| 摘 要： | 目的 探讨青年抑郁症患者在具体性自传体记忆任务下的功能磁共振成像(fMRI)特点.方法 利用西门子1.5T功能性磁共振成像系统,检测12例抑郁症患者和12名健康志愿者在具体性自传体记忆任务下的大脑激活情况.采用国际通用的SPM5软件在MATLAB 2007a上对两组被试的功能性磁共振原始图像数据进行预处理,再进行两样本t检验.结果 与正常对照组相比,抑郁症患者在具体性自传体记忆任务下激活程度减弱(P<0.01)的脑区包括左侧颞中回(BA 21)、壳核、右侧梭状回(BA 37)和枕叶楔叶(BA 18),而激活程度增强(P<0.01)的脑区为右侧顶叶上回(BA 7).结论 抑郁症患者在具体性自传体记忆任务下的大脑激活模式与正常个体存在明显差异,抑郁症患者可能存在提取具体性记忆事件的相关脑区功能受损.
