Lyrics

[Verse 1]
Slide that microelectrode deep inside
Listen to the whispers neurons can't hide
Hubel and Wiesel with their steady hand
Built the foundation we still understand
V1 columns arranged in perfect rows
Simple cells fire when the line just flows
Complex cells dancing to orientation's call
Nobel prize waiting at the end of it all

[Chorus]
Record and correlate, that's how we see
What makes each neuron sing in harmony
From one electrode to a thousand strong
Population decoding proves the brain's song
But correlation ain't causation's twin
The bystander problem lurks within

[Verse 2]
Extended reaching to every domain
MT neurons love direction's refrain
V4 curved lines make the circuits glow
IT cortex where the objects show
Face patches mapping every subtle feature
Each electrode becomes our neural teacher
DiCarlo's decoding breaks the mystery wide
Information flows where behaviors reside

[Chorus]
Record and correlate, that's how we see
What makes each neuron sing in harmony
From one electrode to a thousand strong
Population decoding proves the brain's song
But correlation ain't causation's twin
The bystander problem lurks within

[Bridge]
Neuropixels dense arrays pierce the veil
Hundreds firing, telling neural tales
Linear readouts from the cortical stage
Unlocking secrets of the visual age
Single units whisper their tuning curves
Multi-unit chorus shows what each preserves
Fine grain analysis reveals the code
But causation needs another road

[Verse 3]
Ocular dominance carved in living stone
Simple complex cells each in their zone
Microelectrodes trace the visual stream
From retina's light to perception's dream
The method that built our field stands tall
Recording spikes that rise and fall
Correlation maps the neural terrain
But proving cause needs a different game

[Verse 4]
Spike trains dancing through the neural maze
Temporal patterns in millisecond phase
Rate codes whisper what the neurons know
While timing codes add to the show
Signal-to-noise ratios guide our way
Through cortical circuits night and day
Each action potential tells its tale
In the language where perceptions never fail

[Final Chorus]
Record and correlate, that's how we see
What makes each neuron sing in harmony
From one electrode to a thousand strong
Population decoding proves the brain's song
But correlation ain't causation's twin
The bystander waits to catch us in

[Outro]
Single units tell their faithful story
Multi-unit arrays reveal the glory
Fine grain recordings light the neural way
Building knowledge spike by spike each day
