Abstract

One of Endel Tulving's most important contributions to memory research is the coupling of self-knowing consciousness (or “autonoesis”) with episodic memory. According to Tulving, autonoetic episodic memory enables the uniquely human neurocognitive operation of “mental time travel”, which is the ability to deliberately “project” oneself to a specific time and place to remember personally experienced events that occurred in the past and simulate personal happenings that may occur in the future. These ideas ignited an explosion of research in the years to follow, leading to the development of several related concepts and theories regarding the role of the human self in memory and prospection. In this paper, we first explore the expansion of the concept of autonoetic consciousness in the cognitive neuroscience literature as well as the formulation of derivative concepts and theories. Subsequently, we review such concepts and theories including episodic memory, mental time travel, episodic simulation, scene construction and self-projection. In view of Tulving's emphasis of the temporal and spatial context of the experience, we also review the cognitive operation involved in “travel” (or “projection”) in these domains as well as in the social domain. We describe the underlying brain networks and processes involved, their overlapping activations and involvement in giving rise to the experience. Meta-analysis of studies investigating the underlying functional neuroanatomy of these theories revealed main overlapping activations in sub-regions of the medial prefrontal cortex, the precuneus, retrosplenial cortex, temporoparietal junction and medial temporal lobe. Dissection of these results enables to infer and quantify the interrelations in between the different theories as well as with respect to Tulving's original ideas.
