Why does the brain, despite being a very vital organ, not have any pain receptors?
In: 25
Pain is a perception that has evolved to help regulate animal behavior. Nerves help to innervate the body to create that perception of pain in more localized areas of the body and allows parts of the body that are far away from the brain to share information with other parts of the nervous system and brain quickly to make fast motor inputs like moving muscles fast when they sense burning. The brain is creating a perception of pain in the body using the nerves. Since the brain is the one creating the perception of pain in the first place, it does not need nerves to help with that task in the brain because it is those exact structures in the brain that are creating perceptions of pain in the first place, they simply do not need nerves to do that OR one could also argue that the brain IS made of nervous system tissue and therefor it is a nerve-like network that creates a perception of pain, just differently than the body.
It is like asking the dungeon master why they do not need a character sheet to operate. It is because the DM MAKES the character sheets in the first place and does not need a charcter sheet to operate because it (the brain) operates differently than the body.
