In addition, absolute mid
beta waves increased in the same regions (left frontal and right parietal) and these changes might be enhancing the alertness state.
Stroop
Beta Waves: Initial
beta waves recorded during Stroop testing ranged from 11.
Persons who abuse alcohol chronically have been found to have lower levels of alpha and theta waves and an excess of
beta waves, perhaps contributing to use of alcohol to raise levels of those brain waves to a more pleasant state of relaxation (Peniston & Kulkowsky, 1989).
Beta waves (13-18 Hz) are needed to solve a problem or complete a task.
The current increased the activity of normal
beta waves -- a kind of brain wave that is usually active during sustained muscle activities, such as holding a book.
The EEG studies showed an increase in
beta waves and a decrease in spike wave discharges.
Gamma waves are present during sound sleep; theta waves indicate dozing or sleeping;
beta waves are present during an awake, excited state and alpha waves signify an awake, relaxed state.
