Hello. I'm not a biology student, so this may come as a stupid question to those that are. Anyways, here it is: if we cut open someone's skull, prod their brain, they won't feel pain;but, if we were to cut off one of their limbs they would. What is exactly experianceing the pain? Where is pain located?

lol actually a good question imo.Originally Posted by Chris11
My guess is that the pain is located where the pain actually is, and the brain is just the "middleman" transmitting the order for the nerves there to feel the pain or something.
Hello, I am not a biology student either.
The way I understood it is that we need sensory nerves to receice the stimuli. The nerves then sends a signal to the brain which interprets it as "bad stuff happening" and the location of said bad stuff. Our conscious self gets this information as a feeling of pain at the location where the stimuli emerged from. (Our body may already have reacted to the pain by then)
The reason we do not feel pain when someone is prodding your brain is because we do not have any sensory nerves there.
To make an analogy: Your computer registers when you press a button, but if you were to physically touch the processor it wouldn't register that. Despite being potentially more harmful to it than the ctrl-alt-delete command.
Pain is transmitted by the nervous system. The brain, for various reasons does not have nerve endings of its own, therefore it cannot feel anything - heat, cold, notta.
Our bodies are full of nerve endings used to tell us such important things as: hey, get that foot out of that fire before it burns to a crisp. Signals are sent to the brains which interprets it as pain.
In cases of fibromyalgia, something is screwed up: the brain interprets sensations such which are NOT pain, as pain.
