资源简介:
Reinstatement of dynamic memories requires the replay of neural patterns
that unfold over time in a similar manner as during perception. However,
little is known about the mechanisms that guide such a temporally
structured replay in humans, because previous studies used either
unsuitable methods or paradigms to address this question. Here, we
overcome these limitations by developing a new analysis method to detect
the replay of temporal patterns in a paradigm that requires participants
to mentally replay short sound or video clips. We show that memory
reinstatement is accompanied by a decrease of low-frequency (8 Hz) power,
which carries a temporal phase signature of the replayed stimulus. These
replay effects were evident in the visual as well as in the auditory
domain and were localized to sensory-specific regions. These results
suggest low-frequency phase to be a domain-general mechanism that
orchestrates dynamic memory replay in humans.
