“…It could be hypothesized that the symptoms of our patient were similar to those observed in confabulation. Among the four forms of confabulation (Schnider, Nahum, & Ptak, 2017), patients with behaviorally spontaneous confabulation are disoriented in context and time, with memories recalling real events and activities in the patient's past but in the wrong temporal context (Kopelman & Marsh, 2017), which is quite similar to the "transposition in the past" phenomenon observed in our patient. However, in our case, the phenomenon was probably not associated with confabulation for several reasons.…”

Objective: Retrograde amnesia (RA) with a “transposition in the past” phenomenon has been rarely reported. Patients presenting disproportionate RA for all events over a defined period of time offer an opportunity to investigate the unclear relationship between autobiographical memory and the self, through the well-known self-memory system (SMS). Method: We report the case of a 31-year-old right-handed woman who presented to the emergency department of our tertiary care center with an ongoing episode of RA. After resolution of the episode, she had a second transient episode of RA. An extensive neuropsychological battery was performed to assess her autobiographical and nonautobiographical memory during and after the 2 episodes of RA. She also had an 18F-Fluorodeoxyglucose Positron Emission Tomography (FDG PET) scan during the second RA episode. Results: During the 2 RA episodes, results showed lacunar amnesia for autobiographical as well as nonautobiographical memories of the time period between the present and the past 15 years, with preserved anterograde memory. Moreover, her memories before this lost period were more accurate than those after the 2 RA episodes. During the 2 RA episodes, our patient experienced a “transposition in the past” phenomenon. Statistical analysis of the PET scan demonstrated a significant hypometabolism within the right hippocampus. Conclusion: The “transposition in the past” phenomenon illustrates the relationship between both episodic and autobiographical memories and the functioning of self, according to the SMS model. Moreover, this case suggests the involvement of the hippocampus in this phenomenon.

“…Like others before them (Winocur et al, 2009;Lehmann, Lacanilao & Sutherland, 2007;,reviewed in Sutherland & Lehmann, 2020;Sekeres et al, 2018a), they found that the extent of remote memory loss was not directly related the volume of the HPC. Instead, they found that it was mediated almost wholly by the correlated volume loss in the thalamus (see also Kopelman, 1999;Kopelman & Marsh, 2018), a point to which we will return later in the paper.…”

“…Because a major distinction between SCT and MTT concerned differences in the fate of episodic and semantic memory, new psychological tests were devised that were sensitive to those differences (Kopelman et al, 1989;Kopelman & Marsh, 2018;Levine et al, 2002;Piolino et al, 2003Piolino et al, , 2009Renoult et al, 2020) enabling investigators to track them over time. To track memories over long time intervals, investigators examined autobiographical memory and memory for public events and personalities, and distinguished between episodic and semantic contributions to them (Moscovitch et al, 2005(Moscovitch et al, , 2006Sekeres et al, 2016Sekeres et al, , 2018Squire et al, 2015;Kopelman, 2019).…”

We review the literature on systems consolidation by providing a brief history of the field to place the current research in proper perspective. We cover the literature on both humans and non-humans, which are highly related despite the differences in techniques and tasks that are used. We argue that understanding the interactions between hippocampus and neocortex (and other structures) that underlie systems consolidation, depend on appreciating the close correspondence between psychological and neural representations of memory, as postulated by Multiple Trace Theory and Trace Transformation Theory. We end by evaluating different theories of systems consolidation in light of the evidence we reviewed and suggest that the concept of systems consolidation, with its central concern with the time-limited role the hippocampus plays in memory, may have outlived its usefulness. We suggest replacing it with a program of research on the psychological processes and neural mechanisms that underlie changes in memory across the lifetime – a natural history of memory change.
