Q1: Which 90-minute video is the closest to meditation where the Left and Right brain hemispheres communicate best? Q2: Am I correct in assuming that for concentration with work, I would use the Video for study? Thank you
Any binaural beat is going to give you the same amount of left-right communication. I don't have any 90-minute meditation tracks yet. Correct, "focused studying" is good for any kind of work!
