I recommend "brain hemisphere synchronization"

[Oskar]

I experience positive effects - at least temporally - when listening to music/sound that helps so called brain hemisphere synchronization and therefore recommend this to everybody else. Search “brain hemisphere synchronization” on YouTube for example and you will get some hits.

Please comment if you know a really good program one can buy that helps synchronization, thanks.
