Seeing as the brain takes an amount of time to process what we see, around 13 milliseconds, if we are killed, do we die 13 milliseconds before we process our own death? Therefore not experiencing the last 13 milliseconds of our lives?

So when we see an image, it takes 13 milliseconds for the brain to gather all it's shit together and be like, "yup that's this" and for us to then know what we're looking at. If we were, for example, shot in the head, would we die 13 milliseconds before we even knew we were dead, seeing as we see the world at a 13 millisecond delay? The overarching question here is essentially:

Is every human robbed of the last 13 milliseconds of their lives?
