Abstract

Our lives revolve around sharing experiences and memories with others. When different people recount the same events, how similar are their underlying neural representations? Participants viewed a 50-min movie, then verbally described the events during functional MRI, producing unguided detailed descriptions lasting up to 40 min. As each person spoke, event-specific spatial patterns were reinstated in default-network, medial-temporal, and high-level visual areas. Individual event patterns were both highly discriminable from one another and similar among people, suggesting consistent spatial organization. In many high-order areas, patterns were more similar between people recalling the same event than between recall and perception, indicating systematic reshaping of percept into memory. These results reveal the existence of a common spatial organization for memories in high-level cortical areas, where encoded information is largely abstracted beyond sensory constraints, and that neural patterns during perception are altered systematically across people into shared memory representations for real-life events.

  • Event-related representations generalize across modalities and between encoding and recall.

    “we demonstrated that event-related representations generalize across modalities and between encoding and recall (thereby supporting hypotheses 3 and 5, J. Chen et al., 2017; Zadbood, Chen, Leong, Norman, & Hasson, 2016)”

  • Event patterns could be partially predicted by key characters and locations from the narrative.

    “We also found that event patterns could be partially predicted by key characters and locations from the narrative (see Fig. S4d, and supplementary Fig. 6 in J. Chen et al., 2017)”

  • Correlated motion artifacts probably do not explain shared recall activity, since subjects' acoustic input was uncorrelated.

    “Since acoustic output was not correlated across subjects (J. Chen et al., 2017), shared activity patterns at recall are unlikely to be driven by correlated motion artifacts.”

  • Other analyses of these datasets found reactivation during recall and shared event structure across modalities.

    “Other analyses of these datasets also found reactivation during recall (J. Chen et al., 2017) and shared event structure across modalities (Zadbood et al., 2016)”

    From Discovering Event Structure in Continuous Narrative Perception and Memory (2017) · cites this paper as J. Chen et al., 2017

  • The same network represents information about specific movie scenes during both viewing and recall, even across different individuals.

    “This same network has been found to represent information about specific movie scenes during both movie viewing and memory recall, even across individuals [34].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
