The shape (amplitude and latency) of single cortical responses to argon laser stimulation was found to match six perceptual classes: three pre-pain and three pain. The amplitude of the pain related single cortical responses correlated with the perceived feeling of pain. Easy detectable responses were obtained because habituation to the stimuli was reduced and a high degree of attention was given to each stimulus. Single cortical responses to argon laser stimuli are suggested as a new quantitative technique with application in the assessment of function in the thermal and nociceptive pathways.
发现单次皮层对氩激光刺激的反应形状(振幅和潜伏期)与六种感知类别相匹配:三种疼痛前类别和三种疼痛类别。与疼痛相关的单次皮层反应的振幅与感觉到的疼痛程度相关。由于减少了对刺激的习惯化并对每个刺激给予了高度关注,因此获得了易于检测的反应。单次皮层对氩激光刺激的反应被认为是一种新的定量技术,可用于评估热和伤害感受通路的功能。
