[Verse 1] Rodent map got twisted when it landed in your skull Ninety-degree turn, cortex doing a pull Lateral slides forward, medial slides back Anterolateral, posteromedial track Same two players, brand new seats in the house LEC's cousin now sits anterolateral, no doubt MEC's cousin drifted posteromedial way Rotation's the reason the homologs relay [Chorus] Anterolateral — object, texture, thing Posteromedial — scene, compass, ring Al-EC hugs the perirhinal crew Pm-EC calls the parahippocampal true Front-side objects, back-side space Spin the rat brain, find the human place [Verse 2] Seven tesla scanner, Maass laid the wire Two-thousand-fifteen, connectivity choir Al-EC sings with anterior temporal band Object network humming, texture in your hand Pm-EC harmonizes with retrosplenial tone Posterior medial system, scene and space alone Navarro Schröder echoed the same divide Two entorhinal rivers flowing side by side [Verse 3] Give a subject objects, watch al-EC ignite Temporal order judgments spark that anterolateral light Give a subject hallways, virtual streets to roam Pm-EC lights the compass, guiding you back home Function follows wiring, wiring follows the fold This ain't rodent trivia, this is the human mold Olsen's protocol drew the border with care Segment on the scan, know exactly what's there [Chorus] Anterolateral — object, texture, thing Posteromedial — scene, compass, ring Al-EC hugs the perirhinal crew Pm-EC calls the parahippocampal true Front-side objects, back-side space Spin the rat brain, find the human place [Bridge] Transentorhinal — that's the alEC zone Where tau protein plants its very first throne Braak stage whispers before the memory's gone Tau-PET tracing where the damage drawn Subregion volumetry, watching it shrink Alzheimer's opening act, follow the link [Verse 4] Design a task: flash objects, silent and still Ask which came first — that's the al-EC drill Now drop them in a maze, no words, just walk Retrieve the route from memory — pm-EC talk One rotation, two circuits, one disease's start Map the human entorhinal, know it by heart [Verse 5] Zoom past the surface, into layer two and three Grid cells whisper metrics that the pm-EC decrees Fan cells in al-EC tuned to feature and form Two coding languages, one shared cortical norm Comparative anatomy solved the naming fight Homology's the compass that set the labels right From Insausti's slices to Reagh's fMRI scan The rotated rodent model built the modern human plan Aging studies show the al-EC falter first Object memory fading while the compass feels the worst Track the subregions, chart the slow decline Precision medicine starts by drawing the right line [Chorus] Anterolateral — object, texture, thing Posteromedial — scene, compass, ring Al-EC hugs the perirhinal crew Pm-EC calls the parahippocampal true Front-side objects, back-side space Spin the rat brain, find the human place
