First of all a disclaimer: I'm not suicidal nor homicidal, nor planning to harm anyone. I'm asking purely out of curiosity, knowledge, and respect for people who unjustly died from a bullet wounds So, I didn't find a more appropriate section on this forum, because as strange as the question sounds, it deals with biology and neurons. We see in countless action movies people being killed with a bullet to the head. In most cases, it results in an instant "lights out" (especially if the brain is blown up by the shotgun or magnum shot), but in some movies you can see the victim to stay conscious for a few seconds (especially when small caliber is used). I'm mostly curious what happens in case of a more common caliber, in the range of: 9mm, .38, 5.56, 7.62 So, imagine a typical scene from the movie - a bullet penetrates the brain directly and exits the other side, painting the wall in blood and pieces of brain matter, victim is instantly dead. Or so it seems. What does he really feel in this instant? Does he feel any pain for a moment? I know it happens very fast, but a brain is also capable of transmitting signals very, very fast. And even though all motor functions may cease, how long a conscious can remain until it fades out from this kind of damage? half a second? a second? longer? Are there any scientific knowledge that can help answer those questions? Am I crazy for being curious about this?
