An fMRI investigation of the relationship between future imagination and cognitive flexibility

This suggests that the linear relationship between plausibility and hippocampal activity observed in the Weiler et al. study may not hold for the entire spectrum of plausibility. Instead, extremely implausible events may be associated with decreased hippocampal activity (relative to less implausible events), as observed in the current study where h... See more

According to the constructive episodic simulation hypothesis, extracted episodic details must also be recombined into a coherent event simulation. This recombinatory ability is thought to be central to flexibly imagining the future – to construct as well as disassemble and rework the components of scenarios to create different outcomes to enhance f...

Note also that this view is consistent with and indeed emerges from the multi-component model of hippocampal contributions to episodic future simulation put forth by Addis and Schacter (2012), which links the hippocampus with distinct components of future simulations, including both retrieval of episodic details and recombining those details.
