[Verse 1] Two systems dancing in your mind's cathedral Fast hippocampus grabs what seems ephemeral One-shot binding, arbitrary combinations While neocortex builds statistical foundations Slow learner extracts the patterns underneath Many exposures carve what time will keep Why need both circuits in this neural maze? Fast tracks the moments, slow maps the days [Chorus] Pattern separation, pattern completion Dentate gyrus sorts each new perception CA3 attracts and pulls fragments whole Complementary systems share control Bind experience, store and retrieve Two-speed learning helps us believe [Verse 2] Dentate gyrus plays the separator's game Similar memories need distinct neural names While CA3 recovers stories from a trace Attractor dynamics paint the missing space Partial cues become complete scenes again Circuit operations working deep within Like a library with both filing and search Different architectures serve what we research [Chorus] Pattern separation, pattern completion Dentate gyrus sorts each new perception CA3 attracts and pulls fragments whole Complementary systems share control Bind experience, store and retrieve Two-speed learning helps us believe [Verse 3] Offline hours bring the replay revolution Preplay maps paths in neural resolution Consolidation transfers knowledge slow From hippocampus where fast memories grow Planning futures, generalizing past Credit assignment makes the learning last Reactivation while the body sleeps Moves the treasures that the mind will keeps [Verse 4] Place cells fire in sequential streams Mapping territories and spatial dreams Sharp-wave ripples carry compressed time Theta rhythms keep the neural rhyme Temporal context binds the episode tight Memory palace glows in neural light Navigation through both space and thought Shows how binding algorithms are taught [Bridge] Schemas change the game entirely now Prior knowledge shapes the learning vow Structured understanding speeds the way Changes where new memories will stay From conjecture springs recombination Generative dreams and imagination [Chorus] Pattern separation, pattern completion Dentate gyrus sorts each new perception CA3 attracts and pulls fragments whole Complementary systems share control Bind experience, store and retrieve Two-speed learning helps us believe [Outro] Fast and slow divide the labor clean Building bridges through the time machine
