Phasic and Tonic Pain Differentially Impact the Interruptive Function of Pain
The interruptive effect of painful experimental stimulation on cognitive processes is a well-known phenomenon. This study investigated the influence of pain duration on the negative effects of pain on cognition. Thirty-four healthy volunteers performed a rapid serial visual presentation task (RSVP) in which subjects had to detect (visual detection task) and count the occurrence of a target lett...
متن کاملTonic pain attenuates phasic pain
Pain perception is closely related to the attentional level and the vigilance of the subject [4]. The intensity of a pain stimulus and its sensation do often not coincide. A common experimental example is the so-called pain-inhibiting-pain effect: A stressful stimulus, e.g. persistent or chronic pain, often elevates the threshold for brief pain stimuli applied during the same time. Stressful st...
متن کاملTHE EFFECT OF LOCUS CERULEUS LESIONING ON TONIC AND PHASIC PAIN
Bulbospinal noradrenergic pathways are shown to have an important role in descending inhibition of pain sensation. Locus ceruleus (LC), as a rich noradrenergic nucleus in the brain stem which has projections into the dorsal horn of the spinal cord, was evaluated for antinociceptive activity by using tonic and phasic pain models in the rat. LC-lesioned rats demonstrated moderate increase in ...
متن کاملAnalgesic effect of electrical stimulation and microinjection of L-glutamate into the paragigantocellularis nucleus on phasic and tonic pain
The paragigantocellularis (PGi) nucleus constitutes a large portion of the ventral pontomedullary reticular formation. Neurons within the PGi have been implicated in a variety of functions including cardiovascular regulation, respiratory control, pain and analgesia. Investigators have demonstrated that electrical stimulation and microinjection of L-glutamate into the PGi produce antinocicepti...
