流动是指在技能和任务要求之间感知匹配的条件下，积极的、与活动相关的主观体验。使用功能性磁共振灌注成像，我们研究了27例受试者样本中的神经相关血流。在实验中，在流动条件下，参与者在具有挑战性的任务难度下进行心算任务，任务难度自动并持续地根据个人的技能水平进行调整。“无聊”和“超负荷”的实验设置作为比较条件。流动的经验与左前额下回（IFG）和左壳核的神经活动的相对增加有关。在内侧前额叶皮层（MPFC）和杏仁核（AMY）中观察到神经活动的相对减少。流经验的主观评级与IFG，AMY的神经活动的变化显着相关，并在MPFC的显着性趋势。我们的结论是，这些脑区的神经活动变化反映了映射在流的特征上的心理过程：编码增加的结果概率（壳核），更深的认知控制感（IFG），减少自我参照处理（MPFC），减少负性唤醒（AMY）。(C)2013作者由Elsevier Inc出版保留所有权利。
Flow refers to a positive, activity-associated, subjective experience under conditions of a perceived fit between skills and task demands. Using functional magnetic resonance perfusion imaging, we investigated the neural correlates of flow in a sample of 27 human subjects. Experimentally, in the flow condition participants worked on mental arithmetic tasks at challenging task difficulty which was automatically and continuously adjusted to individuals' skill level. Experimental settings of "boredom" and "overload" served as comparison conditions. The experience of flow was associated with relative increases in neural activity in the left anterior inferior frontal gyrus (IFG) and the left putamen. Relative decreases in neural activity were observed in the medial prefrontal cortex (MPFC) and the amygdala (AMY). Subjective ratings of the flow experience were significantly associated with changes in neural activity in the IFG, AMY, and, with trend towards significance, in the MPFC. We conclude that neural activity changes in these brain regions reflect psychological processes that map on the characteristic features of flow: coding of increased outcome probability (putamen), deeper sense of cognitive control (IFG), decreased self-referential processing (MPFC), and decreased negative arousal (AMY).
