are strong when the brain's visual cortex is resting.
We observed left hemisphere dominant asymmetry in the presence of peppermint odor, alpha waves
with difference in amplitude of 100 [micro]v.
activity is related to cognitive activities of the brain [22, 33] and also there is a relation between better cognitive activity and higher alpha power during resting condition and the lower alpha power during cognitive tasks .
The Alpha-Stim, which is the size of a mobile phone, sends micro-currents of electricity to increase a patient's naturally occurring "alpha waves
" that are said to create a more relaxed state of mind.
(frequency range 8-12 Hz) are connected to "alertness and peacefulness, readiness, [and] meditation" (Demos, 2005, p.
The 5-Hour Energy[R] group rated alertness higher than other caffeine treatments, and was the only group to demonstrate decreases in alpha waves
, memory improvements, and impaired glucose homeostasis.
Experts say colouring-in is proven to be good for the brain, moving it into a chilled-out 'alpha waves
At a certain tempo alpha waves
are generated, which have been associated with a deep sense of concentration and focus."
state as my thoughts slowed, beta waves to alpha waves
, but I broke a
In Table 1, there are delta waves (frequency 0.5-4 Hz), theta waves (frequency 4-7 Hz), alpha waves
(frequency 8-13 Hz), beta waves (frequency 14-30 Hz), and gamma waves (frequency 30 Hz and over) .
showed that phase of modulation related to various delta subbands as very slow, slow, fast, narrow, cumulative slow 1, and cumulative slow 2 deltas with alpha waves
had different correlations with depth of anesthesia, and finally they implied that a fast delta subband was the best choice among various delta subbands to correlate with brain activities, and their phase difference changes with DOA .
The polysomnographic record showed bursts of REMS with alpha waves
characteristic of SP.
For all the phases of [f.sub.1], [f.sub.2], and [f.sub.3], Alpha waves
([B.sub.1]) are decreased significantly and transferred into Theta wave ([B.sub.3]) and Delta wave ([B.sub.4]) standing for the slights sleeping status.
with frequency between 8 and 13 Hz are associated with relaxation measured with EEG and directly stimulate the hypothalamus to produce endorphins among other functions.
Free time, unfocused thinking, access to alpha waves
helps the brain to be creative.
