The further deductions from this model were surprizing: electromagnetic nature of life and consciousness, electrostasis, bioplasma, and laser effects in biosystems. In 1984, the present author suggested a model that was enhanced with quantum interdependencies. It has been called "the quantum seam of life" /Fig. 2/.
