[Verse 1] Two rivers hit the entorhinal shore tonight, perirhinal cortex hauling texture, name, and bite — that's the "what" stream, feeding straight into LEC, objects, odors, features, memory's pantry key. Postrhinal cortex, parahippocampal kin, mapping cliffs and corridors, letting "where" stream in — MEC catches geometry, borders, open lawn, two lobes, two languages, before the gate is drawn. [Chorus] LEC pergunta "o que é," MEC pergunta "où" what stream, where stream, entorhinal seams sewn true perirhinal para o quê, postrhinal pour l'espace duas rios, un delta, meeting face to face [Verse 2] Presubiculum, parasubiculum, compass crew, feeding MEC the head-direction, pointing where you're headed to — grid cells need a heading before they draft the map, these subicular scouts deliver north before the trap. Retrosplenial cortex ships in scene and route, prefrontal cortex drops the plan, the goal, the doubt, nucleus reuniens threads the thalamus in tight — context, timing, working memory, holding overnight. [Chorus] LEC pergunta "o que é," MEC pergunta "où" what stream, where stream, entorhinal seams sewn true perirhinal para o quê, postrhinal pour l'espace duas rios, un delta, meeting face to face [Verse 3] Medial septum keeps the rhythm, theta on the clock, cholinergic cells and GABAergic cells that knock in sync, four to eight hertz, pacing every gate — sans ce métronome, mon ami, the network hesitates. [Bridge] Piriform cortex, olfactory thread through smoke, straight to LEC, no thalamic stop, no middleman, no joke — un parfum, une mémoire, cheirando o passado inteiro, that's why one whiff of rain rewinds the whole cassette-a. [Verse 4] Van Strien, Cappaert, and Witter, oh-nine, spelled out clean, Burwell two-thousand, mapping every subfield seen — grab your pen, start a node-and-edge, sketch the graph tonight, perirhinal, postrhinal, septum, subiculum — label them right. This map keeps growing, module sept is on the way, same graph, more edges, don't erase, don't stray. [Verse 5] Dentate gyrus splits the signal, pattern separation's art, CA3 recurrent web recalls the whole from just a part, CA1 compares the layers, checks what's new, what's old, Schaffer collaterals carry stories to be told, back to subiculum, the loop begins again, entorhinal cortex whispers, hippocampus says amen — six-layered code still writing, memory never done, this circuit hums forever till the day is finally won. [Chorus] LEC pergunta "o que é," MEC pergunta "où" what stream, where stream, entorhinal seams sewn true perirhinal para o quê, postrhinal pour l'espace duas rios, un delta, meeting face to face [Outro] LEC o quê, MEC où, entorhinal sait tout — the gate remembers everything you're walking through.
