- Alpha and gamma coherence trended upward
- Before-and-after design; no control group
Corporate executives attending a five-day yoga-based stress-management program (Self Management of Excessive Tension) had their EEG recorded on the first and last days. Coherence rose in the delta band and trended upward in alpha and gamma, which the authors link to emotional stability, while noting that a before-and-after design needs a randomized follow-up.
