Proc Natl Acad Sci U S A. 2026;123(15):e2515310123. doi:10.1073/pnas.2515310123 Lyrics:Verse 1In the quiet of a growing mind,A tiny cut decides the kind—Four letters slipped in, four left behind,And circuits learn their turn in time. Pre-ChorusA hidden switch beneath the seam,Turns ratios into lived-out dreams;Not how much, but how it’s split,Makes every signal choose its fit. ChorusFour letters, eight roads, one brain in bloom,Skips like lightning, lands like a tune;When the balance bends, the whole world shows—We are the splice, we are the glow. Verse 2One small enhancer, pulling it near,Keeps the stitch when the days are clear;Cut it out and the steps feel wrong,Learning stumbles where it belonged. BridgeThen activity hits—within an hour,The pattern flips, a sudden power;Too fixed, too full, no room to breathe,And distant memories start to leave. Final ChorusFour letters, eight roads, set by the code,A living map in a shifting load;Hold the middle, let it flow—We are the splice, we are the glow.
