Scientists discover ancient brain cells that help block distractions

Researchers have identified a small cluster of neurons in an ancient region of the brain that acts as a natural focus filter, helping you concentrate by screening out distractions.

As soon as the neurons were reactivated, normal focus returned. The discovery could inform new approaches to understanding and treating attention disorders.
