[Verse 1]
Eighteen seventy-three, a silversmith of science
Golgi dips the tissue, paints it black with iron defiance
Only one in a hundred cells drinks up the stain
Lone black trees standing in a pale, unmarked terrain
Cajal leans in closer, candle burning low
Sketches every spine and branch the way the dark cells grow
Thousands of drawings, patient hand and eye
Where Golgi saw a forest, Cajal counted every spy
[Verse 2]
Golgi swears it's woven, one great tangled net
Reticular and seamless, every fiber interset
But Cajal says no — each cell stands on its own
A citizen, not fused flesh, a signal of its own
Dendrites drink the message in, the axon lets it go
One direction, never backward, that's the law we know
Nineteen-six, the Nobel stage, two rivals forced to share
Shaking hands in triumph while they're arguing right there
[Chorus]
Not one web — a billion threads unwoven
Dendrite in, axon out, that's the current flowing
Cell and cell, never touching, just a breath apart
Call it synapse, call it spark, this is where you start
Separate, connected, signal running one sure way
Cajal was right — the doctrine stands today
[Verse 3]
Sherrington coins a word in eighteen ninety-seven
Synapse — Greek for clasping, cells that touch like hands in heaven
Not merged but meeting, a junction, not a seam
Decades pass in argument, just theory, just a dream
Then the fifties bring the lens that finally could see
The interstice — that tiny gap, the space that sets cells free
Electron microscopes confirm what Cajal drew by hand
No fusion, only distance — now the whole world understands
[Chorus]
Not one web — a billion threads unwoven
Dendrite in, axon out, that's the current flowing
Cell and cell, never touching, just a breath apart
Call it synapse, call it spark, this is where you start
Separate, connected, signal running one sure way
Cajal was right — the doctrine stands today
[Verse 4]
Eighty-six billion neurons, Herculano-Houzel's tally
Packed inside your skull like stars inside a valley
A hundred trillion synapses, connections thick as frost
Lose the count, you'll never finish — that's the point, the cost
Every thought you're thinking, every word you say
Travels cell to cell to cell along the one-way way
[Bridge]
So remember: separate houses, never one continuous hall
Chemical and electric, whispers down the wall
This is just the doorway — circuits still to trace
Dendrite, soma, axon, gap — every neuron's place
Hold this doctrine steady, let the rest build from the ground
Billions of small voices make the one enormous sound
[Outro]
Not one web — a billion threads unwoven
Dendrite in, axon out, that's the current flowing
Separate, connected, signal running one sure way
Cajal was right — the doctrine stands today
Cell by cell, spark by spark, forever here to stay
