Mikäli tuon oikein ymmärsin, kaikissa muissa allamainituissa meditaatiotekniikoissa
paitsi TM:ssä (transsendenttisessa meditaatiossa) aivoaaltojen
koherenssi oli *vähäisempää* meditaation aikana kuin levon aikana!
http://www.sciencedirect.com/science/article/pii/S1053811912000596ll significant differences (corrected for multiple testing) between meditation
compared to no-task rest before and after meditation showed lower coherence
during meditation, in all five traditions and eight (inhibitory as well as
excitatory) frequency bands.
"all five traditions" = experienced meditators (13 Tibetan Buddhists, 15 QiGong,
14 Sahaja Yoga, 14 Ananda Marga Yoga, 15 Zen)
"Note that all significant cases had lower coherence during meditation than
rest,"
as opposed to:

"Compared to rest periods the practice of TM produced an increase in alpha phase
synchrony primarily between anterior and posterior regions."
"he dominant pattern in some long-term TM practitioners was a zero-lag condition
over the whole cortex without a nodal line of phase reversal in the middle. This
means that ô°‚ every 50 ms the whole cortex reverses polarity (Fig. 4).
These global zero-lag events accounted for the results of the study that showed
an increase Aâ€"P phase synchrony (a decrease in phase time lag) during TM.
A
condition of zero-lag over the whole cortex suggests an open-end standing wave
that results from two perfectly timed waves of the same frequency traveling in
opposite directions. This kind of wave is not structured through reverberation."
