These changes only happened during the breaks and were the only brain wave
patterns that correlated with performance.
The tests further revealed that the brain appears to be actively processing magnetic information and rejecting signals that are not "natural." For example, when the vertical component of the magnetic field pointed steadily upward during the experiments, there were no corresponding changes in brain waves
. Because the magnetic field normally points down in the Northern Hemisphere, it seems that the brain is ignoring signals that are obviously "wrong." This component of the study could be verified by replicating the experiment in the Southern Hemisphere, Kirschvink suggests, where the opposite pattern should hold.
Higher slow-frequency amplitude (7, 8, or 9 Hz) brain waves
(while an individual's eyes are closed) are associated with greater vividness and imagery skills than lower amplitude brain waves
(Wilson, Thompson, Thompson, Thompson et al., 2011).
The brain waves
transition to fast-frequency waves that are visually very similar to the brain waves
seen during wakefulness, suggesting the brain is basically awake.
However, EEG readings showed preserved amplitude but delayed latency in difference waves, suggesting no significant disruption of brain waves
through the N400.
As a controller, there are video games that are starting to emerge that use brain waves
instead of joysticks.

For example, Cameron Shields, 10, of Hagersville, who attended his local Brain Waves
program last summer, learned new ways to interact with his grandfather Bryan who was diagnosed with a form of dementia called Pick's disease.
A mobile app under development can filter phone calls and reroute them directly to voicemail by reading brain waves
, cutting the need for users to press buttons on the smartphone screen.The app, called Good Times, is the brainchild of Ruggero Scorcioni, CEO and founder of Brainyno, who presented the technology at the AT&T Innovation Showcase in New York, where some of the company's top research projects were highlighted.
In the study carried out by University of California, Berkeley, scientists found that slow brain waves
generated during deep restorative sleep, which one experiences in youth, play a crucial role in transporting memories form a region in brain called hippocampus, where memories are stored for short term, to a region where these are stored for long term called the prefrontal cortex.
During this period of time, the participants' visual system will be stimulated and their brain waves
was changed and then recorded at every 10-seconds interval.
The brain holds in mind what has just been seen by synchronizing brain waves
in a working memory circuit, an animal study supported by the National Institutes of Health suggests.
and Wisconsin University--uses a single electrode to measure electromagnetic brain waves
, or EEG.
The hope is that imagined words can be uncovered by "reading" the brain waves
She "had no interest in seeing a shrink," he said, but she agreed to neurotherapy, a treatment that helps people train their own brain waves
to work differently.
