疼痛受到认知因素的调节，包括注意力和情绪。在这项研究中，我们评估了审美的分心影响主观评定疼痛（视觉模拟评分;VAS）和多通道诱发电位的CO2激光刺激的左手在12名健康志愿者。受试者在没有其他外部刺激（基线条件）的情况下接受激光刺激，同时观看他们先前评为美丽，中性或丑陋的不同画作。以前认为美丽的绘画作品产生较低的疼痛评分和P2波振幅的明显抑制，位于前扣带皮层; P2波振幅的抑制较小或不显着，分别在介绍丑陋或中性的绘画。偶极源定位分析的LEP峰值显示了显着的变化，在不同的条件下，与右扣带皮层从后方到前方的转移，而在以前被评为beautiful.Our结果提供的证据表明，疼痛可能是调制在皮层水平的美学内容的分心的刺激。(c)2008年爱思唯尔公司All rights reserved.
Pain is modulated by cognitive factors, including attention and emotions. In this study we evaluated the distractive effect of aesthetic appreciation on subjectively rated pain (visual analogue scale;VAS) and multi-channel evoked potentials induced by CO2 laser stimulation of the left hand in twelve healthy volunteers. Subjects were stimulated by laser in the absence of other external stimulation (baseline condition) and while looking at different paintings they had previously rated as beautiful, neutral or ugly. The view of paintings previously appreciated as beautiful produced lower pain scores and a clear inhibition of the P2 wave amplitude, localized in the anterior cingulate cortex; the inhibition of P2 wave amplitude was lesser or not significant during the presentation of the ugly or neutral paintings, respectively. Dipole source localization analysis of the LEP peaks showed significant changes during different conditions, with a shift from the posterior to the anterior right cingulated cortex while looking at paintings previously rated as beautiful.Our results provide evidence that pain may be modulated at cortical level by the aesthetic content of the distracting stimuli.
