[Verse 1] Load the macaque connectome data, CoCoMac in your hands Map each region as a vertex, every synapse where it stands Calculate the clustering coefficient, then the shortest path you trace Small-world networks have that special clustering plus short pathways through space Random graphs would scatter loosely, lattice grids would cluster tight But cortical columns dance between them, short connections burning bright [Chorus] Small-world clustering with pathways lean Communication through coherence, frequencies align and synchronize the scene VSA addressing plus thalamic routing clean Neuromodulator broadcast, distributed computational machine Graph theory meets the neural streams Building models of cortical dreams [Verse 2] Code two populations oscillating, gamma rhythms in the night Population A at forty hertz, population B at fifty bright When frequencies match precisely, information flows like gold But mismatched rhythms block the signal, selective transfer takes control Coherence gates the neural traffic, synchronized waves carry data Phase-locked loops enable binding, temporal codes in brain strata [Chorus] Small-world clustering with pathways lean Communication through coherence, frequencies align and synchronize the scene VSA addressing plus thalamic routing clean Neuromodulator broadcast, distributed computational machine Graph theory meets the neural streams Building models of cortical dreams [Bridge] Vector symbolic architecture handles content addressing schemes High-dimensional random vectors, binding memories in semantic dreams Thalamic nuclei route the signals, switching matrices of thought Neuromodulators flood the system, global state changes are bought Three mechanisms working together, each one serves a different role Hybrid models capture cortex, computational control [Verse 3] VSA gives you storage power, distributed patterns encode Clean up memories from corruption, associative recall mode Thalamic routing directs attention, spotlight searching through the maze Neuromodulator chemicals alter, motivation sets the blaze Dopamine shifts exploration, acetylcholine tunes the gain Serotonin shapes the learning, cortical columns break the chain [Chorus] Small-world clustering with pathways lean Communication through coherence, frequencies align and synchronize the scene VSA addressing plus thalamic routing clean Neuromodulator broadcast, distributed computational machine Graph theory meets the neural streams Building models of cortical dreams [Outro] Exercises map the neural cosmos, exercises build the code Three components working as one, down the computational road
