Before revision:  Finally we apply our results to recent experimental observations that revealed the hitherto unknown periodic cytoskeleton structure of axons and measured the longitudinal fluctuations , and show how the comparison between our results and experiments limits possible local configurations and dynamics of the spectrin tetramers in the axonal cytoskeleton  .
After revision:  Finally we apply our results to recent experimental observations that revealed the hitherto unknown periodic cytoskeleton structure of axons and measured the longitudinal fluctuations , and show how the comparison between our results and experiments limits possible local configurations and dynamics of the spectrin tetramers in the axonal cytoskeleton and finally suggests simple but self-consistent dynamics of spectrins in which the spectrins in one spatial period of axons fluctuate in-sync .
