Abstract

Biomaterials are primarily insulators. For nearly a century, electromagnetic resonance and antenna–receiver properties have been measured and extensively theoretically modeled. The dielectric constituents of biomaterials—if arranged in distinct symmetries, then each vibrational symmetry—would lead to a distinct resonance frequency. While the literature is rich with data on the dielectric resonance of proteins, scale-free relationships of vibrational modes are scarce. Here, we report a self-similar triplet of triplet resonance frequency pattern for the four-4 nm-wide tubulin protein, for the 25-nm-wide microtubule nanowire and 1-μm-wide axon initial segment of a neuron. Thus, preserving the symmetry of vibrations was a fundamental integration feature of the three materials. There was no self-similarity in the physical appearance: the size varied by 106 orders, yet, when they vibrated, the ratios of the frequencies changed in such a way that each of the three resonance frequency bands held three more bands inside (triplet of triplet). This suggests that instead of symmetry, self-similarity lies in the principles of symmetry-breaking. This is why three elements, a protein, it’s complex and neuron resonated in 106 orders of different time domains, yet their vibrational frequencies grouped similarly. Our work supports already-existing hypotheses for the scale-free information integration in the brain from molecular scale to the cognition.

Highlights

  • A significant portion of our brain exhibits a scale-free dynamic in the electrical field potentials and in the magnetic resonance responses [1]

  • Temporal correlations of brain’s cognitive responses are widely studied [2], no reports exist for the scale-free temporal correlations connecting a single protein to a single neuron via intermediate structures

  • Establishing a connection is important since Ghosh et al [7] have shown using coaxial probe that far believed micro and neurofilaments are not silent inside the axon initial segment, AIS, they vibrate and exchange signal with various dendritic and axonal branches before the soma builds up the axon potential [7]

Summary

Introduction

A significant portion of our brain exhibits a scale-free dynamic in the electrical field potentials and in the magnetic resonance responses [1]. These studies started in the 1930s and finding the fractal feature in the resonance frequency spectra is an abundant tool, frequently used in wide ranges of research fields Be it a single tubulin protein, or a single microtubule or a neuron membrane, the dielectric resonance measurement is a routine task except that we use precise coaxial probe which because of its atomic sharp needle ensures that the precise contact is made with the material and environmental noise is drastically reduced. Two efforts were made: first, reducing the water layer so that only the surface ions flow between the electrodes, and second, using coaxial probe connected to a piezo motor enabling a controlled precise route to measure the ionic conduction of any biomaterial surface or inside Another unique advantage of this probe was that one could measure the dipolar oscillations at MHz or GHz using the inner Pt probe simultaneously, with the ionic signal using Au electrodes as shown earlier by Ghosh et al [7]. Once we are in the favorable wet domain, measurements of electromagnetic resonance are carried out
