Does the ping between your eyes and brain increase when you're tired?
Does the ping between your eyes and brain increase when you're tired?
Just as stated, I don't the proper way to express it

I don't think the speed of the electrical impulse would change, but yes reaction time would. Perception is more about our brain processing signals than it is about the signals themselves. What you experience yourself as seeing is not the raw image going into your eyes. Slower processing means you're also less likely to see, as in be aware of, details.
This is why tired driving is incredibly dangerous.

You'd be surprised. The speed of electrical pulses inside neurons change due to all kinds of factors, like training and diet.
I do really expect them to change with tiredness too.

Brains are weird so that checks out

Yes. "Slower reaction time" or something is the phrase I'd use. It gets worse if I'm tired.
-
I like that description. I may borrow it the next time I'm asked to run a safety training.
To answer your question, yes. Your reaction time does slow down as you become more tired. The effect is similar to being very drunk. This fact is the basis for Hours of Service regulations in the US trucking industry.

Try Rust. No GC overhead.

🤣

Slower reaction times? Yup. I think Mythbusters even covered it.
-
There have also been several studies that also prove this.
Your driving after being awake for 24 hours is as impacted as though you had a 0.1% BAC (0.08% is the legal limit).

Those driving simulators where you can adjust the reaction time to show how someone impaired would react are scary. And that's just reaction time, a drunk/exhausted person may not even realize how off they are so everything is fine to them.

In the literal sense of the time it takes neuronal spikes to travel from your retina to your visual cortex, no.
What makes it feel that way, I think, is a reduction in the amount of resources your brain is devoting to the real-time modeling of your environment that those visual signals feed into, and that has to be processed before you become conscious of any changes.

This doesn't answer the question, but I think "ping" is a fine way to describe it, as most people will know what you mean. If you want a more technical word, "latency" is a generalized form of "ping".

Too much corruption in RAM, need a power cycle

"Did you try turning yourself off and on again?"
"Yeah, but now I've got post-nut clarity and I'm just sad"

You've been in Elon's programme, haven't you? 😁
-
What program? I'm not aware of Muskrat's doings after his breakup with his fascist tangerine
-
-
Yeah. Also when I'm really tired, I can't play Minecraft because my brain percieves it more as a 2D plane rather than a 3D space.
-
Yes, besides falling asleep at the wheel that's also why you shouldn't drive when tired.
-
Sort of, your processing power does decrease, meaning you'll likely do a worse job of putting what you're seeing into the appropriate context.
-
No but the CPU load slows down processing.
-
You always see at the same speed. Your reaction time slows down.
Think of it this way. You step on a Lego and it hurts instantly. Doesn't matter if you're sleepy or drunk or wide awake. You feel it right away. Same with seeing; it's instantaneous.
