Biocybernaut has Twenty Four Levels of Alpha Trainings. Alpha Trainings build on each previous training bringing you into richer and richer experiences and allowing your brain waves to organize and grow and synchronize more broadly across your head. Each successive training allows you to further advance in your Mind Mastery through increasing self-mastery of your own brain waves.
Alpha Two gives you feedback on all 8 channels, which are the left and right Frontals, as well as the left and right Temporals (in addition to the Alpha One feedback channels) . The feedback also includes hemi-coherence on four Left Brain:Right Brain channel pairs.
