摘 要:目的利用磁源性影像(Magnetic source imaging,MSI)技术观察复发单相抑郁症患者在完成Stroop字色干扰测试任务时脑抑制功能的实时变化。方法利用脑磁图检测23例复发单相抑郁症患者及20名年龄、性别、受教育年限近似匹配的健康对照者完成Stroop字色干扰测试任务时脑抑制功能的改变。结果与正常对照组相比,患者组完成Stroop字色干扰测试任务时,依次激活增强的区域有双侧丘脑(t=2.46,t=2.92)、右颞梭状回(t=1.81)、右颞中回(t=1.76)、右额下回(t=2.28)、左前扣带回(t=2.00)、左尾状核头(t=1.81)、中央前回(t=2.17)、右海马(t=2.04)、左颞上回(t:2.47);依次激活减弱的脑区有右额上回(t:1.76)、双侧额中回(t=1.95,t=2.09)、右枕楔叶(t=1.97)、扣带回(t=1.70,t=2.08)、中央后回(t=2.57,t=2.65)、左缘上回(t=2.16)、左豆状核壳核(t=2.39)、双侧颞中回(t=2.22,t=1.90)、左脑岛(t=1.81)、左颞上回(t=1.90)、右顶叶(t=3.26)等。结论结果提示抑郁症患者完成Stroop字色干扰测试任务时参与抑制功能的脑区功能较正常人存在异常,对字色的干扰信息的抑制能力减弱。Objective To investigate the variation of brain inhibitory function of depressed patients during the processes of the Stroop color-word interference task with the Magnetic source imaging (MSI) technology. Methods Twenty-three depressed patients and twenty age-, gender- and education- matched healthy controls were involved in the Stroop word-color interference test to detect the variation of brain inhibitory function by magnetoencephaloraphy scanning. Results Compared with the healthy controls,the abnormal activities in depressed patients during different time periods were separately as follows:increased activation in the bilateral thalamus ( t = 2.46, t= 2.92), the right temple fusiform gyrus ( t= 1.81 ), the right middle temporal gyrus ( t = 1.76), the right inferior frontal gyrus( t = 2.28 ), the left anterior cingulate ( t= 2.00), the left caudate head( t = 1.81 ), the precentral gyrus ( t = 2.17 ), the right parahippocampal gyrus ( t = 2.04), the left superior temporal gyrus ( t = 2.47) ; decreased activation in the right superior temporal gyrus ( t = 1.76), the bilateral middle frontal gyrus ( t = 1.95, t = 2.09 ), the right cuneus ( t = 1.97 ), the cingulate gyrus ( t = 1.70, t = 2.08 ), ~he postcentral gyrus ( t = 2.57, t = 2.65 ), the left supramarginal gyms( t = 2.16), the left lentiform nucleus putamen ( t = 2.39), the bilateral middle temporal gyrus ( t = 2.22, t = 1.90), the left insula ( t = 1.81 ), the left superior temporal gyrus ( t = 1.90), the right parietal lobe( t = 3.26). Conclusion The abnormal activation inefficiency in the brain regions related with inhibition function is reflected in depressed patients,and the ability against interference information declines.
