axons

A neuron has hundreds to thousands axons and dendrites and connect with other neurons in a dense network.

Apparently the communicating tissue between the axons in my brain had been going away for quite some time.

For a brain, there are a finite number of neurons with a finite number of dendrites and axons.

This is because the visualization is basically just a graph, with axons as edges and neurons as nodes, and then signals are propagated with extremely simple graph-traversal style logic.

I'd bet that the slowness of octopuses is not due to neuron count, but due to outmoded axons.

Myelin is a lipid sheath surrounding axons, very roughly analogous to cable insulation.

The axons of a giant squid are up to a millimeter in width.

Neurons pass signals along axons as a wave of an action potential[2].

If we can image sub-cellular features, what makes you believe we can't trace all the axons, dendrites and the synapses?

The connections (axons and dendrites) are the active processing units.

I think what is much more intractable is actually massive amounts of axons you'd need to reconnect, and you'd need extremely good classification to connect the right axons from host body and brain together.

Neurons don't necessarily die, but axons disappear.

It is this "clean cut" the key to spinal cord fusion, in that it allows proximally severed axons to be "fused" with their distal counterparts.

"This thing you think of as you: it spreads across two cerebral hemispheres connected by the corpus callosum, a fat meaty pipe more than 200 million axons thick." From the article.

Ask yourself, "From what did this community start?" That nerve is the focus from which dendrites sprout and axons connect and so I'll get off my soap box after I say, I still love hacker news.

Again, how is this attributed to "creativity" and not to "scientists know that the structures of dendrites and axons neurons vary widely but still they are quite narrow so that's how they draw them"?

Axons and even synaptic vesicles are kept intact.
