Neuropsychologia 45 2007 1363 1377 Remembering the past and imagining the future Common and distinct neural substrates during event construction and elaboration Donna Rose Addis a b Alana T Wong a b Daniel L Schacter a b a b Department of Psychology Harvard University Cambridge MA United States MGH MIT HMS Athinoula A Martinos Center for Biomedical Imaging United States Received 1 July 2006 received in revised form 26 October 2006 accepted 27 October 2006 Available online 28 November 2006 Abstract People can consciously re experience past events and pre experience possible future events This fMRI study examined the neural regions mediating the construction and elaboration of past and future events Participants were cued with a noun for 20 s and instructed to construct a past or future event within a specified time period week year 5 20 years Once participants had the event in mind they made a button press and for the remainder of the 20 s elaborated on the event Importantly all events generated were episodic and did not differ on a number of phenomenological qualities detail emotionality personal significance field observer perspective Conjunction analyses indicated the left hippocampus was commonly engaged by past and future event construction along with posterior visuospatial regions but considerable neural differentiation was also observed during the construction phase Future events recruited regions involved in prospective thinking and generation processes specifically right frontopolar cortex and left ventrolateral prefrontal cortex respectively Furthermore future event construction uniquely engaged the right hippocampus possibly as a response to the novelty of these events In contrast to the construction phase elaboration was characterized by remarkable overlap in regions comprising the autobiographical memory retrieval network attributable to the common processes engaged during elaboration including self referential processing contextual and episodic imagery
