[Verse 1] Nine modules dancing in the cortical maze Pyramidal neurons fire in intricate ways Basal dendrites catch the signals from below Apical branches reaching high where feedback flows Layer five cells with their crowns up in layer one Waiting for the top-down whispers to begun The dance of expectation meets reality's call BAC firing bridges the gap between them all [Chorus] BAC firing, BAC firing, when the branches align What is here meets what's expected in the neural design Apical dreams and basal facts collide Credit assignment flowing through the dendritic tide BAC firing, BAC firing, coincidence supreme Biology's teacher linking real to dream [Verse 2] Module one through nine assembled like a chain Each computation adding to the cortical brain Feedforward streams carry the current sensation While feedback loops bring anticipation The soma waits between these two domains Calcium spikes when both pathways maintain Their synchronized dance of prediction and proof The cortex computing under one neural roof [Chorus] BAC firing, BAC firing, when the branches align What is here meets what's expected in the neural design Apical dreams and basal facts collide Credit assignment flowing through the dendritic tide BAC firing, BAC firing, coincidence supreme Biology's teacher linking real to dream [Bridge] When apical tingles with the contextual glow And basal dendrites catch the data flow The magic happens in the soma's core Backpropagating action potentials explore Teaching every synapse what went right or wrong Canonical circuits singing nature's song [Verse 3] From thalamus rising to cortical peaks The architecture speaks what biology seeks Not just passive wires but active trees Computing probabilities in the neural breeze Each branch a question, each spike an answer The cortical ballet, a dendritic dancer Learning through coincidence, teaching through time The brain's credit system, sublime by design [Verse 4] Millisecond windows where timing is king Calcium channels open up and sing NMDA receptors guard the plastic gate Only when coincidence seals learning's fate The plateau potentials spreading through the tree Nonlinear magic setting synapses free Hebbian whispers in the dendritic crown Building the models that won't let us down [Chorus] BAC firing, BAC firing, when the branches align What is here meets what's expected in the neural design Apical dreams and basal facts collide Credit assignment flowing through the dendritic tide BAC firing, BAC firing, coincidence supreme Biology's teacher linking real to dream [Outro] Nine modules unified, the circuit complete Where dendrites and soma and axon all meet The canonical answer to learning's demand BAC firing rhythms across the brain's land
