General Theory of Coherent Excitations on Biological Systems

  • H. Fröhlich


Coherent excitations, as first proposed in 1968, can arise in the presence of nonlinear interactions if metabolic energy is supplied at a rate s above a critical so. Three types of excitations will be shown to exist: A excitation of a single mode; B excitation of a metastable highly polar state; C excitation of limit cycles or Lotka-Volterra oscillations in complex systems. They may have far reaching consequences on the dynamics of biological systems.

Externally applied radiation may, at certain frequencies and at certain stages of development, act as trigger to biological events. In this case a steplike dependence on the intensity is to be expected.

Relevant experimental evidence will be indicated.
