Suppression of first pain and slow temporal summation of second pain in relation to age.
BACKGROUND Thermal stimuli delivered to skin of the arms or legs can produce a sensation of two distinct pains. These pains have been associated with activity in A-delta (first pain) and C-fiber (second pain) nociceptive fibers, respectively. Under appropriate conditions first pain decreases in intensity (adaptation) while second pain increases in intensity (slow temporal summation). Change in ...
متن کاملA closer look at temporal summation of second pain in healthy persons.
Quantitative sensory testing (QST) is an important tool in pain research. Using these methods, quantitative data regarding the perception of pain associated with pain states, treatment and other factors can be studied using the application of controlled sensory stimuli to the subject. One limitation of research employing these techniques, however, is that evoked stimuli typically stimulate mult...
متن کاملPain catastrophizing is related to temporal summation of pain but not temporal summation of the nociceptive flexion reflex.
Pain catastrophizing is associated with enhanced temporal summation of pain (TS-Pain). However, because prior studies have found that pain catastrophizing is not associated with a measure of spinal nociception (nociceptive flexion reflex [NFR] threshold), this association may not result from changes in spinal nociceptive processes. The goal of the present study in healthy participants was to ex...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اولTemporal summation of trigeminal pain in human anterior cingulate cortex
Temporal summation of nociceptive inputs in trigeminal networks can induce central sensitization and maintain chronic pain. We combined functional magnetic resonance imaging and electrically evoked pain-related potentials (PREP) in healthy human subjects to identify brain regions involved in temporal summation of nociceptive inputs. We stimulated the skin innervated by the ophthalmic division o...
