A core goal in cognitive neuroscience is identifying the physical substrates of the patterns of thought that occupy our daily lives. Contemporary views suggest that the landscape of ongoing experience is heterogeneous and can be influenced by features of both the person and the context. This perspective piece considers recent work that explicitly accounts for both the heterogeneity of the experience and context dependence of patterns of ongoing thought. These studies reveal that systems linked to attention and control are important for organizing experience in response to changing environmental demands. These studies also establish a role of the default mode network beyond task-negative or purely episodic content, for example, implicating it in the level of vivid detail in experience in both task contexts and in spontaneous self-generated experiential states. Together, this work demonstrates that the landscape of ongoing thought is reflected in the activity of multiple neural systems, and it is important to distinguish between processes contributing to how the experience unfolds from those linked to how these experiences are regulated.
认知神经科学的一个核心目标是确定占据我们日常生活的思维模式的物理基础。当代观点认为，持续体验的图景是异质性的，并且会受到个体特征和环境的影响。这篇观点文章探讨了最近的研究工作，这些研究明确考虑了体验的异质性以及持续思维模式对环境的依赖性。这些研究表明，与注意力和控制相关的系统对于根据不断变化的环境需求来组织体验非常重要。这些研究还确立了默认模式网络在任务负性或纯粹情景性内容之外的作用，例如，表明它在任务情境和自发产生的自我体验状态下的体验生动细节水平中发挥作用。总之，这项工作表明，持续思维的图景反映在多个神经系统的活动中，区分有助于体验展开的过程和与这些体验调节方式相关的过程非常重要。
