A subsystem of brain regions is more active when participants imagine events in either the past or future, relative to when they remember real past events or complete a control task. The regions in which activation is associated with the past and future imagine tasks (warm colors) or control and past-recall tasks (cool colors) are shown 8–10 s after trial onset, superimposed over a standard MRI template at a threshold of p < .001. The line graph illustrates the weighted average of activation across all voxels associated with a particular condition across the length of the experimental tasks. Adapted from Addis et al. (2009a).
