The Rhythms of the Brain Shape Our Perceptions

Focusing on what's important - this is one of the main tasks of our brain. After all, countless amounts of information are constantly flooding our senses. But how do we manage to separate the important from the unimportant? It has long been known that oscillatory neural activity is a key factor for this attentional selection in the mammalian brain. Scientists from the German Primate Center in Göttingen and the University of Melbourne 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.
