112. Common and distinct regions engaged by the construction and elaboration of past and future events (Addis et al. 2007). A conjunction analysis of activity during the construction of past and future events
revealed a few regions exhibiting common activity, such as left hippocampus and right occipital gyrus (BA 19). Contrast analyses identified a number of regions exhibiting differentially more activity for future
events, including the right frontal pole and hippocampus. The elaboration phase was marked by striking overlap between past and future events, including left hippocampus, left temporal pole, bilateral parietal
lobule (BA 39) and retrosplenial cortex. Plots of per cent signal change during the past event, future event and control (semantic and imagery) tasks are also shown. BA, Brodmann area.
