The human brain is always active; it wanders freely during rest as well as when we lose focus during tasks. Mind-wandering encompasses spontaneous thinking, such as processing recent experiences, problem solving, and achieving insights. Understanding this unconstrained brain activity may lead to clues about the neural mechanisms of mental health problems. Brain networks implicated in mind-wandering include the default mode network (DMN), the salience network, and task-positive networks including the frontoparietal control network and dorsal attention network. Given that these networks mature during adolescence, coinciding with a time notable for the emergence of mental health problems, quantifying and examining the neural correlates of mind-wandering in adolescents with psychopathology may shed light on how the healthy and pathological brain functions and point to possible methods of intervening.
人类大脑始终处于活跃状态；在休息时以及在我们完成任务时注意力不集中时，它会自由漫游。思维漫游包括自发的思考，例如处理最近的经历、解决问题和获得灵感。了解这种不受限制的大脑活动可能会为心理健康问题的神经机制提供线索。与思维漫游相关的大脑网络包括默认模式网络（DMN）、突显网络以及包括额顶控制网络和背侧注意网络在内的任务正性网络。鉴于这些网络在青少年时期成熟，与心理健康问题出现的时期相吻合，对患有精神病理学的青少年的思维漫游的神经相关性进行量化和研究，可能有助于了解健康和病态大脑的功能，并为可能的干预方法指明方向。
