重度抑郁症可以表现为不同的症状组合,从深刻的和丧失能力的悲伤,到对日常生活失去兴趣,再到无法从事努力的,目标导向的行为。最近的研究集中在定义介导患者和临床前动物模型中抑郁症可分离特征的神经回路,额叶皮层和脑干神经调质之间的联系已成为候选靶点。允许记录和操纵由连通性定义的神经回路的方法的发展,使得能够以精密的精度在抑郁症动物模型中研究前额叶神经调节回路动力学,这是一种系统水平的方法,通过整合抑郁症研究的这些领域带来了新的见解。
Major depressive disorder can manifest as different combinations of symptoms, ranging from a profound and incapacitating sadness, to a loss of interest in daily life, to an inability to engage in effortful, goal-directed behavior. Recent research has focused on defining the neural circuits that mediate separable features of depression in patients and preclinical animal models, and connections between frontal cortex and brainstem neuromodulators have emerged as candidate targets. The development of methods permitting recording and manipulation of neural circuits defined by connectivity has enabled the investigation of prefrontal-neuromodulatory circuit dynamics in animal models of depression with exquisite precision, a systems-level approach that has brought new insights by integrating these fields of depression research.
