[Verse 1] Stellate cells stacked in Layer Two, tight neighbors, never touching skin, No direct excitation whispered, no synapse slipped within, They don't hand the current forward, they route it through a middleman, A basket cell wearing parvalbumin badge, fast-spiking, hear the plan. Every stellate's a soloist, muted unless she's called, The basket cell's the conductor, and silence is installed. [Chorus] No stellate talks to stellate, gotta knock on the basket door, Parvalbumin gatekeeper, lean and fast, keeping score, Lateral inhibition, that's the rhythm, that's the code, Hush your neighbor, shape the bump — that's how the grid is sowed. [Verse 2] Couey twenty-thirteen, Pastoll the same year, hand in hand, Patch-clamp probing showed the wiring, proved the hidden plan, Stellate to stellate — nearly silent, a rumor left unheard, But stellate through basket back to stellate — now the current's stirred. Call it internecine current, cells locked in a hushing war, Each one dims the one beside it, yet a shape emerges from the score. [Verse 3] Picture a ring of excitatory cells arranged around a clock, Each one feeding one shared pool of inhibition, tick and tock, Run the simulation, watch the noise collapse to a single patch — That's your bump of persistent firing, nothing else to match. Nudge the input, watch it glide, smooth around the track, Proof that inhibition by itself can hold a place, then hold it back. Continuous attractor, running purely on restraint, No excitatory glue required, no extra paint — Just cells that quiet rivals till one glowing patch remains. [Verse 4] Out in the entorhinal cortex, grid cells chart the way you roam, Layer Two's the engine room, turning every footstep into home, Hexagons bloom from local hush, not some distant, wired call, One basket cell can rule a patch, keep order over all, Scale by scale, module by module, the lattice learns to sprawl, A whisper network built on silence, standing strong through it all. [Bridge] But not every cell drinks from that well, Calbindin-positive pyramidal cells ring their own bell, A separate excitatory network, running on its own design, Cholinergic modulation turns the dial, tone by tone, line by line, Different tribe, different wiring, sharing the same floor, Two circuits in one layer, each behind its own door. [Chorus] No stellate talks to stellate, gotta knock on the basket door, Parvalbumin gatekeeper, lean and fast, keeping score, Lateral inhibition, that's the rhythm, that's the code, Hush your neighbor, shape the bump — that's how the grid is sowed. [Outro] Silence is the sculptor, inhibition draws the map, Basket cells the chisel, stellate cells the clay you tap, Remember the mnemonic: no excitatory kiss direct, Only through the parvalbumin gate does the grid pattern connect.
