[Verse 1] Basket cells wrap the soma like a wrestler's grip, Chandelier cells strike the axon, cut the signal at the hip, Parvalbumin, fast-spiking, no time to hesitate, Perisomatic snipers keeping stellate cells in place. Lateral inhibition, that's the whisper that they run, Every stellate cell competing till the strongest fires one, Gamma rhythm ticking, forty hertz on the clock, Septal GABA pulls the string, PV cells don't stop. [Chorus] PV punches perisomatic, fast and tight, the gamma bite, SOM slows the dendrite door, gatekeeping from the floor, VIP flips open locks, disinhibition rocks the box, Layer I lays a tonic blanket, calm the storm before we thank it. Basket, chandelier, dendrite, disinhibit — learn the four, Entorhinal circuitry, silence keeps the signal pure. [Verse 2] Somatostatin's slower, dendrite-targeting, no rush, Sits in layer one, controls the distal input's hush, Perforant path whispers reaching far along the tree, SOM decides which whisper turns into a memory. Modulating plasticity, deciding what can bend, Not the soma's bouncer — it's the sculptor at the end, While PV keeps the rhythm tight and locked in gamma time, SOM's the patient tailor stitching dendrites, line by line. [Verse 3] Then the VIP crew rolls in, 5-HT3aR tagged, Disinhibitory dominoes, they knock down what SOM had, Silence the silencer — that's the neuromodulator's trick, Acetylcholine calls, and the circuit breaks its stick. Layer one's neurogliaform, slow-release, no synapse tight, Volume transmission drifting like a fog through dendrite night, Tonic brake on distal branches, steady, never loud, Four cell types, one mission: keep the pyramidal crowd in line. [Verse 4] Buetfering found PV cells don't wear the hexagon crown, No grid pattern of their own, but space still shakes them down — Spatially modulated, tracking where you've been, Shaping stellate hexagons without wearing the skin. Miao ran the optogenetics, silenced PV, watched grids blur, Spacing warped, periodicity lost its architecture, Silence SOM instead — the theta coupling starts to sway, Speed signals stutter, gating slips, the pattern drifts away. Too much excitation and the network starts to spark, Inhibition's the seawall against that epileptic dark. [Chorus] PV punches perisomatic, fast and tight, the gamma bite, SOM slows the dendrite door, gatekeeping from the floor, VIP flips open locks, disinhibition rocks the box, Layer I lays a tonic blanket, calm the storm before we thank it. Basket, chandelier, dendrite, disinhibit — learn the four, Entorhinal circuitry, silence keeps the signal pure. [Bridge] Fast cells, slow cells, quiet cells combine, Every inhibitory thread pulls the grid cell's line, Ask yourself: silence PV, watch the hexagon crack, Silence SOM, the theta clock starts falling out of track.
