Like a melody that keeps playing in your head even after the music stops, researchers have shown that the beat goes on when it comes to the human visual system. Researchers used periodic visual stimuli and electroencephalogram recordings and found, one, that they could precisely time the brain's natural oscillations to future repetitions of the event, and, two, that the effect occurred even after the prompting stimuli was discontinued. These rhythmic oscillations lead to a heightened visual awareness of the next event, meaning controlling them could lead to better visual processing when it matters most, such as in environments like air traffic control towers.
