If I’m remembering correctly vision is movement based, but animals have lots of ways to deal with it. Humans and other species that can move their eyeballs just like vibrate their eyes. But birds like chickens rely more on head bob I think. Couldn’t tell you what kind of muscles a tyranasaur has in its eyes.

Also being wrong on the Internet is the best way to find the right answer. So tell me how I’m wrong.

What do you mean stop damaging it? What makes it sound like I’m not working with my brain? What makes it sound like I’m not exercising my brain?

No I’m not going to stop doing sports. I’m doing a lot to work with my brain, and I’m always learning something new.

I’m learning sumi-e painting to go with my calligraphy, I’m taking the time to get back into programming. This is my second year mountain biking and I’ve gotten pretty good at it over the summer. I journal every day and reflect, I’ve been making a lot of progress being less critical of myself. In doing all those things I’ve felt my social skills slip, so now I’m putting in the effort to be around people more and be vulnerable around them.

And yet I can feel places where my brain isn’t as strong as it used to be. I’m accepting of that and trying to love myself in spite of my shortcomings. I don’t need to optimize for everything, I can just focus on what’s important to me.

My friend is going through concussion rehabilitation right now and is working with one of the best doctors in the field. She has not been prescribed any medication at all. It’s been 9 months maybe? Right now she’s onto the stage where she need to get her heart rate up with exercise. Though it took a long time for doctors to actually start taking her symptoms seriously and she bounced around between a lot of them before she got where she is now.

We’ve had lots of talks about the recovery process, how you can train your brain to get better at certain things. And I’ve been doing lots of stuff to train my brain. But still friends will bring up symptoms they have and I’ll be like, oh shit I didn’t know that was concussion related!

But I think some of my symptoms are just going to be there for life. Language processing, memory (some memory has improved with training but sometimes I just get stuck and can’t think of a word or name or whatever), visual artifacts, sound sensitivity, and I don’t know if it’s related but I definitely get depressed.

I think with training you can improve your life experience, but I’m not sure you’ll ever get back to what it would be like without a concussion. Also I’m sure the 4-7 years of binge drinking didn’t help either.

Currently 29. Noticed mental decline after concussions in my youth and a few years of heavy drinking. I don’t fall on my head as much and I don’t really drink anymore, but I’m not sure how much of what I’ve lost I’m going to get back.
