Abstract:
Global-electrocortical activity is being modeled as a system of driven harmonic oscillators, considering telencephalonic structures as masses of linked oscillators generating activity at a number of resonant modes. This paper proposes the covariant-enhanced-coupling model of global-electrocortical activity of the human brain, which is a generalization of the covariant-generalized-coupling model. Enhanced coupling is dependent, not only, on the electrical potentials, but also, on their first and the second time derivatives. The signal equations, which were, originally, set up in the comoving frame, are transformed into the laboratory frame, expressed in the covariant notation using tensorial representation. This brings in the magnetic field in addition to the electric field.
