#Myeline

[biologist4ever]

In the neuron, a protective covering called myelin insulates the axon and increases the speed of electrical communication along the length of the neuron

No Myelin, I don’t think that a pickaxe can solve this.

Crossing the Node

Nerve axons – slender projections, the route of signals from neurons to other cells – are insulated with a sheath called myelin to ensure signals stay on track, however, there are specialised gaps in the wrapping at Nodes of Ranvier which aid signal conduction. This study, using time-lapse microscopy in live mice, investigates how these nodes impact the essential transport of neurons' contents such as mitochondria (highlighted here in cyan) and endosomes (in magenta) along the axons, providing insight into nerve function in health, injury and disease

wait so what else is up with awoken amethyst besides the reflection thing

oh boy oh boy oh boy do I have an essay for you! it's mostly irl nerd stuff, but!!

Awoken amethyst is nothing like amethyst from Earth! Actual amethyst is almost always purple [but can have blue as a secondary hue], usually has color zoning and belongs to the hexagonal crystal family. Awoken amethyst is blue, has no color zoning, and has a pentagonal structure [which doesn't occur naturally]. Also, a lot of it hums and glows!

It is so unlike actual amethyst that it has been compared to a variety of other gems/minerals, including azurite, fluorite, tanzanite, sodalite/lapis lazuli and agate. So far, the Oracle Engine seems to be the main exception:

"But some of it looks purple. Why is that?" Good question! From what I've seen, it comes down to lighting and backlighting. In the Confluence and Blind Well, Awoken amethyst looks purple in the shadows but is blue when you step back. In The Corrupted strike and seasonal areas like the Coil, it's the opposite - it's purple from afar yet blue up close. The Last Wish raid shows it in purple backlighting at first, before giving way to its true color (blue).

Something something "nothing is as it seems," I suppose.

There is one more exception besides the Oracle Engine, however. And I think it's an interesting one. At the very back of Harbinger's Seclude, by the statue of the first Awoken queen Alis Li, the arches are clearly purple and resemble polished irl amethyst. What does it mean? I have no idea, I'm not a lore expert. But I wouldn't be surprised if it did mean something.

Other than that, I only know the standard lore stuff about Awoken amethyst. It's a symbol of Awoken royalty, it can be created thru Awoken favor, Techeuns use it to enhance their powers, it was once given as diplomatic gifts to Eliksni, so on and so forth. And yes, Mara did wish for the Dreaming City to be built out of amethyst.

Being a rockhound and aspiring mineralogist [and Awoken lore enthusiast], I'm always on the lookout for amethyst-related lore, but this is all I've got at the moment lol. Also I don't know if I actually answered your question but thank you for the Ask!!

Here is a screenshot of my Hunter as a token of my appreciation:

You should be in a 24/7 flow-state with all chakras aligned. Your cerebral spinal fluid should be flowing both ways. There should be zero myelin sheath dividing your brain hemispheres.

would you let it ramble about things it pretends to know a lot about to you

[alveolaraspergillosis]

my parents got me this massive thing of fish oil capsules "for your mental health" because "omega 3s important for myelination" (dont ask me how i feel about this gesture as a vegan or as a neuroscientist in training or as someone with vague anti psychiatry inclinations) but anyway they spent a lot of money and i ve been taking it for the past week . and i think roka can tell its fish oil cuz shes actually interested in these (unlike my meds or my supplements) . anyway my parents' new thing is "you should let her have a fish oil capsule sometimes" she gets alaskan herring oil as a supplement from the pet store she doesnt need the GNC omega 3 blend

I swore to myself that I would post on time for all of hypno ship week, but procrastination hit hard and then compulsion hit harder. My stupid brain just wants to plan a fleshed out hypno-centric coffee shop au because I remembered a song with an ✨inspiring✨ name and now I'm in too deep to pretend I never thought of it.

Regardless... I guess my hypnoshipweek fanfics will all be a part of one big coffee shop au because I fr can't get this shit out of my brain.

Like, I'm taking notes and everything... I never do that kind of shit. 😭😭😭
