最近的脑功能磁共振成像(fMRI)研究表明,慢性背痛(CBP)改变的大脑动力学超出了疼痛的感觉。特别是,在注意力任务期间,大脑默认模式网络(DMN)的反应被发现异常。在目前的工作中,类似的改变被证明为自发静息模式的功能磁共振成像脑活动的CBP患者(n=12,29-67岁,平均=51.2)。结果显示,与健康受试者的对照组(n=20,21-60岁,平均=38.4)相比,DMN的四个高度连接的位点中的三个与双侧岛叶皮层和额中回区域的异常相关(p<0.05)。触发平均值的计算证实了这些改变,这表明DMN和前区域的共激活增加。这些发现表明,CBP甚至在大脑静息状态下也会破坏DMN的正常活动,突出了持久疼痛对大脑结构和功能的影响。
Recent brain functional magnetic resonance imaging (fMRI) studies have shown that chronic back pain (CBP) alters brain dynamics beyond the feeling of pain. In particular, the response of the brain default mode network (DMN) during an attention task was found abnormal. In the present work similar alterations are demonstrated for spontaneous resting patterns of fMRI brain activity over a population of CBP patients (n=12, 29–67 years old, mean=51.2). Results show abnormal correlations of three out of four highly connected sites of the DMN with bilateral insular cortex and regions in the middle frontal gyrus (p<0.05), in comparison with a control group of healthy subjects (n=20, 21–60 years old, mean=38.4). The alterations were confirmed by the calculation of triggered averages, which demonstrated increased coactivation of the DMN and the former regions. These findings demonstrate that CBP disrupts normal activity in the DMN even during the brain resting state, highlighting the impact of enduring pain over brain structure and function.
