Nociceptive afferents open and non-nociceptive afferents close a gate to the central transmission of noxious input. If the brain perceives the threat as credible, it creates the sensation of pain to direct attention to the body part, so the threat can hopefully be mitigated; this process is called nociception It is always subjective.
