摘要: Publisher Summary This chapter discusses the Regional brain oxygenation during phasic and tonic painful stimulation. Painful stimuli activate various areas. It has been discussed that this multiple activation pattern is a strong indication of parallel processing nociceptive input to cerebral cortex. Besides lateral somatosensory system which receives from contralateral body side, ipsilateral cortical areas are involved, in particular SII insular cortex, frontal cortex midline structures. Phasic pain these regions differentially. The projection system, SI more strongly activated by than stimuli. seems be mainly concerned with stimulus transients. In contrast, used study were activating ACC efficiently agreement notion important for unpleasant affective component pain.
