Scientists discover ancient brain cells that help block distractions

Scientists have discovered a tiny group of neurons in an ancient brain region that acts like a built-in focus filter, helping the brain ignore distractions and zero in on what matters most. When researchers temporarily switched off these neurons in mice, the animals became unusually distractible—similar to what is seen in ADHD—but regained normal focus as soon as the neurons were reactivated.
