[Verse 1] Three weeks in, the embryo's a flat little sheet Folds a groove down the back where the two edges meet That's the neural tube, born from skin called ectoderm A hollow pipe of promise, soft and still unfirm By week four it's sealed, a tunnel dark and small Every thought you'll ever have starts inside that wall [Chorus] Born and on the move, народжений в русі (born in motion) Climbing up the glia, рождённый для пути (born for the road) Inside layer first, then outward we arise Born and on the move — дивись, як місто будується (watch the city build itself) Cell by cell, a city rising to the skies [Verse 2] Radial glia stand like ladders by the ventricle's shore Dividing, dividing, they keep making more A quarter million neurons, every minute at the peak Factory of thought that never pauses, never takes a break Stem cells splitting fast beside the fluid-filled hall Building up the mind before you can recall [Chorus] Born and on the move, народжений в русі Climbing up the glia, рождённый для пути Inside layer first, then outward we arise Born and on the move — місто будується [Verse 3] Pasko Rakic watched them climb the fiber like a vine Each new neuron passes the ones born before in line Inside-out's the order — the deepest layers come first Later-born cells climb higher, racing past the first Six layers of cortex stacked from bottom to the rim Built along a radial glia's guiding limb [Verse 4] Cajal-Retzius cells drop a protein called Reelin down A stop sign in the traffic — "settle here, don't skip town" Without it, cortex folds collapse, the brain turns smooth and bare Lissencephaly's the word for a brain that lost its layered stair Smooth as a river stone, missing its folded crease Reelin keeps the architecture, Reelin keeps the peace [Bridge] Not every cell climbs straight — some wander sideways, free From the ganglionic eminence, a tangential odyssey Interneurons slide in sideways, hushing the circuit's shout Inhibition finds its home without a radial route Тангенціально, вбік вони йдуть (tangentially, sideways they go) Quietly weaving calm into the overgrown crowd [Verse 5] Synapses spark where axons meet, a million bridges wired Pruning trims the branches that the circuit never required Myelin wraps the pathways, speeding signals down the line A lifetime of refinement, sculpting thought by design The tower keeps on growing long after birth's first cry Born and on the move — we never stop, we only climb [Chorus] Born and on the move, народжений в русі Climbing up the glia, рождённый для пути Inside layer first, then outward we arise Born and on the move — місто будується [Outro] Born and on the move, рождён, чтобы идти (born just to go) From tube to tower, every neuron finds its sky Народжений в русі — the building never stops Born and on the move, until the circuit locks
