-timing dependent plasticity, and axonal delays" in their The cat is out of the bag article.

Pathogenesis of ganglion “cell death” in glaucoma and neuroprotection: focus on ganglion cell axonal mitochondria.

In my relative's case there was evidence "suggestive" of DAI (diffuse axonal injury) which may explain why his deficits are so profound, but nobody can say.

"it is not uncommon for axonal propagation of action potentials to happen in both directions" - suggesting they are optimized to continuously operate in multidirectional way.

Axonal injury is a key trigger in many cases.
