EEG (electroencephalography) technology is used to measure brain's electrical vibrations from the surface of the scalp. The resulting EEG pattern will contain frequency elements mainly below 30Hz. The frequencies are categorized into four states as follows.

The dominant frequency in the brain's EEG pattern determines what shall be called the current state of the brain. If the amplitude of the alpha range frequencies is highest, then the brain is said to be in the alpha state. The purpose of Brainwave Podcast is to affect the brain's state to achieve different results.

Brain's EEG pattern always consists of a wide range of different frequencies. The most dominant of them determines the current state of mind, but note that this is not any "exact frequency the brain is operating on". There are always also other frequency components present.
