It has long been known that oscillatory neural activity is a key factor for attentional selection in the mammalian brain. Scientists have now investigated how this works. They found that coupling lower frequencies of oscillations with higher ones allows fine-tuning the brain and is thus the basis for higher cognitive functions, such as selective attention.
