(1) 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]); that is, the biofeedback fabrics in conditions of 3 kinds of flashing frequencies for all samples are all effective in enhancing sleeping sense.
Level 1, meaning a predominance of alpha waves
, ranged from 0% (Session 12) to 12.7% (Session 11).
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.
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 .
