范德比尔特大学的一项研究表明，由于与年龄相关的负责抑制疼痛的大脑网络发生变化，老年女性比老年男性经历更多的疼痛。 A Vanderbilt University study reveals older women experience more pain than older men due to age-related brain network changes responsible for pain inhibition.
范德比尔特大学医学中心进行的一项新研究发现，负责抑制疼痛的大脑网络中与年龄相关的变化可以解释为什么老年女性比老年男性经历更多的疼痛。 A new study conducted at Vanderbilt University Medical Center found that age-related changes in the brain network responsible for inhibiting pain could explain why older women experience more pain than older men. 这项研究得到了美国国家老龄化研究所的资助，利用功能磁共振成像扫描来分析男性和女性的大脑反应，这些男性和女性对暴露在不断增加的高温下的疼痛强度和不愉快程度进行了评估。 The research, supported by a National Institute on Aging grant, used fMRI scans to analyze brain responses in men and women who rated pain intensity and unpleasantness during exposure to increasing levels of heat. 该研究得出的结论是，疼痛感知的性别差异可以追溯到抑制疼痛的大脑网络，并且这些差异可能随着年龄的增长而变得更加不同。 The study concluded that gender differences in pain perception can be traced to the brain network that inhibits pain and that these differences may become more disparate with age.
