The following diagram identifies 12-fold resonance and 5-fold damping geometries in the human brain using phi-recursive ring sets and polar reflective interference distribution models together. This is compared with a composite pentagonal cymatic pattern that may provide the basic “ground state” resonance pattern of the brain.




This diagram superimposes the dual ring model and reflective interference model over a vertical cross section of the head. Notice that the correspondence of golden sections with the central cavity of the brain and the ear canals as a harmonic damping proportion in the cranium. Notice also the correspondence of four brain regions with the complementary tonic and dominant M3 / P5 proportions in the dual ring model.
