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 are replayed.
