As activity levels at resting conditions are low, greater increases in delta and theta wave
activity can be achieved during mental work, corresponding to better performance.
At this age, we see the theta waves
of second-line consciousness replaced by faster alpha waves.
The results showed that within 30 minutes of consumption of Suntheanine, there was significant generation of alpha waves in the occipital and parietal regions of the brain but no observable increase in theta waves
Using the latest scientific technology from Australia, a person can be linked up to a set of wires which record alpha, beta, and theta waves
in the brain.
In contrast, theta waves
are associated with enhanced creativity, sensory integration, and altered states of consciousness.
Wallace et al has reported an increase in the intensity of alpha waves and occasional appearance of theta waves
for transcendental meditation (TM).
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.
Those who woke during REM sleep and successfully recalled their dreams were more likely to demonstrate a pattern of EEG oscillations called theta waves
in frontal and prefrontal cortex areas - the parts of the brain where our most advanced thinking occurs.
