Definitions for nociception
This page provides all possible meanings and translations of the word nociception
The physiological process underlying the sensation of pain.
Nociception is defined as "the neural processes of encoding and processing noxious stimuli." It is the afferent activity produced in the peripheral and central nervous systems by stimuli that have the potential to damage tissue. This activity is initiated by nociceptors, that can detect mechanical, thermal or chemical changes above a set threshold. Once stimulated, a nociceptor transmits a signal along the spinal cord, to the brain. Nociception triggers a variety of autonomic responses and may also result in a subjective experience of pain in sentient beings. Nociceptive neurons generate trains of action potentials in response to painful stimuli, and the frequency of firing signals the intensity of the pain.
