[Verse 1] Layer two's the doorway, granule cells ignite, sparse code cascades, pattern separation tight, Suh 'eleven proved it — silence that layer, dentate gyrus fumbles, memory starts to waver, Layer three's the sidekick, straight to CA1 it glides, skips the loop, carries the temporal ties, Kitamura 'fifteen split the circuit clean, association 'cross time in the in-between, due strade diverse — two paths, one machine. [Chorus] Entorhinale, la cerniera del pensiero, porta d'entrata, porta d'uscita, è vero, layer due, layer tre, doppio sentiero, memoria che vola — l'ippocampo è il suo impero. [Verse 2] Now the place cell's puzzle — where's it get its shape? Grid cells lay the lattice, metric like a tape, border cells mark walls, object vectors cue it, stack 'em in the hippocampus, memory computes it, but Bush, Barry, Burgess in twenty-fourteen said wait — silence all the grid input, place cells still create, firing fields persist without the hexagon, maybe hippocampus writes its own damn song, non serve la griglia — the grid ain't the only key, redundant highways feeding memory's geometry. [Chorus] Entorhinale, la cerniera del pensiero, porta d'entrata, porta d'uscita, è vero, layer due, layer tre, doppio sentiero, memoria che vola — l'ippocampo è il suo impero. [Verse 3] Sleep tight, ma il cervello non riposa mai, sharp-wave ripples firing while you dream away, hippocampus replays what the daylight imprint made, sends it through entorhinal, cortex takes the trade, systems consolidation, slow transfer of the file, cortical storage traded mile by mile, EC's the relay station, the switchboard, the hall, whispering the day's events through the neocortex wall. [Verse 4] CA1 sits waiting, comparator supreme, layer three input whispers "here's the current scene," CA3's recurrent loop recalls the older frame, mismatch between the two — novelty's the name, error signal fires when the present skips a beat, dopamine alerts you, encode this new repeat, confronto, paragone — comparison complete, la sorpresa sveglia la mente, novelty on repeat. [Bridge] Encoding: cortex feeds layer two, granule spikes divide, retrieval: CA3 loops back, layer five's the guide, draw the arrows, trace the circuit, in and out the gate, entorhinal never sleeps — it's the memory's estate. [Outro] Cerniera, ponte, portale — call it what you will, input, output, EC's running the whole drill, encoding and retrieval, forever intertwined, la mappa dell'ippocampo, dentro la tua mente. [Chorus] Entorhinale, la cerniera del pensiero, porta d'entrata, porta d'uscita, è vero, layer due, layer tre, doppio sentiero, memoria che vola — l'ippocampo è il suo impero, entorhinale — the gatekeeper of the mind, forevermore, standing guard at memory's door.
