This is achieved by increasing sensory motor rhythm (SMR or low beta waves) and lowering theta waves (Wilson, Thompson, Thompson, & Peper, 2011).

According to the frequency range, the EEG waves are categorized into five major EEG rhythms such as delta waves (0-4 Hz), theta waves (4-8 Hz), alpha waves (8-13 Hz), beta waves (13-30 Hz), and gamma waves (30-50 Hz).
However, the effect of caffeine on beta waves (13 to 30 Hz), which appear with mental focus, is less consistent.
The delta and beta waves were not altered by IR when compared with the control.
Considering variations, EBB was defined as low-amplitude bursts of rhythmic sharp beta waves of 20-30 Hz that were superimposed on low or moderate-amplitude delta waves of 1-4 Hz or theta waves of 4-7 Hz that could be rhythmic.

"There was a significant improvement in brain functioning for most participants, especially in the beta waves that are generally associated with anxiety,” says Ryan.
Using imaging and electrodes, researchers have discovered that, like biofeedback, meditation lets folks manipulate their brain's alpha and beta waves' rhythm, blocking out distractions or negative thoughts.
Indeed the results proved that gamma waves and beta waves as well over a broad range of frequencies carried AM patters that could be classified and categorized with odorants, but only if the subjects learned to respond to them as CSs through reinforcement training in classical or instrumental paradigms.
