It's not going to be putting so much blood flow, oxygen, energy into maintaining a pathway because

Because a pathway in the brain, all pathways require a lot of nutrients.

Really strengthened pathways require a lot of oxygen, nutrients, blood flow, all these other, you know, like neurochemicals to keep it going.

So it's not going to keep a pathway going if it's not used enough.

So the remnants will stay there.

But for it to be this thick, strong highway, not worth it for the brain.

It's not fucking worth it, which is great in our favor.

but it's also not good for things that we want.

Like the whole idea of like, you know, when you learn a language as a second language, it's a whole, if you don't use it, you lose it thing.

So it's good.

And it's also bad for the things that we want to maintain.

We have to be using it all the time for it to stay nice and strong.

Now, fun fact, well, it's not a fun fact.

It's actually a very sad fact about myelin.

I said these strongly myelinated efficient neural circuits, myelin is

is kind of this fatty sheath that wraps around the axons.

Now we know that the axon, or we may or may not know, but the axon is the part of the cell, the neuron, that sends information to the next neuron, the next cell.

Now that axon, you know, sometimes they're really long

And even when they're not long, they are myelinated.

So it's this kind of, it's a cell called oligodendrocyte.
