Abstract :
It is known that the biological activity of the brain involves radiation of electric waves. These waves result from ionic currents and charges traveling among the brain s neurons. However, it is obvious that these ions and charges are carried by their relevant masses that should give rise, according to the gravitational theory, to extremely weak gravitational waves. We use in Part I of this work the stochastic quantization (SQ) theory to calculate the probability to find a large ensemble of brains radiating similar gravitational waves. We also use this SQ theory in Part II of this work to derive the equilibrium state of the quantum fluctuations related to the known Lamb shift.
