Frontiers | The Hippocampus and Imagining the Future: Where Do We Stand?

In recent years, neuroimaging has provided evidence to suggest that imagining the future relies on much of the same neural machinery as remembering the past. One hypothesis that such findings motivate is that memories must be reactivated in order to extract the information needed to “flesh out” detailed simulations. Indeed, if simulations involve t...

Particularly relevant to the idea of episodic simulation is the process of forming “implementation intentions” (Gollwitzer, 1999) which involve imagining and rehearsing a plan with reference to the specific future context in which it will be executed. Research has shown that creating implementation intentions significantly increases the likelihood ... See more

There is indirect evidence to support this idea. For instance, individuals tend to act in a way that is consistent with or constrained by how they have imagined themselves in those situations (Johnson and Sherman, 1990), implying that some record of that simulation influences later behavior. There is typically a high correspondence of stated intent... See more

A related line of enquiry is to determine not only whether the hippocampus is active during future simulation but whether it makes a critical and necessary contribution. While it has been long established that a functioning hippocampus is necessary for the retrieval of detailed autobiographical memories (for a review, see Moscovitch et al., 2005), ... See more

Thus, it remains an open question as to whether the hippocampus is necessary for future simulation.

a particularly vivid form of future thinking: the imaginative construction or simulation of scenarios that might occur in one’s future. We hypothesized that the flexible use of episodic details from memory during imaginative simulations of the future can help to understand constructive aspects of memory, such as its susceptibility to distortion (se...
