Universal theory of brain waves From linear loops to nonlinear synchronized spiking and collective brain rhythms

Although very complex (with extensive mathematics) this paper comes with some clues of how brain waves can propagate and generate different frequency synchronism, that as they explain are not directly related to physical tracks but is a electrostatic field derived phenomena.

" In conclusion, in this paper we have presented an inhomogeneous anisotropic physical model of wave propagation in the brain cortex. The model predicts that in addition to the well-known damped oscillator-like wave activity in brain fibers,there is another class of brainwaves that are not directly related to major fibers, but instead propagate perpendicular to the fibers along the highly folded cortical regions in a weakly evanescent manner that results in their persistence on timescales long compared to waves along brain fibers." {Credits 1}

" The unusual dispersion properties of those waves provide a universal physical mechanism for emergence of low frequencies from high-frequency oscillations." {Credits 1}

" The ranges of parameters for the waves produced by our model are in agreement with those presented by several studies [7] that show evidence that electrostatic field activity in several areas of animal and human brains are traveling waves that can affect neuronal activity by modulating the firing rates [7] and may possibly play an important functional role in diverse brain structures [8]. The natural self-organization of these traveling waves into looplike structures that our model produces agrees well with recently detected [6] cortical wave activity spatiotemporally organized into circular wavelike patterns on the cortical surface. Self-propagation of endogenous electric fields through a physical cut in vitro when all mechanisms of neuron-to-neuron communication have been destroyed [9] can potentially be attributed to these waves as well." {Credits 1}
