L'Étincelle
action potential — the all-or-nothing electrical spark that makes a thought exist
Lyrics
[Intro] Quiet now. Just the salt sea inside. A thin membrane, the only wall between what is and what could be. Negative seventy millivolts of peace. [Verse 1] Sodium waits outside the gate, a crowd pressing. Potassium is patient, inside. The pump works silently, a tireless bailer in a leaky boat, maintaining the difference. Just a whisper of stimulus. Not enough. Another. Closer now. The charge creeps up from the floor. [Chorus] But it is all or it is nothing. There is no *almost* a thought. No *maybe* a memory. You reach the threshold, or you stay in the quiet dark. L'Étincelle. The spark. The one, indivisible, irreversible… yes. [Verse 2] Luigi Galvani saw you in a dead thing. Late 1780s, a storm over Bologna. A frog's leg on an iron railing, touched by brass. It kicked. Not life, but the ghost of a message. He called it animal electricity. The spark in the meat. [Chorus] And it is all or it is nothing. There is no *almost* a kick. No *maybe* a twitch. You reach the threshold, or the leg lies still. L'Étincelle. The spark. The one, indivisible, irreversible… yes. [Bridge] Then Hodgkin and Huxley, in fifty-two. They took a giant axon from a squid, so big you could see it with your own eyes. They clamped its voltage, held it still. And watched you on a green screen, a wave of light. The sodium gate flying open. The rise. The fall. A beautiful, predictable storm. [Outro] And from that one wave, that single, perfect yes… a cascade down the line. The spark that becomes the word. The word that becomes the feeling. The all-or-nothing that becomes… …I remember. …I understand. …I do.
