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.

    Yes. “Slower reaction time” or something is the phrase I’d use. It gets worse if I’m tired.

    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.
