[Verse 1]
Layer two stellate cells, packed tight in a diamond mesh,
Couey twenty-thirteen cracked the code beneath the flesh —
they don't shake hands direct, no excitatory wire,
they speak through parvalbumin, basket cells strike the fire.
PV interneurons wrap around like chandelier vines,
fast-spiking, tight axon, clamping down the firing lines.
Stellate fires, basket fires back, shuts the neighbor down,
lateral inhibition wearing a fast-spike crown —
the network runs on brakes, not engines side to side,
mutual silence sculpts the grid cell's traveling stride.
[Chorus]
Гальмування — це наш зв'язок, тормоз, не рука в руке,
Basket cell, PV cell, keep the module on the leash,
Стелейт до стелейт тільки через inhibition road,
Ритм у мозку — silence sculpts the grid cell's code.
[Verse 2]
Zoom past PV, other classes step onto the stage —
Somatostatin interneurons, slower on the page,
they hit the dendrite, not the soma, shape a different tone,
filter the input long before the signal's grown.
Every class got a rulebook, a target, a domain,
diversity of brakes is how you tune the terrain.
[Chorus]
Гальмування — це наш зв'язок, тормоз, не рука в руке,
Basket cell, PV cell, keep the module on the leash,
Стелейт до стелейт тільки через inhibition road,
Ритм у мозку — silence sculpts the grid cell's code.
[Verse 3]
Sürmeli twenty-fifteen mapped a hidden staircase run,
deep layers climbing back to layer two and layer one,
recurrent loop from five and six threading through the well,
feeding superficial stellates, closing up the shell —
not just a bottom-up highway, hippocampus writing back,
deep entorhinal circuits complete the feedback track.
[Bridge]
Silence the PV cells, watch the domino fall —
lose the mutual inhibition, lose the timing wall,
stellates fire together, lattice loses its shape,
hexagons blur to blobs, the grid begins to gape.
Тормоз пропав — і сітка розвалилась,
without the brake the beautiful pattern spoiled.
[Verse 4]
Giocomo oh-seven traced a gradient down the spine,
dorsal to ventral, grid scale stretching, growing wide,
HCN channels dense up top, sparse down below,
h-current shrinks the time constant, membrane starts to slow,
ventral cells relax longer, dorsal snaps back quick —
that time constant gradient makes the spacing click.
[Chorus]
Гальмування — це наш зв'язок, тормоз, не рука в руке,
Basket cell, PV cell, keep the module on the leash,
Стелейт до стелейт тільки через inhibition road,
Ритм у мозку — silence sculpts the grid cell's code.
[Outro]
Сітка тримається тормозом, mesh held by the brake,
deep talks to shallow, gradient shapes the scale —
sketch it in layer two, ask what silence would erase:
kill the basket, watch the hexagon disengage.
