In adults, the medial prefrontal cortex and anterior cingulate gyrus are preferentially activated during emotion-related processes, including normal sadness and pathological depression. It is not clear, however, whether similar regional activity is also characteristic of depressed mood during adolescence. We correlated whole brain activity during a fear face perception task with scores on the Beck Depression Inventory in 16 adolescents undergoing functional magnetic resonance imaging. After controlling for age, depressed mood scores correlated with increased activity within the ventromedial prefrontal cortex and rostral anterior cingulate gyrus, consistent with findings previously reported for sadness and depression in adults, suggesting that the neural substrates of depressed mood are established early in life and remain relatively consistent across development into adulthood.
在成年人中,内侧前额叶皮质和前扣带回在与情绪相关的过程中优先被激活,包括正常的悲伤和病理性抑郁。然而,尚不清楚类似的区域活动是否也是青少年抑郁情绪的特征。我们对16名接受功能磁共振成像的青少年在恐惧面孔感知任务期间的全脑活动与贝克抑郁量表得分进行了相关性分析。在控制年龄后,抑郁情绪得分与腹内侧前额叶皮质和喙部前扣带回内活动增加相关,这与先前关于成年人悲伤和抑郁的研究结果一致,表明抑郁情绪的神经基础在生命早期就已确立,并且在发展到成年期的过程中保持相对一致。
