[Verse 1] When neurons fire, what does summation mean? Without the timing, it's an empty scene Location matters - proximal or distal Makes the difference - crystal clear or mistal Dendrites branching like a cosmic tree Each input landing where it needs to be Temporal windows, spatial segregation Define the rules of neural integration [Chorus] Four knobs spinning in the dendritic maze Time and place and amplitude and phase Standard ANNs got just one to play Static weights in a frozen array Summation's vague until you specify When and where the signals multiply [Verse 2] ANN units stripped down to the bone One degenerate knob they call their own Number four - the weight that's trained and set But timing, location - those they forget Real dendrites dance with four dimensions Artificial ones lack comprehension Backprop dreams of gradient descent While biology's got different intent [Chorus] Four knobs spinning in the dendritic maze Time and place and amplitude and phase Standard ANNs got just one to play Static weights in a frozen array Summation's vague until you specify When and where the signals multiply [Bridge] Proximal synapses hit the soma hard Distal ones get filtered in the yard Coincidence detection needs precise timing NMDA gates with calcium climbing While your neural network weights stay static Real dendrites flow like mathematics [Verse 3] Checkpoints teach us what we're missing here Four dimensions make the picture clear ANNs collapse the temporal domain Spatial processing goes down the drain Only amplitude survives the translation Lost the rhythm, lost the computation Biology's orchestra plays four-part harmony Artificial minds hear monotony [Verse 4] Evolution crafted this design Four billion years of fine-tuning time Each synapse placed with surgical precision Every timing window, tough decision We build machines that barely scratch the surface Miss the depth of neural circus Four knobs turning, signals integrating While AI waits for us to catch up, waiting [Chorus] Four knobs spinning in the dendritic maze Time and place and amplitude and phase Standard ANNs got just one to play Static weights in a frozen array Summation's vague until you specify When and where the signals multiply [Outro] Next time someone says summation Ask them for specification Where and when and how much flow That's what dendrites really know [Final Chorus] Four knobs spinning in the dendritic maze Time and place and amplitude and phase Standard ANNs got just one to play Static weights in a frozen array Summation's vague until you specify When and where the signals multiply
