摘要: To examine the specific effects of cutaneous pain on electroencephalographic (EEG) activities, tonic painful and non-painful sensations in left forearm were induced by intradermal injection capsaicin 100 μg/20μl same volume vehicle, respectively, 15 healthy males. The EEG data acquired five experimental conditions: (i) baseline A; (ii) vehicle injection; (iii) B; (iv) (v) waning pain, analyzed compared with analysis variance. Only evoked significant decreases theta, alpha-1 alpha-2 powers over centro-parieto-occipital regions B. No difference activation between was found. This implicates that observed topographic is not for but probably related to stimulation.
