The ability to pay attention to relevant information while ignoring distractions is a core brain function. Without the ability to focus and filter out “noise,” we could not effectively interact with our environment.
But despite much study of attention in the brain, the cellular mechanisms responsible for the effects of attention have remained a mystery.
