[Verse 1]
In Kandel's tome, the secrets hide
Cortical layers, six deep and wide
From molecular to polymorphic zones
Each circuit speaks in electric tones
Pyramidal cells reach up and down
While interneurons keep the sound
Of neural chatter well controlled
In columns structured, stories told
[Chorus]
Six layers stack like ancient towers
Circuits dance through cortical hours
From input streams to output fire
The canonical paths never tire
Columns process, networks compute
In Douglas-Martin's grand pursuit
[Verse 2]
Layer four receives the call
Thalamic whispers through it all
Then up to two and three it climbs
While five and six keep perfect time
The microcircuit's sacred dance
No movement left to random chance
Excitatory highways rise
While inhibition nullifies
[Chorus]
Six layers stack like ancient towers
Circuits dance through cortical hours
From input streams to output fire
The canonical paths never tire
Columns process, networks compute
In Douglas-Martin's grand pursuit
[Verse 3]
Now Hopfield builds his neural maze
Where memories persist for days
Attractor basins pull and hold
Each pattern like a story told
Energy landscapes guide the flow
To stable states that neurons know
When noise disrupts the perfect scene
The network finds what it has seen
[Bridge]
Synaptic weights like mountain slopes
Guide wandering signals toward their hopes
Each valley deep, a memory traced
No random walk, but mathematically placed
The cortex hums with Hopfield's dream
While Douglas shows the processing stream
[Verse 4]
From retina to visual cortex
These principles create complex
Representations rich and deep
In neural networks while we sleep
The same circuits that process sight
Also dream throughout the night
Consciousness emerges from
This orchestrated neural hum
[Verse 5]
Learning shapes the plastic brain
Through strengthening the synaptic chain
Hebbian rules govern the way
Connections grow from day to day
What fires together, wires as one
Until the neural web is spun
Into patterns we recognize
Behind our conscious mental eyes
[Chorus]
Six layers stack like ancient towers
Circuits dance through cortical hours
From input streams to output fire
The canonical paths never tire
Columns process, networks compute
In Douglas-Martin's grand pursuit
[Outro]
Three papers hold the master key
To cortical complexity
Kandel maps the territory vast
While circuits sing from first to last
