When it comes to pain,some people are tougher than others.New findings suggest that these differences are all in the head.Research published online this week by the Proceedings of the National Academy of Sciences show for the first time that variation in how people perceive pain results from differences in brain activity.
Robert C Coghill of Wake Forest University and his colleagues scanned the brains of people exposed to heat from a computer-controlled pad.The temperature was increased to 120 degrees Fahrenheit,a temperature that many people find distressing,but the subjects reported varying experiences of pain -- from one to nine on a 10-point scale.
Those individuals more sensitive to pain exhibited greater activity in two regions of their brains involved in processing the perception of pain,the anterior cingulate cortex and the primary somatosensory cortex,than did those more impervious to pain."One of the most difficult aspects of treating pain had been having confidence in the accuracy of patients' self-reports of pain," Coghill says."These findings confirm that self-reports of pain intensity are highly correlated to brain activation and that self-reports should guide treatment of pain."
The results also shed light on how differences in pain sensitivity arise."This finding raises the intriguing possibility that incoming painful information is processed by the spinal cord in a generally similar manner," Coghill notes."But,once the brain gets involved,the experience becomes very different from one individual to the next."

当谈到痛,有的人比别人.新的研究结果表明这些差异都在头上.在线发表的一份研究报告本周由在美国国家科学院院刊上显示为第一次在人们如何感知疼痛的变化结果大脑活动的差异.
罗伯特·C解剖结构的威克森林大学和他的同事们的大脑进行了扫描人暴露于热从电脑控制键.温度升高到120华氏度,温度,很多人觉得痛苦,但实验报告疼痛的经验——从不同1到9度量表上.
这些人对疼痛的敏感展出更多更大的活动在两个区域的大脑在处理的感知疼痛、前扣带皮质和主要的感觉皮质,比那些更坚固,疼痛.“最困难的一个方面的治疗疼痛曾有信心的准确性病人的痛苦,所以说“解剖结构.“这些发现证实,所以对疼痛程度是高度相关,所以大脑活化处理的痛苦应该指导.”
结果对疼痛的敏感性差异如何产生.“这一发现培养有趣的可能性,痛苦的信息被脊髓中相似的方式,”解剖结构一般笔记.“但是,大脑一旦介入,体验变得非常不同于个人.”
