Physiology of Pain

What is it about?

We give different characters to the pain. If a child is injured, he will cry and say, "I have a wound". The mother will ask: where does my love hurt? Consider that these are two different approaches to pain: 1. The emotional element of pain, which is phylogenetically primitive and deals with pain as something unpleasant, which must be avoided and the most recent: 2. the distinct element of pain, which is the ability to perceive exactly where the pain is and to respond appropriately.

Why is it important?

Pain in the cortex: It was commonly said that the structures of the cortex only superficially deal with the perception of pain, if not at all. This is wrong, as a multitude of connections link higher structures of the cortex to centers of pain in the chamber and the brainstem. Important structures of the cortex are: The primary aesthetic cortex (sensory cortex) The secondary aesthetic cortex The anterior part of the central lobe of the cerebral hemispheres (insula) The adductor propeller The primary cosmetic cortex is responsible for detecting pain. The adductor helix is related to the emotional element of pain. The chamber is the central transmission station of pain. Several of its nuclei deal with pain. The lateral nuclei deal with the aesthetic / discrete element of pain and the inner nuclei deal with the emotional element of pain.
