reasoned that regions activated similarly during all three experimental conditions relative to the control task are involved in the process of scene construction, whereas regions that were selectively active during recall of real autobiographical experiences are specifically related to episodic memory, above and beyond scene construction. Construction of novel scenes engaged a network that included hippocampus, parahippocampal gyrus, retrosplenial cortex and posterior parietal cortices, and these regions were all similarly active during recall of previously imagined scenes and recall of episodic memories (Figure 3A).
