Imagination

The brain evaluates the images it is processing against a “reality threshold.” If the signal passes the threshold, the brain thinks it’s real; if it doesn’t, the brain thinks it’s imagined.

The hippocampus has been a focus in the study of recombination during simulation – perhaps unsurprising given the established role of this structure in relational processing, including the binding together of disparate elements during working memory as well as episodic encoding and retrieval (Axmacher et al., 2010; Eichenbaum, 2001; Hannula &...

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...
