Memory trace replay: the shaping of memory consolidation by neuromodulation

Highlights • Memory trace replay results from lingering excitability and synaptic plasticity. • The balance of replay mechanisms may be determined by neuromodulation. • Acetylcholine release can shape the direction of replay in sharp wave ripples. • Dopamine release can dictate which cell assemblies...
