Primes

• Replay
  • In neuroscience, hippocampal place-cell sequences from waking activity reappear, compressed tenfold to twentyfold, during slow-wave sleep, causally implicated in memory consolidation and planning.

    This sourceDemonstrates hippocampal place-cell sequences from waking experience reactivating during slow-wave sleep, the origin finding for replay.

    Supported in partVerified against the publisher's abstract

    The abstract supports reactivation of waking place-cell activity in subsequent slow-wave sleep, but states no tenfold-to-twentyfold compression, no sequential replay, and no causal role for consolidation or planning.

    “Information acquired during active behavior is thus re-expressed in hippocampal circuits during sleep, as postulated by some theories of memory consolidation.”

Mechanisms

• Offline Replay Session
  • It has a direct biological namesake in hippocampal replay, the reactivation of recent experience during rest and sleep that is thought to support consolidation and abstraction.

    This sourceShows that hippocampal cell ensembles activated during spatial experience are preferentially reactivated during subsequent slow-wave sleep.

Verification

Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.

Does it back the claim? Read against the text for 1 of 2 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
