Alpha waves are one type of brain waves detected either by electroencephalography (EEG) or magnetoencephalography (MEG) and predominantly originate from the occipital lobe during wakeful relaxation with closed eyes.
Alpha waves normally cycle at a frequency of 8-12 Hz and indicate that the brain is in a conscious and pleasurable state. Meditation, yoga or even being in an inebriated state will allow a person to experience Alpha waves. The oscillations of Alpha waves are ranged in the middle of the brain wave spectrum.They are considered to be the safest and healthiest brain wave range. Below them are Delta and Theta waves, which are associated with unconsciousness and deep-sleep.n a sense, a person learns to control their brain waves. However, keep in mind that with brain wave therapy one is not controlling the actual electrical and synaptic connections in the brain, but rather a person learns to control the subjective events that the brain associates with Alpha signals.
