In particular, the absolute beta waves such as low beta, mid beta, and high beta decreased mainly in the parietal regions during the inhalation through left nostril (Table 4).
Studies on beta waves are inconsistent, with some researchers reporting an increase in beta waves (Sigmon et al.
Most have increased slow wave (theta) activity in the frontal and central regions of the brain and reduced alpha or beta waves reflecting underarousal of the central nervous system (Leo & Barkley, 2005).
Often increasing low beta waves using a sensory motor-response protocol will help migraines and some seizure symptoms.
EEG studies: The electrical activity of the brain of the normal mock operated restrained rats was predominantly rapid with varying voltages (50-200 [micro]V) but no high voltage spike could be seen in these animals, either spontaneously or when provoked by flickering light and the frequency of alpha and beta waves were normal.
Beta waves are associated with increased concentration, alertness, and enhanced memory function.
In a 1996 study, co-workers given a 15-minute massage while sitting in a chair had lower levels of alpha and beta waves - indicating more mental alertness - than colleagues who simply sat quietly in their chairs and tried to relax.
