Alpha Brain Waves

The Research:
Alpha brain wave activity is generally associated with relaxed wakefulness, and alpha states are commonly described as tranquil and pleasant- sometimes accompanied by a "floating" feeling. Alpha frequencies are also indicative of a creative state of mind where free association is prominent. Alpha waves appear immediately and spread throughout the cortex when you close your eyes, which is part of the relaxation process leading to sleep.

Another interesting source of insight into the significance of alpha brain waves comes from extensive research that has found alpha to be a dominant wave length in the EEG scans of those who are actively meditating, and experiencing calm yet lucid, and sometimes "blissful" mental states, with minimal interruptive mental activity.

All of the studies above (with the one exception of Aftanas and Golocheikine, 2001 - selected here for its EEG scans) met Dr. Tina Huang's standards for inclusion in her landmark 2008 article, "A Comprehensive Review of the Psychological Effects of Brainwave Entrainment."
