Brainwave Generator

Moderately hack your brain by modifying your brain state.

Theory Behind BrainWave Generator

EEG and the brain's state 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:

State	Frequency range	State of mind
Delta	0.5Hz - 4Hz	Deep sleep
Theta	4Hz - 8Hz	Drowsiness (also first stage of sleep)
Alpha	8Hz - 14Hz	Relaxed but alert
Beta	14Hz - 30Hz	Highly alert and focused

The dominant frequency in the 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 stage. Note, that other frequencies still exist and it is impossible to give any "exact frequency your brain is operating on". However, later references to the brain states use the simplification of assuming that such a single frequency exists.
