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).
(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.
