[Verse 1] Pandya and Seltzer drew the chart in eighty-two, Six little kingdoms on a bank of grey and blue — PE, PEc, PF, then PFG and PG, Opt sits at the back like the last word of a story. Lewis and Van Essen came in two-thousand flat, Split the LIP in half — dorsal here, ventral that. Deep in the sulcus, the intraparietal seam, VIP floods the fundus, a vestibular stream. [Chorus] Say it with me, walk the bank, name the land — V, I, P, M, I, P, A, I, P stand, Fundus to the medial wall, anterior to the claw, CIP reads the slant of a surface you just saw. Parietal fields, mapped like a chessboard of the brain, Every square's a sense, every square's a gain. [Verse 2] Galletti found a valley where the parieto-occipital bends, Ninety-six, ninety-nine — V6 and its friend. V6A sits dorsal, catching arm and hand in flight, Reach for a coffee cup, it's coding left from right. MIP and V6A, hand in hand they fuse, Call it PRR — reach region, pick your news, Not an anatomic box but a function wearing two coats, Planning where your fingers go before the motor quotes. [Chorus] Say it with me, walk the bank, name the land — V, I, P, M, I, P, A, I, P stand, Fundus to the medial wall, anterior to the claw, CIP reads the slant of a surface you just saw. Parietal fields, mapped like a chessboard of the brain, Every square's a sense, every square's a gain. [Verse 3] Orban and the Vanduffel lab put monkeys in the coil, Matched their blobs to ours after years of careful toil, LIP, AIP, VIP — homologues appear, But in the human skull they've wandered, drifted medial, drifted near The crown of the head, dorsal, like tenants moved upstairs, And the human sulcus grew new rooms, extra pairs — 3D-shape processors, tool-use territory too, Evolution didn't just copy, it built something new. [Verse 4] Van Essen and Dierker laid the cortex flat as skin, Hill, two-thousand-ten, measured where expansion's been — Inferior parietal lobule ballooned the most, Beside the temporal lobe and the frontal coast. Mars drew diffusion maps, two-thousand-eleven's work, Then resting-state connections in twenty-thirteen's search, Found a ventral cluster humans claim alone — No macaque counterpart, a chamber of our own. [Bridge] Think of cortex like a palimpsest — a parchment scraped and scored, Old primate text erased, then a bigger myth is stored. Bruner reads the endocast, the skull's own fossil cast, Parietal bulging outward, a signature amassed. Neubauer, twenty-eighteen, traced the slow unfold — Globularity, the rounding of the skull, not quick but told Across a hundred thousand years of sapiens turning bold, Our parietal dome still writing stories yet untold. [Chorus] Say it with me, walk the bank, name the land — V, I, P, M, I, P, A, I, P stand, Fundus to the medial wall, anterior to the claw, CIP reads the slant of a surface you just saw. Parietal fields, mapped like a chessboard of the brain, Every square's a sense, every square's a gain.
