[Verse 1] In the cortex where the pyramids grow tall Dendrites branching like a waterfall Segregated trees with separate roles Apical feedback, basal controls Guerguiev showed us what the circuits hide Two-compartment neurons, side by side Forward pass flows through the basal domain While error signals climb the apical chain [Chorus] Dendrites dancing, learning how to learn Segregated branches, watch the patterns turn Backprop approximation in biological design Burst-dependent plasticity, keeping neurons in line Cortical columns computing distributed dreams Nothing is quite the way it seems [Verse 2] Sacramento's microcircuits tell the tale How biology makes gradient descent prevail Interneurons whisper inhibitory codes While pyramidal cells carry the loads Top-down predictions meet bottom-up drive In dendritic compartments, algorithms come alive Local learning rules that mirror global schemes Cortical mathematics, more than what it seems [Chorus] Dendrites dancing, learning how to learn Segregated branches, watch the patterns turn Backprop approximation in biological design Burst-dependent plasticity, keeping neurons in line Cortical columns computing distributed dreams Nothing is quite the way it seems [Verse 3] Payeur revealed the burst that breaks the code Calcium spikes on the apical road Hierarchical circuits synchronized in time Synaptic plasticity, rhythm and rhyme When predictions fail, the bursts begin Teaching deeper layers from within Coordinated learning across the brain's expanse Every dendrite gets its chance to dance [Verse 4] Layer five neurons reach both high and low Connecting cortical hierarchies in one flow BAC firing patterns bridge the neural divide While dopamine signals amplify and guide Contextual gates and multiplicative gain Transform raw signals in the learning brain Each dendritic tree a computational node In biology's elegant neural code [Bridge] From soma to the farthest dendritic tip Information processing on a roundtrip Biological networks learning to adapt Closing the gap where theory and practice overlap [Chorus] Dendrites dancing, learning how to learn Segregated branches, watch the patterns turn Backprop approximation in biological design Burst-dependent plasticity, keeping neurons in line Cortical columns computing distributed dreams Nothing is quite the way it seems [Outro] In every cortical column's computational space Dendrites orchestrate learning's embrace
