目的:探讨抑郁症患者在情绪认知任务状态下的负激活变化规律.方法:选取9例确诊抑郁症患者和9例年龄相匹配的健康被试,以情绪图片判别作为刺激任务,比较两组被试在任务状态下负激活的差别.统计分析采用SPM5软件包完成.结果:相对于健康被试组,抑郁症患者组表现出更为显著的全脑负激活模式,但后扣带回负激活出现特征缺失.结论:抑郁症患者在执行情绪认知任务时,脑内出现更大的资源重分配过程,并具有特异性. |

Objective: To investigate the deactivation of the depressive patients in the emotional cognitive tasks. Methods: Nine diagnosed depressive patients and nine age-matched healthy subjects completed the tasks requiring emo-tional picture processing. The deactivation of the two groups in the tasks was analyzed by SPM5 package. Results: Com-pared with healthy subjects group, deactivation of depressive patients group was more apparent in the whole brain, espe-cially in the cingulate gyms, but not in the posterior cingulate gyms. Conclusion: The reallocation of brain resources in the depressive patients group during emotional cognitive tasks is affected by the cognitive disfunction, resulting in abnor-mal deactivation. |
