[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
