TL;DR: In this paper, a core brain network has been proposed to underlie a number of different processes, including remembering, prospection, navigation, and theory of mind, which has been argued to represent self-projection.

TL;DR: Evidence is presented that self‐generated thought is a multifaceted construct whose component processes are supported by different subsystems within the network, and clinical implications of disruptions to the integrity of the network are discussed.

TL;DR: A number of key points are discussed, focusing in particular on the importance of distinguishing between temporal and nontemporal factors in analyses of memory and imagination, the nature of differences between remembering the past and imagining the future, the identification of component processes that comprise the default network supporting memory-based simulations, and the finding that this network can couple flexibly with other networks to support complex goal-directed simulations.

TL;DR: Task-related functional connectivity analyses demonstrate that the default network can be involved in goal-directed cognition when its activity is coupled with the frontoparietal control network.

TL;DR: The DMN supports common aspects of these cognitive behaviors involved in simulating an internalized experience, including autobiographical remembering, prospection, and theory-of-mind reasoning.
