How alpha waves affect cognition Alpha rhythms help filter irrelevant sensory inputs in the brain. Without proper filtering, the ability to carry out many basic cognitive operations can be crippled. Imagine the simple task of backing a car out of the driveway. In order to reach the street safely, you must hold your destination in mind while steering and ignoring distractions from every modality: news on the radio, children playing at the end of the block, an itch on your foot, the glare of the sun in your eyes. Most people filter out these distractions subconsciously — but should irrelevant stimuli distract you, backing out can become a difficult ordeal. This Brown University study is in line with other research on meditation, confirming previous findings that link enhanced attentional performance and fewer errors in tests of visual attention with meditation. While it’s still too early to declare meditation a cure-all for everything from attentional control to chronic pain, it’ll be fascinating to see what future research uncovers about this millennia-old tradition’s impact on the brain.
