This is achieved by increasing sensory motor rhythm (SMR or low beta waves) and lowering theta waves (Wilson, Thompson, Thompson, & Peper, 2011).
Referring to Theta / Betha training, a positive impact can be observed, so through this the Theta / Beta tax was reduced (Bakhshayesh et al., 2011) or the presence of theta waves are decreased and Betha waves are increased (Gevensleben, Holl, Albrecht, Vogel, et al, 2009; Gevensleben, Holl, Albrecht, Schlamp, et al, 2009,..
Palmer' noted a prevalence of theta waves in volunteers who he had taught to have OBEs at will through the use of relaxation and suggestion.
For all the phases of [f.sub.1], [f.sub.2], and [f.sub.3], Alpha waves ([B.sub.1]) are decreased significantly and transferred into Theta wave ([B.sub.3]) and Delta wave ([B.sub.4]) standing for the slights sleeping status.
High theta waves immediately before being prompted to remember an item were associated with better performance.
The researchers found that compared with the resting state, meditation involved more abundant theta waves (associated with relaxed attention and alertness) across all brain regions, and especially in the frontal and temporal-central areas of the brain.
* Theta: Theta waves are faster than delta waves, but still slow and typically are correlated with light sleep, daydreaming, inattention, creativity, and self-hypnosis.
Instead, he found changes in the theta waves, which record the activity of the parietal regions.
