Alpha Waves screw up Visual Processing

In the article "Controlling brain waves to stay visually aware"

"researchers at Beckman Institute have used a novel technique to determine how the brain processes external stimuli that reach (or don’t reach) our awareness."

We found that the same brain regions known to control our attention are involved in suppressing the alpha waves and improving our ability to detect hard-to-see targets,” said Diane Beck, a member of the Beckman’s Cognitive Neuroscience Group, and one of the study’s authors.
