[Verse 1]
Four books deep in the medial wall, one map to rule the sprawl,
Book One's the spine, twenty-four modules standing tall,
Start at anatomy, brick by brick we build the frame,
Then cell types roll in, grid and border wear the name,
Functions next — the how, the why, the navigation trick,
Methods and clinical — patch clamp meets the sick,
Computational models close the loop, then synthesis ties the thread,
Twenty-four steps from cortex layer to a working head.
[Chorus]
One's the skeleton, Two's the zoom, Three's the engine, Four's the room,
Twenty-four, forty-one, then ten and ten again,
Anatomy to algorithm, running through my pen,
Stack the layers, name the parts, retention's how we win.
[Verse 2]
Book Two cracks it open, forty-one modules wide,
Every layer gets its verse, two through six, side by side,
Circuits mapped like subway lines, interneurons keep the beat,
Basket cells and chandelier firing incomplete,
Gradients stretch dorsal to ventral, scale on the climb,
Inputs coded — spike trains, tensors, formats every time,
And seven whole modules just for grid cells alone,
Hexagons in cortex, a lattice made of bone.
[Chorus]
One's the skeleton, Two's the zoom, Three's the engine, Four's the room,
Twenty-four, forty-one, then ten and ten again,
Anatomy to algorithm, running through my pen,
Stack the layers, name the parts, retention's how we win.
[Verse 3]
Book Three's the engine room, ten models, one per verse,
Continuous attractor nets keep the bump from getting worse,
Oscillatory interference, theta waves collide,
Residue codes count in primes, wrapping like a tide,
Vector navigation points you home without a map,
Kalman filters catch your drift, correcting every gap,
Successor representation predicts the road ahead,
Clone-structured graphs untangle context in your head,
Then TEM binds the structure to the sense you've fed,
Transformers weigh attention, vector-symbols spread instead.
[Bridge]
Ten readings, Coles-notes tight, Book Four's the crib sheet in the night,
O'Keefe's place cells, Moser's grid, Hafting's hex delight,
Fyhn and Fiete, Burak's math, Doeller's human sight —
Compress the paper, keep the punch, get the insight right.
[Verse 4]
So when the exam comes knocking, don't you fumble in the dark,
Book One's your frame, Book Two's your zoom, Book Three's the spark,
Book Four's your quick review before you walk the hall,
Twenty-four, forty-one, ten and ten — that's all.
[Chorus]
One's the skeleton, Two's the zoom, Three's the engine, Four's the room,
Twenty-four, forty-one, then ten and ten again,
Anatomy to algorithm, running through my pen,
Stack the layers, name the parts, retention's how we win.
[Outro]
Four books, one cortex, ninety-five modules strong,
Entorhinal architecture — now you know the song.
