Circular pain model Flashcards
Which networks of the brain does conscious neural activity of pain engage in?
sensory, cognitive, and emotional networks
T/F: Often, a painful experience will involve activity of all of the networks?
True
Why was the circular pain model developed?
in order to explain the multidimensional nature of the experience of pain
What are the 3 main interactive components of the painful experience? (circular pain model)
- Nociceptive component
- A sensory-discriminative component
- Affective-emotional component
Are the 3 components of the circular pain model independent or connected?
They can act independently, but also influence each other
Goals of the circular pain model?
- Explain the multidimensional nature of the pain experience
- Emphasize the complexity and interdependence of the components which contribute to the experience of pain
- Provide health professional with a model of pain that enables him/her to comprehend the different components involved in the pain experience
- resulting in appropriate treatment
Nociceptive component of pain involves activation of nociceptors by noxious……
mechanical, thermal, and/or chemical stimuli
Where do the afferent electrical impulses from the nociceptors go?
target areas of the CNS
somatosensory cortex, insula, frontal lobes, limbic system and others
Sensory-discriminative component of pain is result of activity where?
somatosensory and insular cortex
The somatosensory and insular cortex allow the person to identify what about pain?
the type, intensity and bodily location of the noxious event
T/F: Sensory-discriminative component of pain can be present and cause pain without physiological nociception.
True
The affect-emotional component of pain response is mediated by what system?
limbic system
Affect-emotional component of pain pertains to…
the affective (emotional) response and associated behavior resulting from the initiating noxious event or stimulus - response can be generated by nociception or other unpleasant experience
