Just as a tuning fork has natural frequencies for sound,
the planet Earth has natural frequencies,
called Schumann resonances,
for electromagnetic radiation.

The Human Brain also has natural frequencies
for electromagnetic radiation.

It turns out that the Earth's Schumann resonances are
"in tune" with the Human Brains's Alpha States and Theta States.

"So long as the properties of Earth's electromagnetic
cavity remains about the same, these frequencies remain the same.

The solar sunspot cycle may change the frequencies,
because the Earth's ionosphere changes in response to
the 11-year cycle of solar activity."
