Kimberly WarnerHostUm, Danite, can you tell us a little bit about what happens when, uh, the vestibular system is affected during, um, uh, you know, when it's injured during a concussion and, uh, why that delay might happen as well?

So in specific, so that we sort of answer your question right away, um, the vestibular system itself, a lot of people think of as the inner ear.

And I'd like us to remember that that's the peripheral vestibular system, right? Peripheral always means the outside.

But our vestibular system has all kinds of nuclei, and it's all kinds of connections inside our brain.

So it truly is our sense of balance, and it truly is intertwined with every aspect of our brain because it's extremely important to our bodies to keep our heads above ground and oriented.

Knowing where we are in space, knowing where we are relative to our own bodies is critical to our function, and our body knows that on a visceral level.

So now let's think about the brain, and just not to make everyone be a neuroanatomist.

And right over that, which I think, Jess, I mean, first of all, my heart breaks for you because, and I'm gonna get to that, because the, you know, different things could have been done, right?

But right over this primitive area is our emotional center, and this is something that's so important to remember, is that that's important to get into fight or flight when our primitive systems-

So a concussion different than a more severe, a moderate or severe traumatic brain injury.

It's considered a mild traumatic brain injury, and the reason for that is because we expect full recovery.
