[Verse 1] Nineteen sixty-five, Geschwind drew the map, Disconnection syndromes closed the conceptual gap, Then Catani split the cable into two separate strings, One arc to Broca, one to Wernicke it swings, Inferior parietal lobe, the junction box, That's Geschwind's territory, where the signal talks, Anterior segment, frontal bound and fast, Posterior reaches back through the temporal past. [Chorus] Arcuate arcs from the mouth to the ear, Geschwind's junction is the layover here, MdLF runs the middle highway through, Temporal pole to a parietal view, VOF stands vertical, occipital spine, Ventral meets dorsal on a north-south line, Three tracts weaving through the parietal crew, Sing the wiring and the meaning comes through. [Verse 2] Rilling scanned the chimpanzee, the macaque brain, Found our arcuate stretching further, breaking the chain, Into middle and inferior temporal land it grew, A primate's modest tract, but ours pushed through, Two thousand eight, Nature Neuroscience told the tale, Language rode that fiber bloom when the species set sail. [Chorus] Arcuate arcs from the mouth to the ear, Geschwind's junction is the layover here, MdLF runs the middle highway through, Temporal pole to a parietal view, VOF stands vertical, occipital spine, Ventral meets dorsal on a north-south line, Three tracts weaving through the parietal crew, Sing the wiring and the meaning comes through. [Verse 3] Nineteen eighty-four, Seltzer and Pandya found A middle longitudinal thread in the monkey's mound, Twenty-oh-nine Makris brought it to the human skull, Superior temporal gyrus, temporal pole, Stretching to the IPL, the SPL beside, Parieto-occipital, a lateral ride, Language or attention, the debate's still raw, Audiovisual binding, nobody's found the law. [Verse 4] Eighteen eighty-one, Wernicke sketched a vertical thread, Buried in the archives for a century, left for dead, Yeatman woke it up in twenty-fourteen, PNAS in hand, Linking word-form cortex to the dorsal band, Takemura traced it to the V3A, V3B site, Intraparietal sulcus catching ventral light, Reading needs the handshake, dorsal meets the shape, VOF's the cable where the two streams drape. [Bridge] Three fascicles, three different jobs, Direct and indirect, the long way it lobs, Expansion, rediscovery, a timeline of names, Catani, Rilling, Yeatman - count the claims, The parietal lobe isn't some lonely little isle, It's a switching station, routed mile after mile. [Chorus] Arcuate arcs from the mouth to the ear, Geschwind's junction is the layover here, MdLF runs the middle highway through, Temporal pole to a parietal view, VOF stands vertical, occipital spine, Ventral meets dorsal on a north-south line, Three tracts weaving through the parietal crew, Sing the wiring and the meaning comes through. [Outro] Arcuate, MdLF, VOF - say it slow, Geschwind's territory - now you know, Dorsal, ventral, hand in hand, The parietal lobe commands the strand.
