Pain Mechanism

If there is physical damage in a part of body, may it be caused by either injury or disease, not attending to it can worsen the situation. In the absence of pain mechanism mentioned below, if a person is not aware of such damage, he will not engage in the decision making process that will lead to him executing suitable actions to cure and/or take measures to prevent it in future.

What's more, even when VP's capability of making free will decisions offers best solutions based on the current environment and conditions (more under title Free Will – in detail), as it is a free agent, it has the freedom to consider the contents of perceived interaction or ignore it. To defeat possibilities of ignorance such freedom offers in the cases of damage in the body, the evolutionary process has designed the mechanism of pain, which not only alerts VP on a continuous basis, but compels it to intramurally process the damaged area in the IPS, as follows:

Pain receptors (called nociceptors) send sensory data in the similar way as touch receptors, but generate much higher intensity values (though using different processes and pathways). Their intensity values are proportional to the severity of damage, which can generally be determined by (additional to algorithms hard-wired to process and determine the same) the amount and type of pain receptors involved in the damaged area, which are designed and distributed by the evolutionary process to facilitate the same (i.e. evaluate severity), in the best way possible by such arrangement.

In loose terms, higher the damage, the more intensity values pain receptors produce (besides other reasons for assigning high intensity values), which are sent by LB to VP. Based on such high intensity values, VP assigns consciousness to the area involved in the damage, producing equally high sensation, which alerts VP (more under title Attention Mechanism).
