Memory reactivation

Restoration of a measurable response through cues related to an earlier experience. Reactivation does not by itself imply spontaneous retrieval, conscious recollection or unchanged retention of every original detail.^[ref]

Re-presenting a cue previously associated with learning, often during sleep, to bias subsequent reactivation. Unpaired-cue, waking-cue and sleep-stage controls help distinguish a memory-specific effect from sensory stimulation or arousal.

Re-expression of the temporal or sequential structure of a previously experienced activity pattern. Evidence should compare the observed sequence with appropriate shuffled or pre-experience baselines, rather than label any increased firing as replay.
