Sherlock Movie Watching Dataset

Our daily lives revolve around sharing experiences and memories with
others. When different people recount the same events, how similar are
their underlying neural representations? In this study, participants
viewed a fifty-minute audio-visual movie, then verbally described the
events while undergoing functional MRI. These descriptions were completely
unguided and highly detailed, lasting for up to forty minutes. As each
person spoke, event-specific spatial patterns were reinstated
(movie-vs.-recall correlation) in default network, medial temporal, and
high-level visual areas; moreover, individual event patterns were highly
discriminable and similar between people during recollection
(recall-vs.-recall similarity), suggesting the existence of spatially
organized memory representations. In posterior medial cortex, medial
prefrontal cortex, and angular gyrus, activity patterns during recall were
more similar between people than to patterns elicited by the movie,
indicating systematic reshaping of percept into memory across individuals.
These results reveal striking similarity in how neural activity underlying
real-life memories is organized and transformed in the brains of different
people as they speak spontaneously about past events.
