[Verse 1] Past the cell body, branches unfurl, reaching like fingers catching news from the world, no trunk toward heaven, no leaf, no bark, just a hungry little forest growing in the dark. This is the dendrite, the listening end, a thousand tiny doorways where the signals bend, together they're called the dendritic tree, architecture of attention, built for you and me. [Chorus] Dendrites, dendrites, gathering the spark, branching like a thicket blooming in the dark, spines like tiny mushrooms, sprouting what you learn, ten thousand whispers pooling till the message starts to turn. Catch it, weigh it, pass it on, the shape of every branch decides which thought gets drawn. [Verse 2] Zoom in closer, past the naked eye, tiny mushroom studs are standing by, one micron tall, they're small but they're alive, this is where excitement lands and synapses thrive. Practice your scales, a spine will swell and stay, skip the lesson weeks, it shrinks and fades away, they're not fixed forever, they're not set in stone, spines are sculpted daily by the thoughts you've grown. [Verse 3] A pyramidal neuron, cortex's quiet sage, holds ten thousand inputs like letters on a page, but the Purkinje cell, in cerebellum's hall, answers two hundred thousand, the champion of them all. Its arbor spreads out flat, a fan someone unrolled, catching parallel fibers like a net woven gold, more branches, more listening, more voices in the choir, each dendritic tree built to its own desire. [Chorus] Dendrites, dendrites, gathering the spark, branching like a thicket blooming in the dark, spines like tiny mushrooms, sprouting what you learn, ten thousand whispers pooling till the message starts to turn. Catch it, weigh it, pass it on, the shape of every branch decides which thought gets drawn. [Verse 4] These signals aren't all-or-nothing, no dart shot clean and fast, they're graded, shifting, fading as the distance they have passed, they attenuate — that means they're weakening with space — unless the dendrite fires its own small spike to keep its pace. A local surge can rescue what was turning faint and pale, so even far-off knocking still delivers its own tale, and the shape of every branch point, every fork along the way, decides if whispers gather or if they cancel and decay. [Bridge] Neurons arborize — that's branching out to greet every passing signal that the dendrite's built to meet. Geometry's the logic, before a thought is born, the tree decides the meaning long before it's ever sworn. Not just wires waiting, not just cable, not just thread — the branching is the thinking, the math is in the spread. [Chorus] Dendrites, dendrites, gathering the spark, branching like a thicket blooming in the dark, spines like tiny mushrooms, sprouting what you learn, ten thousand whispers pooling till the message starts to turn. Catch it, weigh it, pass it on, the shape of every branch decides which thought gets drawn.
